Sierra Instruments' Innova-Mass cryogenic flow meters measure five process variables through one process connection

Sierra Instruments has introduced a cryogenic version of its Innova-Mass multivariable mass vortex flow meter. Using a cryogenic temperature RTD, mass calculations are done with density equations of state for liquid oxygen, nitrogen, argon and CO2. The Innova-Mass Model 240 and Model 241 are designed to measure five process variables (mass flow, volumetric flow, temperature, pressure and density) through one process connection. Because mass flow is directly measured, the Reynolds number can be calculated and the flow profile effects in large pipes can be calculated in real time.
