Descriptions GE Panametrics TransPort PT878GC

GE Panametrics TransPort PT878GC clamp-on gas flow meter from HMA Instrumentation is a highly versatile, self-contained, portable transit-time system with options and accessories to meet a variety of gas flow measurement needs. Its compact size, lightweight, rechargeable battery pack, and universal power supply charger make it the ideal go anywhere flowmeter.

Historically, clamp-on flow metering was limited to liquids because existing methods could not work on metal pipes containing gases. Panametrics developed new technology that extends all the benefits of clamp-on flow metering to gas measurement. This remarkable ultrasonic technology works with gases at high or low pressure in pipes made of metal and most other materials.

GE Panametrics TransPort PT878GC flowmeter can be used to measure the flow of any gas. It is especially useful for metering erosive, corrosive, toxic, high-purity or sterile gases, or in any application where penetrating the pipe wall is undesirable.

Since no tapping or cutting of the pipe is required, permanent installation costs are significantly reduced. The meter has no wetted or moving parts, causes no pressure drop and has very wide rangeability.

Portable Flow Metering at Its Best

The TransPort PT878GC flowmeter is a highly versatile, self-contained, portable transit-time system with options
and accessories to meet a variety of gas flow measurement needs. Its compact size, lightweight, rechargeable battery pack, and universal power supply charger make it the ideal go-anywhere flowmeter.

No Pressure Drop, Low Maintenance

Because the transducers clamp onto the outside of the pipe, they do not obstruct the flow inside the pipe. This prevents the pressure drops typically caused by other types of flowmeters. The TransPort PT878GC has no components that will foul or collect debris, and there are no moving parts to wear out. As a result, it requires no lubrication and little or no routine maintenance.

Advanced Clamp-On Ultrasonic Transducers

One of the biggest challenges in developing clamp-on ultrasonic transducers for gas applications is the difficulty in transmitting a coded ultrasonic signal through a metal pipe wall, through the gas, and then back through the pipe wall to the second transducer that is waiting to receive the signal. In gas systems, only 4.9 x10–7 percent of the transmitted sound energy is actually received by traditional ultrasonic transducers. This simply isn’t enough to produce reliable measurements.

Quick and Easy to Use

It’s possible to make the first flow measurement within minutes of opening the box—the TransPort PT878GC flowmeter is that easy to use. Input the site parameters, clamp the transducers onto the pipe, and adjust the spacing. No ancillary equipment is needed, and there’s no need to break into the pipeline. An experienced user can make scores of different measurements in a single day. The TransPort PT878GC flowmeter is ideal for all kinds of flow survey work.

Built to Be Economical and Stay Economica

To be of real value, a portable flowmeter must be as economical to own and operate as it is capable in the field. The TransPort PT878GC flowmeter is built to stay in service for many years. Completely solid state, the device rarely wears out or needs servicing, resulting in little downtime and low maintenance costs.

Optional Pipe Wall Thickness-Gauge Transducer

Pipe wall thickness is a critical parameter used by the TransPort PT878GC flowmeter for clamp-on flow measurements. The thickness-gauge option allows accurate wall thickness measurement from outside the pipe.
