Floating Ball Level Controller The floating ball liquid level controller is composed of floating ball, plug rod, etc. It is installed on the top of the container through the connecting flange, and the floating ball floats on the liquid level according to the principle of equal volume of liquid. When the liquid level of the container changes, the floating ball also moves up and down. Due to the magnetic effect, the dry spring of the floating ball liquid level controller is magnetically attracted to change the liquid level position into an electrical signal, and the actual position of the liquid is digitally displayed through the display instrument, Floating ball liquid level controller to achieve remote detection and control of liquid level.

The researchers used high-performance, high-brightness LED light sources to achieve the desired effect of glare-free illumination surfaces through reflective surface reflections. At present, researchers have developed lighting demonstration equipment using high-reflection aluminum-coated reflective surfaces, and the lighting effect has reached the optical requirements of uniform illumination. This technology can be used to uniformly illuminate vegetables, meat and baked goods, and truly reflect the natural color of food.
In addition, researchers have developed intelligent control devices for LED lighting. Monitor the radiation spectrum of vegetables, meat or baked foods in Western Sydney by sensors. According to the change of the radiation spectrum, the illumination intensity is adjusted in real time to achieve the best illumination effect.
In the next phase, the researchers will focus on how to integrate the above two devices to design a new lighting technology product that combines the above two functions. 
The floating ball liquid level controller is designed according to Archimedes' buoyancy principle. When the liquid level of the container changes, the floating ball also moves up and down. Due to the magnetic effect, the dry reed of the floating ball liquid level controller is magnetically attracted, so that the resistance in the sensor changes linearly, and then the converter converts the change of the resistance value into 4mA ~ 20mA standard DC signal output, Realize the remote detection and control of liquid level.
