Flow Sensor – Turbotron VT 25 Series
The VT 25 Series turbine flow sensor is designed for flow measurement or dosing applications for liquids, because of the very compact design, the very wide measuring range and the convincing precision of measurements, almost unlimited applications are possible. The extremely hard bearing materials – sapphire and tungsten carbide – also guarantee an exceptionally long endurance.
The liquid flowing into the turbine flow sensor is split into individual jets by the guiding blade, these jets hit the rotor evenly from different directions, setting the rotor in motion. The rotation speed of the rotor is then converted to an electrical pulse signal (frequency), the rotors are fitted with magnets and a Hall effect sensor detects the rotation of the rotor. Given the uniform inflow to the bearing, the forces largely cancel themselves out and wear is reduced to a minimum.
