This means vortex flowmeters, like electronic turbine meters, each have a particular “k factor”
relating the number of pulses generated per unit volume passed through the meter37. Counting
the total number of pulses over a certain time span yields total fluid volume passed through the
meter over that same time span, making the vortex flowmeter readily adaptable for “totalizing” fluid
volume just like turbine meters. The direct proportion between vortex frequency and volumetric flow
rate also means vortex flowmeters are linear-responding instruments just like turbine flowmeters.
Unlike orifice plates which exhibit a quadratic response, turbine and vortex flowmeters alike enjoy
a wider range (turndown) of flow measurement and do not require special signal characterization to
function properly
