The Greyline Instruments PDFM 6.1 Doppler Flow Meter provides fast, accurate, non-invasive flow measurement for the most challenging industrial environments and mediums. Designed for for fluids with solids and undissolved gases present, like raw sewage, aerated water, viscous liquids, slurries, and abrasives. By measuring the frequency shift of ultrasonic echoes reflecting off the solids or gas from outside the pipe, the meter can determine the velocity without contacting the medium. The flow rate of any fluid can be measured as long as there are solids or air bubbles present.
Features more advanced signal processing, a low-power mode for extended flow logging applications, and a rugged IP67 extruded aluminum enclosure. The extruded aluminum enclosure with protective covers guard the PDFM 6.1 against damage from falls or impacts that can occur when using the meter in real-world applications. The meter is ready for use outside thanks to IP67-rated connectors and a bright LCD display which makes seeing the screen easy even in the brightest environments.
Each PDFM 6.1 Portable Doppler Flow Meter comes in a rugged PELICAN(TM) case, along with a clamp-on sensor, and stainless-steel mounting kit. Use it for projects where a permanent flow meter is not required, to temporarily replace installed meters that have failed, or to verify output on an existing meter.
