How Todays Gas Ultrasonic Meter Handles Compressor Pulsations
To date, limited testing has been done to determine the effects pulsation in the gas stream may have on the ultrasonic meter’s accuracy and performance. Some previous testing does show that there may be an impact on accuracy when the frequency of the pulsation is the same as -- or a multiple of -- the sampling frequency of the ultrasonic meter.
