Greyline DFM 6.1 Doppler Flow Meter
Gaining accurate flow measurement inside a pipe can sometimes be tricky. The Greyline DFM 6.1 Doppler Flow Meter offers clamp-on pipe flow measurement from outside the pipe. Its Doppler technology makes it perfect for 'difficult' liquids, or liquids with suspended solids such as wastewater, slurries, sludge, chemicals, viscous liquids, and abrasives. The non-invasive Doppler flow meter fits any pipe 12.5 mm (0.5 in) inside diameter or larger and clamps on the outside, gaining flow measurement readings without interrupting the process.
The DFM 6.1's easy-to-follow, 5-button menu keypad makes setting up parameters of the flow application quick and easy and works on the majority of pipe materials. The Doppler technology sends a signal through the pipe wall and is reflected off the particles within the liquid, the change in frequency is reflected on the controller in the form of pipe flow measurement.
Use Doppler pipe flow measurement to control flow within a process, protect pumps from no-flow or dry pumping, or for flow proportionate use - you can even use it to test existing equipment to ensure it's still providing accurate pipe flow measurement.
