Overview:

UQD intelligent large floating ball liquid level transmitter is an upgraded product of floating ball liquid level transmitter. The transmitter's meter part is separated from the measuring mechanism to improve the explosion-proof level and make the measurement safer and more accurate. It is especially suitable for continuous measurement of the liquid level of hot heavy oil in the refinery (temperature ≤ 450 ° C, pressure ≤ 6.3 MPa), viscous and dirty media, asphalt, grease and other oil products, and flammable, explosive, corrosive media It can be widely used in petroleum, chemical industry, metallurgy, medicine and other industrial fields. It is an ideal level instrument for production process control.


Working principle:

The measuring part of the UQD floating ball liquid level transmitter is composed of a floating ball, a balance rod and a balance weight, which is a torque balancing mechanism, so the floating ball can rise and fall freely as the liquid level changes. When the liquid level changes, the position of the floating ball changes accordingly. The main shaft is driven to rotate by the club. The angular displacement sensor in the controller and the main shaft mesh with the gear to convert the change in the liquid level into a corresponding electrical signal. The electronic circuit inside the device converts this signal into a standard current signal that is proportional to the liquid level change.
