Electrode Holder – Selection of the holder will depend on the environment of the watertank and the installation environment. Typically there are 3 different models (PS-3S, PS-4S, PS-5S) to consider.

Electrodes – 3 types of Electroes are available (standard, underwater and Electrode bands). F03-01 and F03-06 are 2 models widely used in water supply control at watertank.

What is Floatless Level Switch?

Traditional water level switch uses float to detect the level of the water, just like our toilet flushing system. Floatless Level Switch uses electrodes to detect the water level. The controller is then signal automatically to operate the pump, and bring the water to the receiving watetank.

Application of Floatless Level Switch

Typical application of Floatless Level Switch can be used to control the water supply at the ground level transfer tank, as well as rooftop watertanks. Our estate has been using the OMRON Floatless Level Controller since 1997. From 2019 to 1997, it has been 22 years from the time the water tanks was constructed and the control panel installed with the controllers.

 

Water Supply Control using Floatless Level Switch

Using Floatless Level Switch can help to control the water supply effectively. The level switch will detect the level of water in the water tank and provide the signal to the relevant relays and contactor at the control panel.

The sensing of the water level is done by the electrodes installed inside the water tank. The circuit is closed when sufficient water is present, allowing the electricity to flow through.

 

Pump Control with Contactor and Relay Unit

The contactor is connected to the pump and it control when the pump will be activated. Contactor can handle larger current and more complex control functionality.

There are 2 types of contactors: NO Normally Open contactor and it will close when the switch is activated; and the other type of contactor is NC Normally Closed contactor and it will open when the switch is activated.
