USM GT400-3P ultrasonic gas meter
Robust measurement technology for difficult applications
The GT400-3P series gas meter is the result of field-proven direct path measurement and continuous product development of ultrasonic gas meter technology. The RMG ultrasonic meter as a 3-path measurement is specially designed for operational measurements and measurements of gases that are not always pure and can be used as a replacement for orifice meters with considerable advantages. The GT400-3P gas measuring system enables comparatively precise measurement, especially at high flow rates and high pressures.
Due to the pressure-resistant design of the sensor technology, a particularly high sound power is available, which also makes the meter interesting as a 3-path variant for different applications.

High measurement accuracy and reliability for non-custody transfer measurements
Good measuring performance, even with moist gases and raw natural gas
Failure of one measuring path is compensated
Reduced maintenance costs as there are no moving parts
Measurement of gases with up to 30% hydrogen admixture possible
Insensitive to controller noise
Device for measuring gas volume during operation
- High measuring accuracy
- High flow velocity (up to 40 m/s), enabling the use of smaller nominal diameters
- Fully encapsulated, robust and dirt-repellent sensors made of titanium
- Sensor replacement possible without recalibration
- Can be used from atmospheric pressure to high-pressure applications
- Connection to RMG Flow Computer via RS485 / DSfG instance F
- Operation / parameterization via the RMGViewUSM diagnostic software
- NACE MR0175/ISO 15156 compliant
