Sierra Instruments” updated Innova-Sonic 210i portable transit-time flowmeter features a high-powered ultrasonic pulse with improved digital signal processing, thereby enabling the unit to use just one set of transducers over a wide range of pipe sizes. The meter also includes a new tactile pushbutton interface with a large digital display. The comes with a fully field-configurable 4-20mA current loop analog output, 2GB SD memory card for data logging, and a suite of user-friendly programming menus that simplify data analysis. Complex totalization functions are standard, including parallel operation of positive, negative and net flow totalizers. The meter provides accuracy of +/-1.0 percent of reading, a wide operating temperature range of -40 F to 176 F (-40 C to 80 C) and a bi-directional flow range of 0 to 40f/s liquids (0 to 12m/s). The meter supports pipe sizes from one-inch to 48-inch (25mm to1,200mm). The built-in totalizers record daily, monthly and yearly totalized flow, up to five years.
