Possible areas of application
SIKA VTH25 turbine flow sensors are used for flow measurement and dosage in water and water mixtures, and are used in many applications such as:
- Monitoring cooling circuits in machine and plant engineering
- Water treatment
- Cleaning processes
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 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.
The construction of the guiding blade and rotor enables to realize the very low start-up flow values.
