Flow switches


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.

Our SIKA flow switches are used for monitoring volume flows. Depending on requirements, these are available for various nominal widths and set-point ranges. Our 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, which is why SIKA flow switches are used in so many areas:

  • Heating
  • Industrial cooling circuits
  • Water treatment
  • Potable water applications

Sika level switches are the easy and reliable solution for monitoring fluid levels. The switches are installed at the side using G¾ or G½ thread sizes. The time-tested float principle and a potential-free contact as the signalling transmitter guarantee a high level of operational safety.

The rising level in the tank forces the float up. Via paddle system, the magnet changes its position relative to Reed contact and actuates it. The repulsion between the two homopolar magnets and supports the buoyancy (Version VK... different). As soon as the level sinks again, the float follows also and the magnbet actuates the Reed contact again
