InnovaSonic 210i – Sierra Portable Clamp-On Ultrasonic Flow Meter

Portable Clamp-On Ultrasonic Flow Meter for High Accuracy Liquid Metering


The InnovaSonic® 210i portable ultrasonic flow meter succeeds at delivering expanded functionality and field portability when a permanent installation is not required.  The 210 is a complete liquid measurement kit with portable clamp-on transducers featuring a small handheld display interface with bright color display and push buttons. While principally designed for clean liquids, the 210 portable meter will operate effectively with the minimal quantity of air bubbles or suspended solids found in most industrial applications. Its high-powered ultrasonic pulse with improved digital signal processing requires just one set of transducers for a wide range of pipe sizes and materials including metal, plastic and concrete.

The handheld battery powered 210 is ideal for precisely measuring a wide range of liquid flows in pipes up to 236 inches (6000 mm).

Utilising universal transit-time technology the 210 portable, hand-held flow meter measures the time it takes an ultrasonic signal to travel a known distance with the flow stream and another signal travelling against the flow stream, determining the velocity of the fluid being measured. The 210 measurement is independent of fluid conductivity to allow a wider applicability compared to magnetic meters.
