Description

Technical Field

[0001] The invention relates to the technical field of liquid level measurement, in particular to a float liquid level gauge with a quick-release mechanism. Background Art

[0002] There are three types of liquid level gauge structures commonly used for measuring the liquid level, boundary 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 magnetic steel, 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, with poor accuracy and repeatability; the third is the shaft seal diaphragm type, which uses the shaft seal diaphragm as the fulcrum to measure the buoyancy through the principle of lever force balance, thereby measuring the liquid level. This structure is simple and reliable, with good measurement accuracy and low cost. The electric float level gauge on the market is based on the principle of force balance. On the basis of the early float level gauge, a new electronically controlled sensing structure is adopted to combine the sensor and the lever mechanism into one, which can directly measure the buoyancy of the float in the liquid, and well solve the influence of static pressure.
