High Low Water Level Sensor Switch
A Water Level Sensor Switch, commonly known as a float switch, is a device used to detect the water level in a tank or other container. The “20 to 200mmW.C.” specification you mentioned likely refers to the pressure range in millimeters of the water column that the sensor can detect.
“20mmW.C.” refers to the minimum water column height at which the switch will trigger its low-level signal. In other words, when the water level in the tank drops to 20mm or lower, the switch will activate and send a low-level signal, indicating that the water level is too low.
“200mmW.C.” refers to the maximum water column height at which the switch will trigger its high-level signal. When the water level in the tank rises to 200mm or higher, the switch will activate and send a high-level signal, indicating that the water level has reached the desired upper limit.
These types of switches are commonly used in various applications, such as sump pumps, wastewater treatment systems, and industrial tanks, to control the filling and draining of liquids within a specific range. The switch typically consists of a float that moves with the liquid level and activates a switch mechanism as it reaches the specified low or high point.
How the high and low water level sensor switch works
A high and low water level sensor switch is a device used to monitor liquid water levels, often used to control the filling and emptying of liquid containers to ensure that the water level is maintained within a specific range. These sensor switches can be used in a variety of applications such as water tanks, caissons, flumes, swimming pools, water treatment systems, and more.
These high and low water level sensor switches are usually connected to the control system to trigger alarms, and close or open valves, pumps, or other equipment when the water level reaches set upper and lower limits. In this way, they help ensure that water levels are maintained within safe limits to prevent problems such as overflowing or drying out.

Immersion sensor
This type of sensor is typically made of metal, plastic, or other electrically insulating materials. They are designed to be immersed in liquids while maintaining electrical insulating properties. Sensors usually consist of two or more electrodes located at different heights of the water level. When the liquid level comes into contact with the electrodes, the circuit is closed or opened.
-
Conductivity sensor
A common type of high and low water level sensor uses the conductivity of a liquid to detect changes in water level. As the liquid level rises, the conductivity between the water and the electrode increases, closing the circuit. When the water level drops, the conductivity decreases, and the circuit breaks.
-
Float switch
Another common type of high and low water level sensor is the float switch. This sensor consists of a float that moves as the liquid level rises and falls. The switching device associated with the float may be a magnetic switch, capacitive sensor, or other type of switch. When the liquid level rises to a certain predetermined level, the float rises and triggers the switch to close, and vice versa.

Pressure sensor
In some applications, pressure sensors can be used to monitor liquid levels. When the liquid level increases, the pressure of the liquid also increases, and the pressure sensor can detect this change and generate a corresponding signal.
Function of high and low water level sensor switch
The high and low water level sensor switch is a device used to monitor liquid water levels. It can trigger a switch action when the liquid water level reaches a predetermined high water level or low water level, thereby controlling related equipment or systems.

Prevent overflow or depletion
High and low water level sensors are usually used to prevent liquids from overflowing or drying up and can maintain liquids within a safe water level by controlling pumps or valves. These sensors can also be used to monitor liquid levels and trigger alarms to notify operators or automated systems to take necessary action, such as adding water or stopping the flow, to maintain proper water levels.
Overview of high and low water level sensor switches
A high and low water level sensor switch is a device used to monitor the level of liquids and is primarily used in industrial and household applications. High and low-water-level sensor switches use different sensing principles to detect liquid levels. Common sensing principles include float measurement, electrode sensing, ultrasonic ranging, resistance liquid level sensing, etc. Each principle has its own unique way of working and applications.
The sensor works based on preset high and low water marks. When the liquid level reaches the high-water mark, the sensor typically triggers a switch, causing associated actions such as closing a valve or stopping a pump. When the water level drops to the low water mark, the sensor triggers the switch again, operating in reverse.
High and low water level sensors can typically be installed at various locations in liquid containers or pipes, depending on the range of water levels that need to be monitored and the application. Sensors can be embedded in the vessel wall, fixed on a bracket, or floating on the liquid surface, depending on the sensing principle and specific circumstances.
High and low-water-level sensor switches are widely used in a variety of applications, including water treatment systems, sewage treatment, oil field extraction, food processing, household washing machines, dishwashers, water tanks, sinks, etc. They help ensure that liquid levels are within safe limits and automatically control the operation of related equipment.
