Note: Existing YEWFLO Style C vortex flowmeters may be upgraded to provide the features and benefits of the New microprocessor-based Style «E» YEWFLO.

1.2PRINCIPLE OF OPERATION

1.2.1 Vortex shedding

How many of you have seen a flag flapping in the breeze on a windy day? Everybody has. How many of you have noticed that the flag flaps faster as the wind blows faster? Few haven’t. When you see a flag flapping in the breeze, you are witnessing the same phenomenon that makes a vortex flowmeter work. The flapping frequency is proportional to the velocity of the wind, and it’s linear! The flapping is caused by a vortex alternately being created on either side of the flag, and moving downstream with the wind. The vortex is a swirl of low pressure, like a tornado, that pulls the flag in the direction of the vortex. The passing of alternating vortices down the length of the flag causes it to flap. The faster the wind blows, the faster these vortices are created, and the faster the flag flaps. Frequency is proportional to velocity .

INTRODUCTION

The flapping flag is a familiar example of vortex shedding that everyone should be comfortable with. Here’s how it’s used in a vortex flowmeter. A non-streamlined part (bluff body) is inserted in the flow stream, this obstruction in the pipe causes vortices to be alternately created (shed). We call this part the ‘shedder bar’. The shedder bar in a YEWFLO performs two functions, it creates the vortices, and with the addition of our piezoelectric crystals senses them too. The crystals generate an alternating voltage waveform whose frequency is proportional to fluid velocity. The rest of the magic is taken care of in the electronics.

Figure 1.2.1: Karman Vortices

1.2.2K-factor

The most important fact about vortex shedding is that once the physical geometry, (pipe I.D., shedder bar width, etc.), are fixed, the frequency vs. flowrate (K-factor (pulse/gallon)) is unaffected by changes in viscosity, density or pressure over the operating range of the specific application. To determine the operating range use the YEWFLO Sizing program. On the other hand, an orifice plate is directly affected by changes in any of these parameters. There is a very small temperature effect due to expansion or contraction of the shedder bar width, which is easily compensated. Therefore, the K- factor created in our flow stand (all YEWFLOs are wet flow calibrated) on water, is accurate for gas too! Not so with an orifice plate. The benefit here is simplified calculations, and fewer things that

can effect accuracy .

Figure 1.2.2: Relationship between K-factor and Reynolds Numbers

INTRODUCTION

1.2.3Qmin

Those of you who haven’t used many vortex flowmeters may be wondering, ‘Why do we need to know viscosity, density, pressure and temperature?’. While the K-factor is unaffected by changes in viscosity, density and pressure, the velocity at which vortices begin to be created and become stable enough to measure accurately will vary. We refer to this velocity as Qmin, stated in desired flow units GPM, SCFH, etc. Here’s an example to help you understand. Let’s go back to the flag example. We’ve all seen the flag flapping in the breeze; however, on some days we can feel the breeze blowing, but the flag isn’t flapping. Why not? For the flag to flap, there must be enough breeze blowing, or energy, to lift the flag and create fully developed vortices. This is the same thing that happens in the vortex flowmeter.

The higher the fluid viscosity, the higher the velocity (more energy) required to start vortex shedding. On the other hand, the higher the density, the lower the velocity needed to start vortex shedding. In gases, viscosity and density can vary with pressure and temperature. Sounds complicated, but compared to an orifice plate it’s quite simple. By using the YEWFLO sizing program, vortex meter selection is simple. Simply enter the process conditions, the program will prompt you for them, and presto, a performance table for all meter sizes is generated. This performance table will help you select the best YEWFLO for the application.

1.2.4Uniquely vortex

Vortex shedding flowmeters measure flow digitally. This means, amplitude of the vortex signal is unimportant. As long as the flow is above the Qmin threshold, only the presence or absence of a vortex is important. Just like digital electronics, as long as the voltage is above or below a threshold value, it is either on or off. Digital flow measurement means no zero drift or span shift . Orifice plate flowmeters, for example, cannot make this claim, even if they are using microprocessor-based digital D/P transmitters, they still measure the small amplitude of deflection caused by differential pressure, and changes in temperature or pressure can shift zero and span.

