Measurement is based on a vane wheel rotating at a speed proportional to the flow velocity of the fluid which surrounds it. The rotational speed is virtually independent of density, pressure and temperature of the medium. Vane wheel anemometers can be used in gases and liquids.
Sensing the vane wheel rotation is by a proximity switch which has no braking effect on the vane wheel flow meter. A further proximity switch allows sensing of rotational direction and with it recognition of the +/-direction of flow. Contamination does not influence pulse recognition. A further proximity switch allows sensing of rotational direction and with it recognition of the +/-direction of flow.
Thanks to the lightness of the vane wheel, the rotation speed adjusts to velocity increases in milliseconds in gases and liquids, thus ensuring precise measuring.
Vane wheel flow meters can be adjusted and calibrated at the same frequency, so that flow sensors of the same type are interchangeable without restriction. Vane wheel measuring sensors accurately detect even very slight, bidirectional flow velocities. The measured data is recorded, monitored and evaluated per laptop, so that consumption and leakage in drinking water systems can be rapidly identified.
Höntzsch flow rate measuring instruments offer a wide range of applications in diverse branches of industry. Whether in liquid or gaseous media or at high pressure, vane wheel flow sensors always deliver reliable results. Whether in liquid or gaseous media, at high pressure or high temperatures, vane wheel flow sensors always deliver reliable results. An advantage compared to other measuring methods, is the application in fluids with varying gas compositions. Vane wheel flow meters are also an excellent choice for measuring in demineralised, purified water, as electromagnetic flow meters are suitable only to a limited extent under these conditions.
