The Greyline PDFM 5.1 Portable Doppler Flow Meter works on any liquid containing bubbles or solids and is recommended for "difficult liquids" like wastewater, slurries, sludge, chemicals, viscous liquids, and abrasives. Ideal for flow troubleshooting, balancing, and checking the performance of permanent flow meters. Fast and easy to operate – you can mount the sensor on the outside of a pipe in less than a minute. Use the built-in keypad and calibration menu to set up the flow meter for your application.
The Greyline PDFM 5.1 is AC/DC powered with built-in NiMH batteries and an external charger. With its 4-20 mA output, you can use the Greyline PDFM 5.1 as a spare transmitter in critical applications. For flow studies and troubleshooting use the built-in 300,000 point Data Logger. Retrieve data logs with 'Greyline Logger' software – included free with each Greyline PDFM 5.1.
