Vortex-Shedding Meters For Liquid And Liquid/Gas FlowsFlowmeters without moving parts developed as replacements for conventional turbine flowmeters. No maintenance required so meters installed permanently. In vortex-shedding flowmeter, piezoelectric or other suitable transducer probe senses changes of pressure caused by passage of vortices. Electronic circuitry processes pressure-change signals to extract vortex-passage frequency representing rate of flow.
