Portable Doppler Flow Meter - PDFM 5.0 - Greyline Instruments - #4

Text version of the page

Ideal for Tough Flow Applications How it Works The PDFM 5.0 works best with difficult liquids in applications that would damage regular flow meters. Because the sensor is mounted on the outside of the pipe, there is no contact with the moving fluid. The ultrasonic sensor straps onto the outside of pipes ½" (12.5 mm) ID or larger and measures flow in common pipe materials: PVC, carbon steel, stainless steel, cast iron, fiberglass, and lined pipes...any pipe that conducts ultrasound. Doppler signals cannot be transmitted through pipe walls which contain air pockets (materials like concrete and wood), or loose insertion liners (with an air gap between the liner and pipe wall). Because the sensor is so easy to install you can test any application and pipe material in a few minutes. The PDFM 5.0 ultrasonic sensor injects high frequency sound through the pipe wall and into the flowing liquid. Gas bubbles or solids suspended in the liquid reflect the ultrasonic signal back to the sensor. When this sound is reflected from moving bubbles or particles it is returned to the sensor at an altered frequency. This frequency shift is called the Doppler effect. The PDFM 5.0 continuously measures the change from it's transmitted frequency to the received frequency to accurately calculate flow. “ ” New PDFM 5.0 Portable Doppler Flow Meter   No Obstruction No Pressure Drop Just Minutes to Install and Calibrate – Contact a Greyline sales representative in your area or phone one of our sales engineers.
