In some level sensing scenarios, a trusty float switch simply won’t work.

Featured application: Car Washes

Liquid level sensors are critical components in every automatic car wash, and many Madison float switches are working to keep car washes operating today.

Recommended sensor materials for chlorine

Pool and sanitizer system customers often select polypropylene for use in chlorinated systems, but we recommend another material.

Safe Underground Gas Storage with the M3769 Interstitial Float Switch

Have you noticed a lot of gas stations digging up their underground storage tanks recently? We sure have, and the reason is simple: underground storage tanks (USTs) must be replaced periodically for safety reasons. Spills, leaks and fires are real risks, and even a minor leak can cause major harm to people, property, and the environment. Steel tanks are particularly prone to corrosion. Therefore, the EPA closely regulates the installation, maintenance and replacement of approximately 544,000 USTs nationwide.

Simplifying oil/water separation with new switches

Two new Madison liquid level sensors have been developed to reliably detect the interface where oil water and water meet. The key is special specific gravity floats, available in stainless steel and Buna-N.


New Continuous Level Sensor Kits

Madison’s CK Series kits combine a continuous liquid level sensor paired with a pre-programmed panel meter display. Each kit offers a turn-key solution for critical tank measurement and process control. In addition to a sensor and panel meter, each kit contains two relays set at 10% and 90%.
