Vertical Liquid Level Sensor

Float switch for liquid level sensing

Vertical Liquid Level Sensors, or float switches, are typically mounted through a sealed hole in the top of a tank. The float rises and falls with the level, actuating reed switches according to set parameters. Signals are then sent to trigger an action or process, making these components essential for accurate monitoring in applications such as flood control, industrial automation, robotic lubrication levels, agriculture, marine, HVAC and liquid level monitoring systems.

Where access to the top of a tank is not possible the vertical float sensor can be mounted through the base of the tank, but the sensor must be able to withstand the hydrostatic pressure generated by the full tank. With the mounting point constantly submerged it is critical that applicable sealing methods are taken into account. Switch logic is reversed and float switch construction can be changed to accommodate this.

The sensor is available as either Normally Open, SPDT or Normally Closed with single or multiple switch points in Polypropylene, Nylon, Nitrile Butadine Rubber or Stainless Steel, for harsh environments. They are easy to install and have a compact size, with customizable, mix and match sensor housing, float materials and switch points to suit the target liquid and application. The cable can be supplied as PVC or Teflon with the desired length and connector combination.
