Quick Overview

The PDFM3 is a handheld non-invasive Doppler flowmeter for measuring the flow rate and total volume of liquids flowing through process and effluent pipelines. It is suitable for a wide range of liquids, including aerated water, liquids containing suspended solids, slurries and sludge's. The PDFM3 requires fluids with a minimum concentration of 100 ppm of solids or bubbles having minimum size of 100 microns.

The flowmeter utilises a single clampon sensor and the non-intrusive Doppler principle to measure the mean velocity and is particularly useful as a temporary flow indicator or as a working tool to establish and verify flow conditions in field or plant installations.
