InnovaSonic 210i UltrasonicPortable Flow Meter

Sierra’s next generation Innova-Sonic 210i ultrasonic flow meter succeeds at delivering portability and expanded functionality at a significantly reduced cost.


The 210i is ideal for precisely measuring a wide range of liquid flows and temperatures. This universal transit-time meter features a pushbutton interface, ergonomic handheld design and a large digital display that significantly simplifies set-up and data collection. 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.

While principally designed for clean liquids, the 210i operates effectively with the minimal quantity of air bubbles or suspended solids found in most industrial applications.

The 210i provides a powerful and extremely user-friendly programming menu that includes instantaneous flow rate, positive total, negative total, net total, velocity, date & time, and daily flow results. Its 1GB SD memory card promises high capacity data logging and a rechargeable lithium-ion battery supports continuous operation for a minimum of 16 hours.

A fully field-portable, lightweight, yet rugged and totally self- contained flow measurement package, the Sierra 210i comes standard with a sturdy and convenient pelican carrying case, non- invasive clamp-on transducers installed into compact mounting racks (magnetic & cable mount), coupling compound and a start-up CD. And it’s easy to use. It sets up in five minutes or less.
