Turbine flow sensor Type VTI15

 

Product description

Possible areas of application
Turbine flow sensor Type VTI 15

SIKA VTI15 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

 

Description

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 stainless steel pins. An inductive proximity switch detects the rotor rotation.
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.
