Tech Note 5 - GT400 Gas USM Regulator Performance Significantly Reduces Cost
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. Traditionally many clients install a number of tees between the meter and regulator to help isolate the noise from the meter. This solution significantly increases metering facility cost in several ways.
