• Page 12: System Description

  Chapter 1. 1.1.2 System Description The TransPort is only one part of the flowmeter system. The other part of the system is the flowcell, which consists of the pipe and the transducers. 1.1.2.1 The Flowcell The flowcell is that part of the system that uses ultrasonic pulses to interrogate the flow. It consists of the flowcell pipe and the transducers.

• Page 13: Electronics Package

  Chapter 1. 1.1.2.2 Electronics Package The TransPort consists of circuits that generate, receive, and measure the travel time of the ultrasonic pulses. It also contains a microcomputer that controls operation and calculates flow measurement parameters. Specific circuits function as follows: TRANSMIT SIGNAL GENERATOR — The transmit signal generator, under control of the microcomputer and timing circuit, synthesizes the signal that drives the transmitter.

• Page 14: Theory Of Operation

  Chapter 1. 1.1.3 Theory of Operation The TransPort is a transit-time ultrasonic flowmeter. When ultrasonic pulses are transmitted through a moving liquid or gas, the pulses that travel in the same direction as the fluid flow (downstream) travel slightly faster than the pulses that travel against the flow (upstream).

  Pipe Problems Improper pipe conditions and/or flowcell installation can cause problems with measurement of the gas flow. Contact Panametrics Sensing if you cannot solve pipe-related problems. By far, the most common pipe problems are the following THE COLLECTION OF MATERIAL AT THE TRANSDUCER LOCATION(S). Accumulated debris at the transducer location(s) will interfere with transmission of the ultrasound signals.

  If corrosion is suspected, remove the transducer from the flowcell and carefully inspect the electrical connector and the transducer surface for roughness and/or pitting. Any transducer damaged in this manner must be replaced. Contact Panametrics Sensing for information on transducers in materials suitable for the application.

  IrDA compatibility and either a built-in IR port (available on most laptops) or an IR dongle (IR to RS232 adapter for PCs without a built-in IR port). If your PC does not have an IR dongle, Panametrics Sensing recommends the ActiSys ACT-IR220L+ infrared to RS-232 adapter, which has been tested for compatibility with the PT878GC.

  Appendix B. B.1.0.2 Windows NT4.0 For IR use, Windows NT4.0 requires installation of QuickBeam software from Extended Systems (www.extendedsystems.com). Desktop PCs and laptops without built-in IR ports also require adding an IR dongle. While laptops with a built-in IR port normally do not require a dongle, its addition might be necessary in some cases. B.1.0.3 Windows Me/98SE/98/95 The Windows 98SE and Me operating systems include IR drivers.

• Page 209: Ultrasonic Thickness Gauge Theory Of Operation

  Appendix C. Appendix C. Ultrasonic Thickness Gauge Theory of Operation All ultrasonic thickness gauging involves timing the round trip of a sound pulse in a test material. Because solid metal has an acoustic impedance that differs from that of gases, liquids, or corrosion products such as scale or rust, the sound pulse will reflect from the far surface of the remaining metal.

  Appendix C. Transducer Figure 171: Proper Alignment of Transducers for Cylindrical Surfaces While firm hand pressure on the transducer is necessary for good readings, the probe should never be scraped along or twisted against a rough metal surface. This will scratch the face of the transducer and eventually degrade performance.
