Vortek Instruments Pro-V® M22 are ideal for volumetric or compensated mass flow measurements of most common gases with line sizes from 1/2 inch to 8 inches (DN25 to DN200), temperatures from -330 to 750 Deg F (-200 to 400 deg C), and pressures to ANSI class 900. The multivariable flow-meters utilize three primary sensing elements–a vortex shedding velocity sensor, an RTD temperature sensor, and a solid-state pressure transducer–to measure the mass flow rate of gases, liquids and steam.
