Abstract: Pressure regulators are a major source of noise in gas pipelines. In recent years, continuous optimization of the regulator design has led to a noticeable noise reduction, in particular in the audible range. However, the amount of noise generated at frequencies above the audible range may be problematic for ultrasonic gas flow meters. The reliability and accuracy of the signal transit time detected and thus the quality of the measured value provided by an ultrasonic gas meter are defined by the minimum signal level differential required between the sensor sound pulse to be analyzed and the signal interfering with the sound pulse (the signalto- noise ratio). The spectral distribution of noise and its dependence on the pressure difference and flow rate at the regulator are of particular interest in this paper. Fig. 1 is a general presentation of the situation.
