For years, Vortex Shedding Technology has been a economical and reliable (no moving parts) way to measure liquids, steam and constant density gas flows. Sierra's Volumetric Vortex product line features an inline version, the Model 220 Innova-Flo® and a unique insertion version, the Model 221 Innova-Flo®. Innova-Flo® the most advanced vortex meter on the market.

Using advanced proprietary Digital Signal Processing (DSP) and "low mass" velocity sensor technology to better differentiate the signal to noise ratio effectively eliminates the two most common problems associated with conventional vortex flow meters: reduced Rangeability and errors caused by pipeline vibrations..Where other vortex meters struggle at lower flows (Reynolds numbers below 20,000), by using constant values for the fluid’s density and viscosity entered into its memory, Innova-Flo® smart electronics automatically corrects for Reynolds numbers down to 5000.Both models use Sierra’s state-of-the-art vortex sensing technology tied into a sophisticated on-board computer. In addition HART communication comes standard at no extra charge. When you need to economically and reliably measure liquid flows, think Innova-Flo®!
