Innova-MassMulti-Parameter Vortex Mass Flow Meters

The Sierra Instruments’ Series 240 In-Line and the Series 241 Insertion Innova-Mass™ Vortex Flow Meters provide a reliable solution for proc- ess flow measurement. From a single entry point in the pipeline, Innova- Mass meters offer precise measurements of five parameters including mass flow, volumetric flow, temperature, pressure and fluid density. The unique Innova-Mass design reduces fugitive emissions, wiring, startup time and work-force requirements.

Innova-Mass digital electronics allows reconfiguration for most gases, liquids and steam with generous rangeability. The meter outputs a pulse signal for remote totalization and up to three 4-20 mA analog signals for monitoring your choice of the five process variables. The local key- pad/display provides instantaneous flow rate, total flow, temperature, pressure and density in engineering units.

The Sierra Series 240 and 241 Innova-Mass Meters’ simple installation combines with an easy-to-use interface that provides quick set up, long term reliability and accurate mass flow measurement over a wide range of flows, pressures and temperatures.
