Sierra Vortex Flowmeter

Sierra Instruments' Innova-Mass® Multivariable mass vortex flow meter provides a reading of up to five process parameters from a single entry point in the pipeline. The meter can measure the fluid's velocity, temperature, and pressure and calculate mass flow rate, volumetric flow rate and density. Sensing all process parameters at a single location in one integrated meter greatly improves measurement accuracy and reduces total installed cost. The Innova-Mass Model 240 in-line meters are available in 0.5, 0.75, 1, 1.5, 2, 3, 4, 6 and 8-inch sizes with ANSI or DN16 flanges or wafer flow bodies. The Series 241 insertion meters can be used on pipe sizes from two inches and greater. Optional “hot-tap” hardware including packing gland probe seal, retractor, and isolation valves is also available.

Volumetric or mass flow monitoring of gases, liquids and steam Smart electronics extends range down to a Reynolds number of 5000 Inline (Model 240) & Insertion (Model 241) Designs available Ideal for steam applications Selectable outputs for five process parameters in one integrated meter: —mass flow rate —volumetric flow rate —temperature —pressure —density Field-configurable ranges, alarms, outputs and displays Field configurable via six push buttons or magnet through explosion-proof window

Rangeability up to 30:1 Temperature up to 750° F Pressure up to 1500 psig In-line ( 1/2" to 8") and insertion (into pipes > 2") configurations FMC and ATEX approval Flow computer integrates AGA-8 equations for natural gas Full implementation of HART protocol Optional MODBUS protocol