1.2.5Vortex frequency

The YEWFLO uses piezoelectric crystals embedded in the shedder bar . Note that they are 1) hermetically sealed , and 2) surrounded by a heavy wall thickness , to protect them from the environment and the process. The positioning of the crystals is important. Although one crystal primarily measures flow frequency, it unfortunately picks up some pipe vibration noise. The other crystal is positioned such that it picks up primarily the pipe vibration noise. By electronically subtracting these two signals, we are able to obtain a high signal to noise ratio for the flow signal . The new Style «E» body design also improves the signal to noise ratio, by stiffening the shedder bar mounting in the measurement plane, further isolating it from pipe vibration.

1.2.6Available outputs

After processing the digital vortex frequency as described above, what outputs can you get? You can select either 4-20 mA output or voltage pulse, digital output. Output is selected by setting jumpers on the amplifier board, and the setting the software for pulse or analog output. Analog output is twowire, and pulse output is a three-wire connection (for details see the wiring section). The pulse output can be scaled over a range of 0-6000 Hz, down or up to maximize pulse resolution. Scaling up the frequency output can be done to improve resolution. The pulse output is also capable of driving many electromechanical totalizers directly without additional power.

QUICK START USING THE BT100/200

II.QUICK START

BT100/BT200 HANDHELD TERMINAL

Note: If you specified the correct process conditions on your order, these parameters have been preset at the factory; therefore, there is no need to re-enter the data.

The Style E YEWFLO is a smart communicating device with microprocessor-based technology. When used with Yokogawa’s BT100 or BT200 handheld terminal (HHT), YEWFLO can be configured to meet specific application needs. In addition, the optional local indicator/totalizer (TBL option) allows setting of various parameters.

When in the analog output mode, the HHT may be connected at any point on the instrument’s 4-20 mA loop. This connection superimposes a digital signal on top of the instrument’s 4-20 mA signal making communications completely transparent to your process signal. On the other hand, since there are no 4-20 mA wires in the pulse mode, direct connection of the HHT to the HHT

PULSE and HHT COM test points on the amplifier is necessary. Once connected, flowrate and total can be read, tag numbers entered, meter size or any other parameter modified as required. Additionally, you may activate or deactivate many features of the YEWFLO as necessary to meet the requirements of your application.

The HHT will enable you to scroll through the program until you locate the parameter that you wish to change. For communication information, see “How to communicate with the YEWFLO remotely” in the maintenance section. Please refer to the appropriate HHT instruction manual for details on each HHT.

To change a parameter using the BT100, insert the removable key in the lock and turn it clockwise

an alphanumeric value in any parameter. If this occurs, insert the key in the lock, turn it clockwise to the ENABLE position then press either the INC, DEC or alphanumeric key as before.

2.1PARAMETER SETTING IN BRAIN™ COMMUNICATIONS

The Model YF100*E Vortex flowmeter incorporates BRAIN™ communication functions. These functions enable the Vortex converter to remotely carry out the following functions by communicating with the BRAIN™ Terminal (BT100 or BT200), µXL, or Centum-XL distributed control systems.

•Setting or changing parameters required for vortex meter operation such as tag number, flow span and process conditions for example.

•Monitoring flowrate, totalized flow and self-diagnostics.

•4-20 mA loop check (simulated output) and totalizer reset.

Note: When the pulse/analog jumpers are set for a pulse output, Remote BRAIN™ communication on the 4-20 mA wires is not available. Therefore parameters cannot be set or read remotely. For the BT100 to operate in the pulse output mode, the instrument must be connected to the test points labeled HHT Pulse and HHT Com. This allows access to all parameters.

Note: Only the position of the jumpers affects remote communication ability, the software setting of pulse or 4-20 mA has no effect.

2.2YEWFLO SETUP

Note: If you specified the correct process conditions on your order, these parameters have been preset at the factory; therefore, there is no need to re-enter the data.

The purpose of a Quick Start is to address only those parameters which must be set to establish the operation of a meter for this application. Follow the parameters listed below and enter the data for your particular application.

With the BT100 or BT200 properly connected to the Vortex meter begin communicating by pressing the power button. After the power up sequence is complete, go to “ Menu B: SET 1”. The operation of the BT100 and BT200 are slightly different. Please refer to the ‘Basic Handheld Terminal Operation’ if you are unfamiliar with how to move through the menus and parameters. The following flow chart identifies only the parameters to be set, you may have to skip several parameters or menus to get to the parameters shown below. Be sure to enter all values and selections shown below or they will not be saved. If you make a typing error, use the CLR key to clear and re-enter.

