The buoy immersed in the liquid is subjected to the combined action of downward gravity, upward buoyancy and spring force. When these three forces reach equilibrium, the buoy will stop at a certain position. With the change of liquid level, the buoyancy on the buoy will change accordingly, and the equilibrium condition will be disturbed, causing the change of elastic force, that is, the expansion and contraction of the spring will reach a new balance. The expansion and contraction of the spring causes it to pass through the rigidly connected magnetic steel. Thus, the liquid level is indicated by the magnetic induction element and the actuator in the indicator. The limit switch meter can realize the function of liquid level signal alarm.

According to the principle of displacement measurement, the displacement cylinder suspended on the measuring spring is immersed in the measured liquid and is buoyant upward by Archimedes, and its force is proportional to the mass of the displaced liquid. According to the liquid level and the piston immersion depth, the upward buoyancy changes, and the measuring spring expands accordingly, so as to achieve the measurement result.
The function and working principle of the main components of the float level gauge is that the front of the lever is suspended by the inner piston, which rises and falls with the buoyancy of the medium. This buoyancy acts on the lever. As the rod rotates, one end of the torsion bar presses on the load cell, causing a slight deformation. The sensor of the float level gauge converts the deformation displacement into an electrical signal, and then converts it into a 4 ~ 20mA standard signal output through the signal processing and conversion circuit to carry out the conversion process. From the working principle of the displacement level gauge, it can be seen that the normal working conditions should be that the float is well installed, the torque tube assembly is driven and the lever assembly before the vector changes. The angle is accurate, and the float displacement change should reflect the component of the linear group on the electronic equipment normally and stably. The main purpose of this is to call us at any time if you don't understand something. You can see the contact information when you enter the official website. You can also consult the online staff. Will help everyone to solve some problems of quotation method.
When the liquid level of the float level gauge is lower than the bottom of the float, the buoyancy in the float is zero, the full weight of the ink acts on one end of the lever, the lever is tilted downward under the gravity of the float, and the other end of the lever is supported by the winding hole of the torque tube. Torque is generated in the form of force in the torque tube. At this time, the torque tube holds a large torque. The elastic deformation of the torque tube of the float level gauge produces a counter torque to balance the external moment. The mandrel deforms with the elastic deformation of the roll tube. When the direction is rotated by an angle, the pointer rotates by the same angle. At this time, the digital position indicated by the indicator is zero level.
