Background

The float level meter is a level measuring instrument designed according to Archimedes' law and magnetic coupling principle, and the instrument can be used for measuring liquid level, interface level and density and is responsible for outputting upper and lower limit alarm signals. The liquid level gauge is specially used for measuring the liquid level in a pressure container and consists of four basic parts, namely a buoy, a spring, a magnetic steel chamber and an indicator.

The principle is that a buoy immersed in a liquid is subjected to a combined action of downward gravity, upward buoyancy and spring force. When these three forces reach equilibrium, the buoy is at rest in a certain position. When the liquid level changes, the buoyancy borne by the buoy correspondingly changes, and the balance state is broken, so that the elastic force changes, namely the spring stretches, and new balance is achieved. The extension and contraction of the spring make the spring and the rigidly connected magnetic steel generate displacement. Thus, the liquid level is indicated by the magnetic sensing element and the transmission device in the indicator. The instrument of the limit switch can realize the alarm function of the liquid level signal.

The existing buoy liquid level meter is characterized in that under the working condition, a buoy is required to bear external high pressure, the current buoy tube is made of a tubular material, the wall thickness of the buoy tube needs to be increased for bearing the high pressure, the weight of the buoy is increased, the phenomenon that the liquid level meter drifts is caused, and therefore the high-pressure-resistant buoy liquid level meter is provided.
