Flow monitor Type VH501

 

Product description

Possible areas of application Flow monitor Type VH501

SIKA flow monitors keep measurement of the flow of low-viscosity liquids in pipelines. Our SIKA VH501 paddle flow switches are particularly suitable for oil flow monitoring for traction transformers e.g. in:

  • the electrical industry or
  • in rail transport.

 

Description

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.
