TransPort PT878GC


The TransPort PT878GC is a portable, clamp-on ultrasonic gas flow meter. Designed for short-term flow survey work for natural gas pipeline, compressed air, inert gas or any compressed gas applications, it has the ability to measure gas flow rates, log data to internal memory and export flow data to a PC. It is especially useful for metering of erosive, corrosive, toxic, high-purity or sterile gases or in any application where penetrating the pipe wall is undesirable.

Features and Benefits

• Installation in just minutes

• No need for shutdowns or interrupting the process because no tapping

or cutting of pipe wall is required

• Non-invasive clamp-on transducers

• Temperatures up to 230°C

• Velocity, volumetric, totalized actual and standard flow

• 3/4 to 24-inch pipe size capability

• Built-in datalogger for 100,000 measurements

• Built-in ultrasonic pipe thickness gage (optional)


The TransPort PT878GC portable gas flow meter is a complete ultrasonic flow metering system for measurement of most gases, including:

• Natural gas

• Compressed air

• Fuel gases

• Erosive gases

• Corrosive gases

• Toxic gases

• High-purity gases

• Air separation gases

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.

Historically, clamp-on flow metering was limited to liquids because existing methods could not work on metal pipes containing gases. GE 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.

The 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.

The new meter was tested extensively on metal pipes with diameters as small as 0.75 inches (20 mm) and as large as 24 inches (600 mm). This meter is suitable for measuring the flow of air, hydrogen, natural gas and many other gases.
