The new DFM 5.0 Doppler Flow Meter from Greyline Instruments measures flow from outside a pipe. The clamp-on ultrasonic sensor mounts on any pipe 12.5mm 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. 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 and Windows software and intrinsically safe sensor.
