The Water Tank Level Sensor is an important part of the water tank level control system. Using a level sensor for the water tank, solenoid valve, control box, liquid level switch and other accessories can effectively form a Water Tank Level control system. Monitor the materials stored in the water tank. Master important data such as its liquid level, reserves, and quality. A reasonable liquid level can ensure the safe, reliable, and efficient operation of the storage tank.

Water Tank Level Sensors for Level Control

According to the principle of tank level measurement:

There are direct liquid level measuring instruments. Differential pressure type liquid level measuring instrument. Buoyancy type liquid level measuring instrument. Electric liquid level measuring instrument. Ultrasonic liquid level measuring instrument. Radar liquid level measuring instrument. Radioactive level measuring instruments, etc. Read more about: Ultrasonic Tank Level Sensors for Tank Level Monitoring

According to the measured medium characteristics:

Commonly used level gauges are heavy-hammer float level gauges. Magnetic flap level gauge. Radar level gauge. Ultrasonic level gauge. Differential pressure level gauge, etc.

The function of the liquid level sensor is to detect the liquid level. The liquid level sensor is widely used in electrical appliances and industrial equipment that require water level control. The liquid level sensor can realize the function of water shortage protection.

Principle of water level sensor:
The water level sensor has a sensor. Transform the sensed water level signal into a current signal.

There are many types of water level sensors, so their specific measurement principles are different.
If you need to learn more. You can refer to:
Differential pressure type liquid level measuring instrument;
Float level measuring instrument;

According to the situation of the tank, different types of water level sensors can be selected to monitor the water level of the water tank. Such as static pressure type liquid level sensor. It can be digitally displayed locally and the liquid level value can be displayed. It can also be output by a 4-20mA signal. Connect the signal to the secondary display instrument to monitor the level of the water tank.

The liquid level switch, as the name implies, is a switch used to control the liquid level. In terms of form, it is mainly divided into contact type and non-contact type.

Non-contact type such as capacitive liquid level switch.

Contact type such as: float type liquid level switch, electrode type liquid level switch, electronic liquid level switch.

The capacitive liquid level switch can also be realized by a contact method.

Water tank level sensor system

Water tank level controller system:

When the water level of the water tank drops to the set lower limit water level value, the liquid level controller sends a command to instruct the pump valve to open the water supply.

When the water level reaches the set upper limit water level value, the controller will issue an instruction to instruct the pump valve to close and stop the water supply.

In the same way, if necessary, the liquid level controller can also instruct the water pump or electric valve to perform the opposite operation.

The main advantages of the water tank level controller:

  1. The water tank liquid level controller is composed of an instrument control box, a liquid level transmitter (immersed transmission probe), and an actuator (such as water pumps, electric valves, solenoid valves, etc.).
  2. The controller instrument adopts a new generation of module circuit, which has stable and reliable performance and no failure.
  3. The liquid level indicator adopts a digital instrument display, which can continuously measure and display the high-precision water (liquid) level value in a timely manner. (0.01m)
  4. The water level of the upper and lower limit start-stop pump valves that need to be controlled by the water tank and pool can be arbitrarily set.
  5. The input type liquid level transmitter has a small volume and high accuracy. It is suitable for measuring any medium that is non-corrosive to 316 stainless steel. It is not limited by the measurement distance.
