Flow Switches

SIKA flow switches are used for monitoring volume flows. Depending on requirements, these are available for various nominal widths and set-point ranges. The modular approach allows product designs and options to be matched to a wide variety of applications. The broad temperature and pressure ranges, choice of materials and connection options ensure a very high level of versatility.

The flow switches are available in brass or stainless steel for robust Industrial applications, or reinforced fibreglass plastic for cost-effective OEM applications.

The range of flow switches can be co-engineered and tailored to suit specific customer requirements, with special factory-adjusted switching points.




  • Low pressure drop
  • Immediate response
  • High repeatability
  • Set point dependent only on flow, not on pressure or temperature
  • Long-term stable set points, as there is no spring fatigue


  • Heating
  • Industrial cooling circuits
  • Water treatment
