Quick and easy flow measurement with clamp-on ultrasonic transducer
Versatile, easy to use
Use a Greyline PDFM 5.1 Portable Doppler Flow Meter to monitor and balance flow, or to troubleshoot flow problems in full pipes. It is ideal to evaluate system performance and can be installed, calibrated, and startedup in minutes. Use it for projects where a permanent flow meter is not required, or to temporarily replace installed flow transmitters.
Ideal for “difficult” fluids
The PDFM 5.1 ultrasonic sensor is clamped on the outside of a pipe. An acoustic pulse is reflected to the sensor from particles or gases in the flowing liquid. The flow rate of any fluid can be measured as long as it contains air bubbles or solids. It is ideal for wastewater, slurries, sludge, viscous fluids, pulp stock, and abrasives.
With its internal battery, the PDFM 5.1 can be operated all day and then recharged overnight. For continuous use it can be powered by a supplied 110-240 V AC wall plug adapter, or use Sleep Mode to only wake up the meter to take a measurement periodically, extending battery life. A 300,000 point data logger is built-in.
Quick, easy, flow measurements from outside a pipe
Each Greyline PDFM 5.1 comes complete with a rugged watertight carrying case, clamp-on sensor, and stainless steel mounting kit. Use the simple 5-key menu system to select units of measurement and to configure for any pipe diameter 12.5 mm (0.5 in) or larger.
