The new DFM 5.0 Doppler Flow Meter from Greyline Instruments (Massena, NY) measures flow from outside a pipe. The clamp-on ultrasonic sensor mounts on any pipe ½-inc ID or larger. The DFM 5.0 is designed for “difficult” liquids like wastewater, sludge, slurries, abrasives, or any liquid with bubbles or suspended solids, says the company. Calibration and start-up is simple with the built-in 5-button keypad. Standard features include a large, backlit display and totalizer, isolated 4-20mA output and 2 control relays. Options include a built-in data logger and reporting system with USB output, Windows software, and intrinsically safe sensor.