QUICK START USING THE BT100/200

2.3PARAMETER SETTING IN HART™ COMMUNICATIONS

When specified, the model YF100*E vortex flowmeter can be provided with HART™ communication functions. (To determine if this field communication protocol has been incorporated in your instrument, confirm the “HART” suffix is a part of the YEWFLO model code.) These functions enable the vortex converter to remotely carry out the following by communicating with the HART communicator:

·Setting or changing parameters required for vortex meter operation such as tag number, flow span and process conditions.

·Monitoring flowrate, totalized flow and self-diagnostics.

·4-20 mA loop check (simulated output) and totalizer rest

The HART communicator can interface with YEWFLO from the control room, via direct connection to the amplifier, or any other wiring termination point on the 4-20 mA loop. Polarity does not matter. There must be a minimum of 250 ohms between the connection and the power supply. Refer to Figure 1.3.2 on page 7 for power supply voltage requirements and load resistance.

Note1: The output jumpers on the amplifier must be set to the analog position to communicate. Only the position of the jumpers affects remote communication ability, the software setting of pulse or 4-20 mA has no effect.

Note2: When Yewflo is supplied with the HART option, the TBL digital display/local operator interface cannot be used for parameter setting and configuration. Only two parameters are supported by the TBL:

Parameter E01: Total reset Parameter E02: Display Select

The amplifier has been pre-configured at the factory, so no setup should be required prior to installation. If your process conditions have changed and reprogramming is required, the menu/ parameter configuration list for YEWFLO/HART can be found in Appendix B in the back of this manual. Refer to the instructions provided with your HART communicator or operation details. The QUICK START section of this manual will address only those parameters which must be set to establish the operation of the meter for a particular application. Appendix B will cross-reference the BRAIN parameters to the corresponding HART parameters.

2.3.1Communication Specifications

Method of communication: Frequency shift keying (FSK). Conforms with Bell 202 Modem standard with respect to baud rate and digital “1” and “0” frequencies.

QUICK START USING THE BT100/200

Use the following formula to determine cable length for a specific application:

L = 65 x 106 — (Cr + 10,000) (R x C) C

where:

L = length in feet or meters

R = resistance in ohms (current sense resistance plus barrier resistance) C = cable capacitance in pF/ft or pF/m

Cf = maximum shunt capacitance of field device in pF

INSTALLATION

III.INSTALLATION

Before installing your YEWFLO you will need to gather the following tools:

Wafer Style:

1.Gaskets — self-centering preferred. In no case should the I.D. of the gaskets be smaller than the I.D. of the meter.

2.Wrenches — Two of a size appropriate for the nuts supplied.

3.Screw driver — A small Phillips or flat blade type may be used to connect lead wires.

4.Sufficient wire to reach from the meter signal converter to the power source, receiving device. See the Wiring Section of this manual for wire recommendations.

5.Stud bolts, washers and nuts are supplied with the meter

Flanged Style:

1.Nuts, bolts and washers appropriate in type, size, material and quantity for the flange as specified by ANSI standards.

2.Gaskets — self-centering preferred. In no case should the I.D. of the gaskets be smaller than the I.D. of the meter.

3.Wrenches — Two of a size appropriate for the nuts supplied.

4.Screw driver — A small Phillips or flat blade type may be used to connect lead wires.

5.Sufficient wire to reach from the meter signal converter to the power source, receiving device. See the Wiring Section of this manual for wire recommendations.

3.1PIPING REQUIREMENTS

To obtain maximum performance, the vortex flowmeter should be installed in a pipe with a straight run the same size as the nominal size of the meter. On the upstream side, the straight run depends on what is in the pipe ahead of the meter. In most installations a maximum of 20 diameters will be sufficient. The pipe on the downstream side of the meter should always be at least 5 diameters. The combination of flowmeter with upstream and downstream pipe is referred to as the metering run. Refer to the following illustrations for the minimum straight pipe for your installation. Note that in all installations the mating pipe on either side of the vortex meter must match the meter size. In many applications proper sizing may recommend using one meter size smaller than the existing pipe. When this is the case, concentric reducers should not be directly attached to the flowmeter, but installed on either end of the metering run as shown. In any case, the guidelines for orifice plate installations as published by the ASME will be safe to follow.

IDEAL

INSTALLATION

ACCEPTABLE

Figure 3.1.2: Reducer, expander, elbow and valve

If the meter cannot be located in the piping where the minimum straight run requirements can be met, it may be possible to install flow conditioning equipment upstream of the vortex meter and reduce the upstream piping without significantly reducing the accuracy. Contact your local representative or Yokogawa Industrial Automation for recommendations regarding flow conditioners.

