Flow monitor Type VH500


Product description

Possible areas of application Flow monitor Type VH500

SIKA flow monitors keep measurement of the flow of low-viscosity liquids in pipelines. Our SIKA VH500 paddle flow switches are especially suitable for marine applications such as:

  • Cooling water monitoring
  • Lubrication control
  • Monitoring for leaks

in marine engines and compressors..



Paddle principle
The flowing medium hits the plate secured to the end of a paddle. The resulting dynamic pressure causes the paddle to travel. This, in turn, causes the actuation of a micro switch.
