The flowing fluid maintains in rotation the five blades rotor.
Each blade has a built-in magnet, not in contact with the fluid.
The magnetic field variation induces a pulsating signal with its frequency proportional to the fluid speed.
Our sensor emits a signal frequency about 38 to 45 Hz/m/s (depending of process parameters).
This measurement method assures an excellent response with flow velocity (the minimal flow velocity is 0.8 m/s).
The flow could be loaded up to 2% of non magnetic particles.
The fluid viscosity value should be between 0.5 to 20 cSt at process temperature, otherwise a calibration on site is necessary.
Flow sensor and installation fittings are available for pipes from DN 15 to DN 600, in stainless steel, PVC, PPH and PVDF.
Te fittings are available from DN 15 to DN 50, and collars from DN 40 to DN100.
Weld on adaptors in stainless steel are convenient from DN 50 to DN 600; same figures for glued or polyfusion adaptors proposed in PVC, PPH and PVDF.
The sensor works in any position and on both flow directions.
It is necessary to respect pipe straight lengths upstream and downstream in order to avoid turbulences.