3.1.1Pipe schedule

We recommend pipe schedule 40 for ½» through 2″ meter sizes. For meters larger than 2″, use schedule 80 pipe or smaller. If pipe schedule other than above is used, please refer to Parameter D05 to correct errors due to mismatched pipe schedule.

3.1.2Flow direction and orientation

Before installing the vortex meter verify the arrow on the meter body is facing the same direction as the direction of the flow. The direction of flow can be determined by the arrow on the shedder bar or clamping plate. The meter may be installed with the converter located above, below or to the side of the piping, whatever suits the selected installation location best. Flow may be horizontal or vertical, as long as the pipe is completely full. For liquid applications vertical flow up is preferred, as this guarantees a full pipe at all times.

3.1.3Pressure and temperature taps

If you are metering a gas where pressure and temperature compensation is required, pressure and temperature taps must be located downstream of the vortex meter. See Figure 3.1.3.

Figure 3.1.3: Pressure and Temperature taps

INSTALLATION

3.1.4Flushing the pipe

On a new installation we recommend flushing the pipeline and removing any and all scales on the inside of the pipe before installing the vortex meter. The bypass piping should be installed around the vortex meter to facilitate pipe cleaning. When there is no bypass piping, the vortex meter should be temporarily removed and a spool piece installed in its place.

3.1.5Gaskets

The ID of the gaskets must be equal to or larger than the ID of the meter and mating pipe. The gaskets should be the self-centering type. It is important that the gaskets not protrude into the flow stream, otherwise accuracy will be adversely affected.

3.2INSTALLING THE VORTEX METER

Before installing the vortex meter, verify the arrow on the meter body is facing the same direction as the direction of the flow.

3.2.1Installing the wafer style vortex meter

When installing the wafer type vortex meter it is important to align the instrument bore with the inner diameter of the adjacent piping. For meters in sizes ½» through 3″, four alignment collars are supplied. These collars establish a predetermined spacing between the mounting bolts and the outside diameter of the vortex meter body. The bolts must be of the proper diameter to establish alignment. Carbon steel stud bolts and nuts are supplied as standard. Stainless steel (304) stud bolts and nuts are optional. Gaskets are supplied by the user. Check all mating flanges ensuring all weld slag is ground off and the inside surface is clean and smooth.

Table 3.2.1: Dimensions

Note: Only the above indicated meter sizes require collars

3.2.2Installing the wafer style vortex meter horizontally

1)Insert two collars (see dimensions table above) on each of the two lower bolts.

2)Place the vortex meter on the collars located on the lower two bolts making sure the arrow on the side of the meter body is facing in the same direction as the flow.

3)Insert the remaining bolts and tighten all bolts and nuts uniformly.

4)Check for leakage between the meter body and the flanges.

Figure 3.2.1: Wafer type — horizontal installation

3.2.3Installing the wafer style vortex meter vertically

1)Insert one collar (if required, see table 3.2.1) on each bolt, being certain that the collars are in contact with the outside diameter of the vortex meter body. Make sure the arrow on the side of the meter body is facing the same direction as the flow.

2)Tighten all bolts uniformly.

3)Check for leakage between the meter body and the flanges.

INSTALLATION

CAUTION:

When installing the vortex meter in a vertical pipe outdoors we recommend rotating the conduit connection to face downward reducing the chance of rain and condensate running down the conduit into the housing.

Fig 3.2.2: Wafer type — vertical installation

3.2.4Installing the flanged vortex meter

Use bolts, nuts and gaskets in accordance with ANSI B16.5 (user supplied). The ID of the gasket must be equal to or greater than the ID of the meter bore. Self-centering gaskets are highly recommended.

3.2.5Insulating vortex meters with integral converter

When installing a vortex meter with an integral converter in a pipe to measure high temperature fluids, do not insulate the converter housing or mounting bracket. If it is necessary to insulate the entire installation, use a remote mounted converter. Custom steam jackets are available if necessary, please contact your Yokogawa Industrial Automation Representative for more information.

INSTALLATION

3.2.6Rotating the meter housing

The terminal box or converter housing may be rotated in 90º increments with respect to the pipe for viewing or wiring convenience.

3.2.7Remote converter terminal box rotation

1)Turn the power off.

2)Remove the terminal box cover.

3)Disconnect the lead wires from the sensor, Red (A) and White (B).
