Sierra Instruments’ next-generation Innova-Sonic 210i is a universal transit-time flow meter for liquid flow measurement applications. The Innova-Sonic 210i features an ultrasonic pulse with improved digital signal processing, enabling the unit to use just one set of transducers over a wide range of pipe sizes. The 210i also includes a new tactile pushbutton interface with a large digital display designed to simplify set-up and data collection.

Sierra’s Innova-Sonic 210i comes with a fully field-configurable 4-20mA current loop analog output, 2GB SD memory card for data logging, and a suite of programming menus. Complex totalization functions are standard, including parallel operation of positive, negative and net flow totalizers.  

The Innova-Sonic 210i portable also includes clamp-on transducers with magnetic racks (chain straps are included for non-magnetic pipes). An 11 VDC lithium-ion battery and charger are included. Everything necessary for making the measurement (meter, transducers, mounting rack, coupling compound) is packaged in a pelican carrying case for easy transport.

The Innova-Sonic portable features an accuracy of +/-1.0% of reading, an operating temperature range of  -40 degrees Fahrenheit to 176 degrees Fahrenheit (-40 degrees Celsius to 80 degrees Celsius) and a bidirectional flow range of 0 to 40f/s liquids (0 to 12m/s). The flow meter can be used for a wide range of pipe sizes from 1 inch to 48 inches (25 mm to 1,200 mm). The built-in totalizers record daily, monthly and yearly totalized flow.
