SIKA flow monitors monitor the liquid flow of low-viscosity media in pipelines. The SIKA paddle flow monitor VH501 is particularly suitable for oil flow monitoring in traction transformers, e.g. in the electrical industry or in rail transport.

The flowing medium hits the baffle flag attached to the end of a paddle. The paddle is deflected by the resulting dynamic pressure and actuates a micro switch.
