Turbine flow sensor Type VTP15


Product description

Possible areas of application Turbine flow sensor Type VTP 15

SIKA VTP15 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
  • Dosing



Measuring principle
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.
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.
