All Liquid Level & Flow Sensors |

Our liquid level sensors with integrated magnetic floats and cable terminals are used to detect low fluid levels or multiple fluid points. Choose from vertical or horizontal mount options and a range of switching options. They are simple, dependable, versatile, and low cost. Easily customizable and simple to install, magnetic level sensors are low power devices that don’t require electronics, making them very appealing for most applications. Reed liquid level sensors are fast becoming the level sensing technology of the future. What is driving this is its key reed sensor characteristics. They draw zero voltage and current – no power until they are energized. They can sit for years never drawing any power. This attribute alone allows them to be designed-in, in many applications where power is scarce. This includes many battery driven applications.

FPS-B Series (HVAC/R) Liquid Level Sensor

FPS-B Series (HVAC/R) Liquid Level Sensor bracket model flood prevention switches are simple to install, easy to service and extremely reliable. As water level in the auxiliary or main drain pipe rises (due to a clogged air conditioning condensate drain) the switch shuts off the system, thus preventing water from overflowing, causing damage to floors, walls and ceilings. Ideal in commercial or residential installation to primary or auxiliary condensate drain pans. This model includes a custom bracket that clips onto primary or auxiliary drain pans. UL508, NEC and IMC compliant.

FPS-L Series (HVAC/R) Liquid Level Sensor

FPS-L Series (HVAC/R) Liquid Level Sensor elbow model flood prevention switches are simple to install, easy to service and extremely reliable. As water level in the auxiliary or main drain pipe rises (due to a clogged air conditioning condensate drain) the switch shuts off the system, thus preventing water from overflowing, causing damage to floors, walls and ceilings. Ideal in commercial or residential installation to primary or auxiliary condensate drain plugs. This model includes a custom elbow pipe fitting to accommodate easy installation to primary or auxiliary drain plugs. UL508, NEC and IMC compliant.

FPS-T Series (HVAC/R) Liquid Level Sensor

FPS-T Series (HVAC/R) Liquid Level Sensor tee model flood prevention switches are simple to install, easy to service and extremely reliable. As water level in the auxiliary or main drain pipe rises (due to a clogged air conditioning condensate drain) the switch shuts off the system, thus preventing water from overflowing, causing damage to floors, walls and ceilings. Ideal in commercial or residential installation to primary condensate drains vertical and horizontal, including a close coupled plugged or vertical drain option. Our most versatile plug-n-play model includes two “Do-It-All” custom tee pipe fittings for easy and flexible installation options. UL508, NEC and IMC compliant.
