Possible areas of application
Turbine flow sensors of the series VTY were specially developed for the use in potable water mass production applications.
Sensors of the series VTY are used among others for the measurement of tap water.
The liquid flowing into the turbine flow sensor is split into individual jets by the flow straightener. These jets hit the rotor evenly, setting the rotor in motion. The rotation speed of the rotor is then converted to an electrical pulse signal (frequency): The rotor is fitted with magnets and a Hall effect sensor detects the rotation of the rotor.
A flow-proportional frequency signal (square-wave signal) is made available.
Given the uniform inflow to the bearing, the forces largely cancel themselves out and wear is reduced to a minimum. The extremely hard bearing materials - sapphire and hard metal - also guarantee an exceptionally long endurance.
- 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)
- Insensitive against water hammers
- Proven in numerous mass production applications
- High measuring accuracy, mostly independent of fitting position due to integrated flow straightener
