The liquid inlet of the liquid level measuring instrument (magnetic flap level gauge, differential pressure level gauge) installed on the storage tank is at the bottom of the storage tank and other containers for a long time; because the measured liquid contains microparticles, the deposition of particles will cause the liquid inlet pipeline of the liquid level measuring instrument to be blocked, which will lead to the inability to accurately monitor the pressure, and the liquid level measurement will show deviations or errors, causing safety hazards in the production and operation of storage tanks and other containers. When the liquid inlet is blocked by deposited particles, the common method is to remove the liquid level measuring instrument, clear the pipeline, and then reinstall it for use. The operation process is inconvenient and there are certain safety risks. Utility Model Content
