SIKA has over 45 years of experience in the manufacture of flow switches for liquids. Our expertise in this field, which distinguishes us from other manufacturers, enables us to manufacture highly innovative products based on a modular concept. We offer flow switches to suit many applications and processes. SIKA is not only a market leader in this field, it has also pioneered the springless design concept. Numerous continuous and qualification tests over periods of up to 16 years testify to the quality of our products. We offer flow switches in different materials to suit specific applications and demands. Whether highly rugged and sturdy of stainless steel for industrial applications or cost-optimised of glass fibre reinforced plastic for OEM applications – our product specialists will be happy to help in finding a solution that best suits your application, both technically and economically. Customised serial versions can be provided with special factory-adjusted switching points.

Main advantages:

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

Flow monitors for insertion installation
SIKA flow switches monitor the flow of low-viscosity media in pipes. They offer a reliable solution for ensuring the minimum flow rate and thereby protecting high-quality systems and installations from damages. These flow switches work on the basis of the well- established mechanical operating principles. Thanks to the different paddle lengths, the switch points of the paddle flow switches can be configured for a wide switching range. 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.
