The Greyline Instruments PDFM 5.1 Doppler flow meter is fast and easy to operate making it ideal for flow troubleshooting, balancing and checking performance of permanent flow meters. The non-contact sensor quickly attaches to the outside of a pipe while the built-in keypad and calibration menu let you set up the instrument in minutes. Use the PDFM 5.1 for projects where a permanent flowmeter is not required or to temporarily replace installed flow transmitters.
The PDFM 5.1 non-intrusive Doppler ultrasonic sensor works with pipes from 1/2" to 180" in diameter. An acoustic pulse is reflected back 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, and most chemicals, acids, caustics, and lubrication fluids. The system works with most metal and plastic pipes including PVC, ductile iron, carbon steel and stainless steel.
The Greyline PDFM 5.1 is AC/DC powered with built-in NiMH batteries and external charger. With its 4-20mA output you can use the PDFM 5.1 as a spare transmitter in critical applications. For flow studies and troubleshooting, use the built-in 300,000 point data logger. Data logs can be retrieved with the data logging software. Simply connect the USB output directly to your PC or Laptop to download data logger files.
