The Panametrics TransPort PT878GC gas flow meter is a highly versatile, self-contained, portable transit-time system with options and accessories to meet a variety of gas flow measurement needs. It is especially useful for metering erosive, corrosive, toxic, high-purity or sterile gases, or for any application where penetrating the pipe wall is undesirable. Since no tapping or cutting of the pipe is required, installation costs are significantly reduced.

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 at high or low pressure in pipes made of metal and most other materials.

The transit-time technique uses a pair of transducers, with each transducer sending and receiving coded ultrasonic signals through the fluid. When the fluid is flowing, signal transit time in the downstream direction is shorter than in the upstream direction; the difference between these transit times is proportional to the flow of velocity. The PT878GC measures this time difference and uses programmed parameters to determine flow rate and direction.
