How to install an electric water tank buoy professionally

How to connect an electric water tank buoy.
How to connect the electric water tank float, in this article we will learn how to connect the electric water tank float, which allows the tank to be filled automatically by operating the water pump, and the goal of this topic is to explain how to connect the electric water tank float and understand how each element used in the connection works .
Electric float function: Also called electric float switch, it is a switch that floats on the surface of the water so that it rises or falls vertically with the rise or fall of the water level.
The electric float switch is used to detect the condition of the water level inside the tank and accordingly its contact points are changed due to the operation or disconnection of the pump, and it can also be used as an indicator or alarm when the water level rises above a certain limit.
Electric float switch terminals:
The key contains three colored terminals (red / blue / black) and each terminal has a name as follows:
The red end or brown: It is called the “normally open” and symbolized by the symbol (NO) and it is not connected in the normal state. The blue end (Blue): It is called the “normally closed” and symbolized by the symbol (NC) and it is connected in The normal state. The black end: It is called the “Common” and is symbolized by the symbol (C), which is the common point between the open (NO) and closed (NC) point.
Explanation of the work of the electric water tank float When the amount of water in the tank is consumed, the electric float moves downward, causing a change in its contact points, which leads to giving the command to connect the contact points to operate the pump. When the tank is filled with water, the electric float goes up due to the high water level inside The tank changes its contact points, and thus the current is disconnected from the contactor coil, causing the power source to be disconnected from the water pump.
