Description
PORTABLE ULTRASONIC GAS FLOW METER
The Panametrics TransPort PT878GC brings clamp-on ultrasonic gas flow metering capability to the portable level. Designed for short-term flow survey work for natural gas pipelines, 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.

Flow Range
|
Velocity dependant
|
|
Accuracy
|
– For pipes 6 in (150 mm) and smaller: ±2% to 5% of reading typical
– For pipes over 6 in (150 mm): ±1% to 2% of reading typical
Accuracy depends on pipe size and other factors.

|
Repeatability
|
±0.2% to 0.5% of reading
|
|
Pipe Size Ranges
|
– 0.75 to 12 in (20 to 300 mm) with
TransPort PT878GC-01 electronics
– 4 to 24 in (100 to 610 mm) and larger with TransPort PT878GC-02 electronics
