PDFM6.1 - Portable Doppler Flow Meter

PDFM6.1 – Portable Doppler Flow Meter

The PDFM 6.1 Portable Doppler Flow Meter provides fast, accurate, non-invasive flow measurement for the most challenging industrial environments and mediums. No other clamp-on flow meter is easier to install or operate. Whether you need flow measurement when you didn’t have it before, or you need to prove that your existing system is performing properly, the PDFM 6.1 Portable Doppler Flow Meter is here to simplify the challenging.

With more advanced signal processing, a low-power mode for extended flow logging applications, and a rugged IP67 extruded aluminum enclosure, the PDFM 6.1 is the right choice for your next immediate or long-term flow measurement application for fluids with solids and undissolved gases present, like raw sewage, aerated water, viscous liquids, slurries, and abrasives. No downtime is required.
