產品特點產品規格

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.
