Ultrasonic gas meters have become the measuring instrument of choice for gas volume measurement in custody transfer because of its superior measuring accuracy, reproducibility, wide measuring range and low maintenance costs.
RMG USM GT400-6P Multipath Ultrasonic Gas Meter is the high-end result of continuous product development of ultrasonic meter technology. Already with the market launch of the first RMG ultrasonic meter in 1999, the principle of 6-path measurement was applied for custody transfer metering. In the current 4th generation, the optimum measuring instrument is available for the precise measurement of large flows at high pressures in pipelines and gas transfer stations. The Virtual Meter Path Technology ™ (VMPT) provides a virtual method of check measurement without adding additional meter components.
Developed and produced in Germany, RMG is recognized as one of the leading providers of gas measurement technology worldwide. With 120+ years of experience, RMG gas meters have been the first choice when it comes to gas flow and volume measurement for their partners.
