Introduction
Transmitter Overview
2 Transmitter Overview
2.1Measurement principle
The Rosemount™ 5408 and 5408:SIS are two-wire transmitters for continuous level measurements over a broad range of liquids, slurries, and solids. The measurement principle is fast-sweep Frequency Modulated Continuous Wave (FMCW).
The transmitter continuously emits signal sweeps with a constantly varying frequency towards the product surface. Since the transmitter continuously changes the frequency of the transmitted signal, there will be a difference in frequency between the transmitted and the reflected signals (see Figure 2-1).
The frequency of the reflected signal is subtracted from the frequency of the signal transmitted at that moment, resulting in a low frequency signal which is proportional to the distance to the product surface. This signal is further processed to obtain fast, reliable, and highly accurate level measurements. See Figure 2-2 for a schematic overview of the signal processing.

2.2Process characteristics
2.2.1Dielectric constant
A key parameter for measurement performance is reflectivity. A high dielectric constant of the media provides better reflection and enables a longer measuring range.
2.2.2Foam and turbulence
Foaming liquids or turbulence may cause weak and varying surface echo amplitudes. The effects of turbulence are usually minor, but in the most challenging conditions, the transmitter may be mounted in a still pipe. In addition, measurement performance can be optimized by configuring the appropriate process conditions settings, see
Process conditions.
Transmitter Overview
Measurement in foamy applications depends largely on the foam properties. When the foam is light and airy, the actual product level is measured. For heavy and dense foam, the transmitter may measure the level of the foam’s upper surface. The Double Surface Handling function allows the user to select if the foam layer or product surface should be used as output (see Double surface handling).
2.2.3Dust
Dust is often present in solids applications, and even if the non-contacting radar is not affected by the dust in the vapor space, dust can be sticky and create a layer on the antenna. If this layer becomes too thick, it may affect the measurement. This is best managed by using air purging.
2.2.4Solid surface
Solids have some common characteristics which may cause weak and varying surface reflections. The surface is rarely flat or horizontal, the angle of the sloping surface differs during filling and emptying, and the dielectric constant of many solids is fairly
low.Table 2-1 presents common characteristics of some solids applications.
The parabolic antenna is ideal for applications with weak surface reflections. A larger diameter concentrates the radar beam and ensures maximum antenna gain. The parabolic antenna comes with a swivel connection that adjusts for angled tank roofs.

Transmitter Overview
2.3Vessel characteristics
2.3.1In-tank obstructions
The transmitter should be mounted so that objects such as heating coils, ladders, and agitators are not in the radar signal path. These objects may cause false echoes resulting in reduced measurement performance. However, the transmitter has built-in functions designed to reduce the influence from disturbing objects where such objects cannot be totally avoided.
Vertical and inclined structures cause minimal effect since the radar signal is scattered rather than directed back to the antenna.
2.3.2Tank shape
The shape of the tank bottom affects the measurement signal when the product surface is close to the tank bottom. The transmitter has built-in functions which optimize measurement performance for various bottom shapes.
2.4Application examples
The Rosemount 5408 and 5408:SIS are ideal for level measurements over a broad range of liquid and solids applications. The transmitters are virtually unaffected by changing density, temperature, pressure, media dielectric, pH, and viscosity. Non-contacting radar level is ideal for harsh conditions such as corrosive and sticky media, or when internal tank obstructions are a limiting factor.
Storage and buffer tanks
The Rosemount 5408 provides accurate and reliable level measurement for both metallic or non-metallic vessels containing almost any liquid (e.g. oil, gas condensate, water, chemicals).
Reactors
The Rosemount 5408 is ideal for the most challenging applications, including reactors where there can be agitation, foaming, condensation as well as high temperatures and pressures.
Transmitter Overview
Blenders and mixers
The Rosemount 5408 can help you withstand the rigors of blenders and mixing tanks. Easy to install and commission, it is also unaffected by virtually any fluid property change.
Open atmospheric applications
The Rosemount 5408 measures reliably in open applications, from short range sumps or ponds to long range dams.
Still pipe and chamber installations
The Rosemount 5408 is an excellent choice for level measurement in tanks with still pipes. It may also be used in chambers, but guided wave radar is generally the best fit for these applications. See Section 3.3.8 for installation guidelines.

