[0002] There are three commonly used structures of level gauges for measuring liquid level, interface level and density. The first is the torsion tube type, which drives the sensor through the displacement of the torsion bar; the second is the spring type, which affects the change of elastic force through the change of buoyancy, changes the displacement of the spring, drives the magnet, and outputs the liquid level signal through the cooperation of magnetic coupling and magnetic sensor. This structure is greatly affected by the medium on the spring, and has poor accuracy and repeatability; the third is the shaft seal diaphragm type, which uses the shaft seal diaphragm as the fulcrum, measures the buoyancy through the principle of lever force balance, and thus measures the liquid level. This structure is simple and reliable, has good measurement accuracy and is not costly.
[0003] The electric float level gauge on the market is based on the principle of force balance. It adopts a new electronically controlled sensor structure on the basis of the early float level gauge, combining the sensor and the lever mechanism into one. It can directly measure the buoyancy of the float in the liquid, which effectively solves the influence of static pressure.
