It is suitable for a wide range of liquids, including aerated water, liquids containing suspended solids, slurries and sludges. The PDFM3 requires fluids with a minimum concentration of 100 ppm of solids or bubbles having minimum size of 100 microns.

PDFM3 portable doppler flow meter’s features: 

  • Non-invasive clampon sensor 
  • Hand held flowmeter 
  • Pipe sizes ≥DN25 
  • Volumetric flow units of measurement 
  • Metric and English units 
  • Easy to use 
  • Flow total and rate display 
  • Long battery life 
  • Data logger option
Portable doppler flow meters utilise 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.
