The liquid you’re measuring drives nearly every material decision on the Float Switch. A bad spec leads to premature failure, process contamination, or both. A good spec runs for years
Mounting location directly affects switch performance. An incorrect placement can result in missed set points, restricted float travel, or a configuration that physically cannot be installed in the available space.
Float switches are a straightforward way to control a pump or valve for fill and drain applications. Getting the configuration right comes down to a few key decisions before you
Float switches are one of the simplest and most reliable ways to monitor and control liquid levels in tanks, sumps, and vessels. Whether you’re protecting your basement from flooding, automating
The pulp and paper mill industries use a lot of water in their manufacturing processes and generate huge amounts of wastewater in the process.
Harvesting rainwater is becoming increasingly more important, especially in areas of drought.
Liquid level sensors or float switches are used to monitor liquid levels in tanks or other vessels and are designed to react according to predefined level heights, both high and
