The SIKA VH501 flow switch monitors the flow of low-viscosity media in pipes. The SIKA VH501 offers a reliable solution for ensuring the minimum flow rate and thereby protecting high-quality systems and installations from damages. These flow switches work based on 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. The flowing medium hits the plate secured to the end of a paddle.
