The water level sensor in the container will feel the water level signal to the controller, the computer in the controller will compare the measured water level signal with the set signal and derive the deviation, and then according to the nature of the deviation, the electric valve to the water supply "open" and "close" instructions to ensure that the container reaches the set water level.
After the completion of the water supply program, the temperature control part of the computer to the supply of heat medium electric valve issued "open" instructions, so the system began to heat the water in the container. The system starts to heat the water in the container, and when it reaches the set temperature.
Controller to issue the order to close the valve, cut off the heat source, the system into the heat preservation state. Programming process to ensure that the system does not reach a safe water level, the control of the heat source of the electric control valve does not open the valve, thus avoiding the loss of heat and the occurrence of accidents.

The development of water level sensors
In the history of the development of solar water heaters, water temperature and water level sensors have been playing a pivotal role in the development of the water heater, water heaters, intelligent, humanized and water temperature and water level sensors are inextricably linked to the water temperature and water level sensors, the water temperature and water level measurement and control instrument is inseparable from the water temperature and water level sensors, water temperature and water level sensors. Water level sensors work stably is a guarantee of intelligent control of the entire water heater.
Water temperature and water level sensor from scratch, from simple to complex, the service life of the short to long, are inseparable from the efforts of solar energy professionals.
Water level sensor applications
1, humidifier, water heater, water dispenser, automatic milk dispenser.
2, printers, inkjet printers, coffee machines, steam microwave ovens.
3, water pumps, bathtubs, toilets, humidifiers, sanitary ware, medical equipment.
4, other electrical appliances and equipment that require liquid level control.
