Greyline Instruments PDFM 4.0  Portable Doppler Flow Meter Get Quote
 
Question?

 

 

It's ideal for flow troubleshooting, balancing and checking performance of permanent flow meters. The new PDFM 4.0 is fast and easy to operate – you can mount the sensor on the outside a pipe in less than a minute. Use the built-in keypad and calibration menu to set up the flowmeter for your application. The PDFM 4.0 works on any liquid containing bubbles or solids and is recommended for "difficult liquids" like wastewater, slurries, sludge, chemicals, viscous liquids and abrasives. Measures flow through most metal and plastic pipes including PVC, ductile iron, carbon steel and stainless steel.

The Greyline PDFM 4.0 is AC/DC powered with a built-in battery and charger. With its 4-20mA output you can even use the PDFM 4.0 as a spare transmitter in critical applications. For flow studies and troubleshooting use the built-in 50,000 point Data Logger. Retrieve data logs with 'Greyline Logger' software – included free with each PDFM 4.0. Connect the RS232 output directly to the serial port on your PC or Laptop, or by dial-up connection through modems and phone lines.
