Detection of liquid flow in pipes is an important independent measurement to verify control gear such as valves and pumps are operating correctly upstream.
These modules are designed to operate in the audio spectrum and therefore detect audible 'trickles' caused by irregularities in the pipe system. The noisier areas of tubing are generally downstream from unions, joints, valves or even bends. Any flow that is turbulent or partially filled also has good monitoring characteristics for this sensing method.
