This paper presents a compact arbitrary pressure pulsation generator for assessing the characteristics of flow meters and sensors, particularly around their zero points. In this study, a compact arbitrary pressure pulsation generator was created using some pneumatic components, such as a high-precision quick-response pneumatic pressure regulator (HPR) and a spool-type servo-valve. The feed-forward compensation of the controller provided the desired pressure pulse to the tested flow meter by controlling the spool-type servo valve; 30 Hz was achieved.

In order to validate the effectiveness of the developed generator, we evaluated the dynamic characteristics around the zero point of an orifice-type flow meter in the range from 1 Hz through 30 Hz.
