Tech Note 13 - RMG's GT 400 Gas USM Regulator Noise Immunity Example
By John Lansing, RMG Americas:
Today’s gas USM metering facilities often require using regulators in close proximity for pressure and/or flow control. It is well known that pressure regulators create significant ultrasonic noise inside the pipeline which can interfere with the meter’s operation. When the regulator noise exceeds the meter’s ability to differentiate the receiving signal from the extraneous noise, meter performance will decrease, and it can stop working.
