        Turbine flow sensors of the VTY series have been specially developed for use in potable water series applications. The sensors of the VTY series are used, among other things, for measuring potable water tap quantities. The liquid flowing into the turbine flow sensor is divided into partial jets by the perforated disc. These hit the rotor uniformly and cause it to rotate. The rotor speed is now converted into an electrical pulse signal (frequency): The rotor is equipped with magnets, a Hall effect sensor detects the rotational movement. A frequency signal (square wave signal) which is proportional to the flow is available. Due to the uniform flow to the bearing, the forces largely cancel each other out and wear is reduced to a minimum. The extremely hard bearing materials, sapphire and hard metal, also guarantee an exceptional service life. - low wear and extremely long service life due to high-quality bearings
- virtually no series dispersion due to fixed pulse rate
- insensitive to water hammers
- proven in numerous large series applications
- high measuring accuracy, largely independent of the installation position due to integrated flow straightener
 Series VTY20 - Low wear and extremely long durability due to high quality bearing
- Practically no deviation in mass production due to fixed pulse rate, wide measuring span (up to 1:60),
- High measuring accuracy, mostly independent of fitting position due to integrated flow straightener
