FM19 & FM29 Offset Multi-Level Liquid Sensor
The FM19/20 offset multilevel liquid level sensors mainly consists of internal magnetic reed switches and up to 4 floats for the FM19 and up to 5 floats for the FM29 model. The offset stem allows for incorporating a multilevel liquid height detection using a side mount configuration. This sensor has designed characteristics such as compact size, simple working principle, highly reliable and inexpensive. The electrical parameters can be changed in accordance with client’s requirement, and special specification can also be customized.

Product Description
When the level of the tank’s liquid rises or falls past the level of the float, the float will rise and fall with it, activating the switch. Wires then send an electric signal to the outside of the tank through the watertight seal, making these components essential for accurate monitoring or regulation of fluid levels in many contexts. Like side-mounted switches, 90 degree mount float switches are mounted through the side of a tank. However, they function as vertically mounted switches, with doughnut-shaped floats rising and falling with the level of the liquid around stems, actuating reed switches inside the stems.
