Portable non-contact flow measurement for the harshest mediums and environments. The simplest to install and 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 help by providing fast, accurate, non-invasive flow measurement in challenging industrial environments and difficult to measure mediums. No other clamp-on flow meter is easier to install and operate.
With 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 challenging flow measurement application. No downtime is required.
Friendliest meter for the unfriendliest applications
The PDFM 6.1 comes equipped with everything you need to install it in just a couple of minutes. There’s no need to configure a pipe material, wall thickness, liner configuration, or fluid characteristics before setting up. Simply clamp the single ultrasonic sensor to the pipe, set the inside pipe diameter in the easy-to-use programming menu, and the meter will immediately report flow when solids or undissolved gasses are present and moving.
Ideal for “difficult” fluids
Where clamp-on transit-time or contacting flow technologies struggle to measure or need increased maintenance because of the presence of solids or gas in the medium, the PDFM 6.1 and its clamp-on Doppler technology won’t. 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 bubbles present.
