The turbine suppliers of flow sensors of the product line Turbotron are sensors for flow rate measurement or dosing applications for liquids. Through its especially compact type, its very wide measuring range and its convincing precision of measurement, it has an almost unlimited application.
Function
The liquid flowing into the Turbotron is divided by the guiding blades in four split beams. These hit the rotor from four directions and put it in motion. The uniform loading of bearing specifications from four sides causes the forces to cancel themselves out for the most part and wear is reduced to a minimum.
The extremely hard bearing materials, sapphire and hard metal, ensure in addition an extraordinary life expectancy.
The rotor rotation rate is now converted into an electrical pulse signal (frequency):
VTH and VTP are equipped with rotors which are fitted with magnets. A Hall effect transducer recognizes the rotation of the rotor.
VTI has stainless steel pins in the rotor. An inductive proximity detector detects the rotor rotation.
In both cases, a flow-proportional frequency signal (square wave signal) is available.
