Able to measure flow from outside pipe, DFM 5.1 uses doppler signal processing technology and works with difficult liquids, such as wastewater, sludge, slurries, and abrasives, or any liquid with bubbles or suspended solids. Clamp-on ultrasonic sensor mounts on ½ in. ID or larger pipe, and calibration and start-up are facilitated via 5-button keypad. Standard features include backlit display and totalizer, isolated 4–20 mA output, and 6 control relays. Several options are also available.
