Mass and volumetric vortex flow meter with temperature, pressure and fluid density measurement
RS485, min. -200 °C Sierra Instruments

Sierra was the first to introduce a Multivariable Mass Vortex Flow Meter to the market in the late 1990's. Learn more about how this next generation of Mass Vortex Flow Meter technology came about. Sierra's Multivariable product line features an inline version, the Model 240 Innova-Mass® vortex flowmeter and a unique immersion version, the Model 241 Innova-Mass®. The Model 241 has emerged recently as the proven instrument of choice in geothermal steam applications across the globe. The Model 240 and Model 241 can measure the mass flow rate of any gas or liquid and are ideally suited for saturated or superheated steam. The Model 241 vortex flow meter is available in high-pressure versions capable of mass flow measurement of gases up to 5000 psig.

Our Multivariable Technology allows one instrument and one process connection to measure FIVE process parameters at the same time to simultaneously measure mass flow rate, temperature, pressure, volumetric flow rate, and fluid density.

The Innova-Mass cryogenic version has undergone extensive testing and field validation over the last several years proving that the meter is preferred versus traditional turbine meters for measuring mass flow rates of cryogenic fluids down to -328°F (-200°C).
