Most of the water tanks of the current sprinklers have no liquid level detection function and can only be viewed manually. Moreover, this kind of water tank is non-transparent and can not directly see the state of the liquid inside. It is easy to find that the water tank is empty and the equipment is still working, leading to equipment damage.

This problem can be solved by installing a liquid level sensor on the water tank to detect the liquid level. The photoelectric liquid level sensor of Energy Point Technology is based on the principle of optical detection, which uses the principle of light refraction in two different media surfaces. It is composed of optical components (infrared emission tube and photosensitive receiver) and transparent prism. When the sensor detects low liquid level, it will give a water shortage signal reminder; When a high liquid level is detected, it will send a signal to prevent overflow or control to stop adding water.

The photoelectric liquid level sensor has simple structure, high detection accuracy, no mechanical moving parts, high sensitivity, debugging and maintenance free. It also has the characteristics of small size, high temperature resistance, corrosion resistance and chemical stability.
