Uf 821

The Uf 821 flow meter is used to measure the flow of liquids in full pipe up to a diameter of 10,000 mm. Configurable via USB port, it is available in single and multi pipe versions and can integrate up to 4 measurement chords. It comes with an LCD graphic display and measurement validation indicators. Equipped with a multi-variable data-logger and maths functions generator, it can also receive optional input/out modules (analogue, digital, temperature, etc.). The Uf 821 takes into account the different flow regimes by Reynolds number calculation.

Nature of equipment

Fixed flow meter

Standard mounted inputs/outputs

Optional inputs/outputs

Up to 4 modules to choose from:

  • 1 isolated, active analogue output: current 4-20mA, 0-20mA, 0-24mA,
  • 2 static relay outputs usable as frequency outputs (up to 1kHz),
  • 2 isolated, passive current inputs 4-20mA, 0-20mA, 0-24mA,
  • 2 isolated, passive analogue 0-10V inputs: 0 to 15V voltage,
  • 2 PT100/PT1000 temperature inputs – taking up the physical space of 2 modules,
  • 2 contact 5V inputs (pulse or state).