Transmitter Overview
Bulk solids
The Rosemount 5408 is the ideal solution for small to medium sized silos with rapid level changes. The narrow beam avoids internal obstructions while still keeping good level measurement.
Safety applications
The Rosemount 5408:SIS is the ideal choice for safety functions such as overfill prevention, level deviation monitoring or dry-run prevention.

Transmitter Overview
2.6System integration
The transmitter is loop-powered, and uses the same two wires for power supply and output signal. The output is a 4-20 mA analog signal superimposed with a digital HART signal. The transmitter can be configured for either HART Revision 6 (default) or 7 (option code HR7). The HART Revision can be switched in field.
By using the optional Rosemount 333 HART Tri-Loop™, the digital HART signal can be converted into three additional 4-20 mA analog signals. With the HART protocol, multidrop configuration is possible. In this case, communication is restricted to digital, since current is fixed to the 4 mA minimum value.
The transmitter can be combined with the Emerson™ Wireless 775 THUM™ Adapter to wirelessly communicate HART data with IEC 62591 (WirelessHART®) technology. In addition, the transmitter can be connected to a Rosemount 751 Field Signal Indicator, or it can be equipped with an LCD display.
The transmitter can easily be configured by using a PC with the Rosemount Radar Master Plus software (running in the Instrument Inspector™ Application), a Field Communicator, the AMS Device Manager, or any other Device Descriptor (DD) or Field Device Integration (FDI) compatible host system.
The Rosemount 5408 and 5408:SIS are compliant with NAMUR NE 107 Field Diagnostics for standardized device diagnostic information.

3.3Installation considerations
Before installing the transmitter, follow recommendations for mounting position, sufficient free space, nozzle requirements, etc.
3.3.1Mounting position
When finding an appropriate location on the tank for the transmitter, the conditions of the tank must be carefully considered.
Consider the following guidelines when mounting the transmitter:
•For optimal performance, the transmitter should be installed in locations with a clear and unobstructed view of the product surface.
•The transmitter should be mounted with as few internal structures as possible within the signal beam, see Section 3.3.6.
•Do not install the transmitter in the center of the tank.
•Do not mount close to or above the inlet stream.
•Multiple Rosemount 5408 and 5408:SIS Level Transmitters can be used in the same tank without interfering with each other.
Mechanical Installation

/
3.3.2Free space requirements
If the transmitter is mounted close to a wall or other tank obstructions such as heating coils and ladders, noise might appear in the measurement signal. Therefore the following minimum clearance, according to Table 3-1, must be maintained.
For easy access to the transmitter, mount it with sufficient service space (see Table 3-2).

3.3.3Antenna size
Choose as large antenna diameter as possible. A larger antenna diameter concentrates the radar beam and ensures maximum antenna gain. Increased antenna gain permits greater margin for weak surface echoes.
In addition, a larger antenna diameter results in a smaller beam angle and thereby, less interference from any internal structures in the tank.
3.3.4Antenna inclination
Ensure the antenna is aligned perpendicular to the product surface (see Figure 3-4). The parabolic antenna comes with a swivel connection that adjusts for angled tank roofs.
Note that if the surface echo is weak in solids applications, then a small inclination of the parabolic antenna toward the surface slope may improve the performance.
Mechanical Installation
Figure 3-4: Inclination
A.Cone antenna/process seal antenna
B.Parabolic antenna
3.3.5Non-metallic tanks
The walls in non-metallic tanks can be invisible to the radar signal, so nearby objects outside the tank may cause disturbing radar echoes. Wherever possible, the transmitter should be positioned so that objects close to the tank are kept outside the signal beam.
3.3.6Beam width and beam angle
The transmitter should be mounted with as few internal structures as possible within the signal beam. Refer to Table 3-3 for beam angle and Table 3-4 for beam width at different distances.

3.3.7Nozzle requirements
In order to allow the microwaves to propagate undisturbed, the nozzle dimensions should be kept within the specified limits as given in Table 3-5, Table 3-6, and Table 3-7.
Nozzle requirements for cone antenna
For best performance, the cone antenna should extend at least 0.4 in. (10 mm) below the nozzle. If required, use the extended cone antenna versions (option code S1 or S2).
However, the antenna can be recessed in smooth nozzles up to 4 ft. (1.2 m). Note that if the inside of the nozzle has irregularities (e.g. due to bad welding, rust, or deposit), then use the extend cone antenna.
