Greyline's new DFM 5.1 Doppler Flow Meter employs the latest technology in Doppler signal processing to measure flow from outside a pipe. Faster, cleaner processing, greater data resolution and an improved ability to filter out noise all combine to produce data accuracy far greater than previously possible, Greyline says.
The clamp-on ultrasonic sensor mounts on any ½-inch ID or larger pipe. The DFM 5.1 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 five-button keypad. Standard features include a large, backlit display and totalizer, isolated 4-20mA output and 6 control relays. Options include a built-in data logger and reporting system with USB output, Windows software and intrinsically safe sensor.
