The Portable Series UF Sonicflow Flowmeters are non-invasive "transit time" ultrasonic flowmeters designed to help service/maintenance and commissioning engineers take quick, accurate flow readings. Flow rates up to 26 ft/sec (8 m/sec), of almost any clear or cloudy liquid can be measured with ±2% accuracy. Easy to install flow transducers mount directly to a variety of pipe materials such as stainless steel, cast iron, ductile iron, PVC, copper, and concrete with diameters of 1/2" to 4-1/2" using Model UF10A or 2" to 15.75" using UF35A. UF35A features a 4-20 mA output signal.

Set up is simple using the 15 key tactile membrane. Program flow rate indication in GPM, LPM, ft/sec, or m/s and display total flow in gallons or liters. Flowmeter includes transducer assembly, interconnecting cable, couplant, batteries, universal mains supply, case, and instruction manual. NIST certificate included.
