Description

Magnetic flap level gauge with prevent from gathering device Technical Field The utility model belongs to the technical field of liquid level measurement, and particularly relates to a magnetic flap liquid level meter with an anti-self-aggregation device. Background The magnetic flap level meter (also called as magnetic float level meter) is a level meter based on buoyancy principle and magnetic coupling effect, has the characteristics of visual display, high reliability, strong adaptability and the like, and is widely applied to industrial level monitoring. The magnetic flap level gauge has the working principle that when the liquid level in the measured container is lifted, the magnetic floater in the liquid level gauge body tube is lifted. Permanent magnet steel inside the magnetic floater is transmitted to the magnetic turning plate indicator through magnetic coupling to drive the turning plate unit formed by the red and white small turning plates to turn 180 degrees, so that the corresponding liquid level height is displayed. In the actual production process, when the medium to be measured is a self-polymerizing substance such as butadiene, the medium flowing into the liquid level meter body tube is difficult to circulate, is in a static state for a long time, and is easy to self-gather, so that on one hand, the liquid level meter is blocked, the liquid level meter is invalid, the measurement accuracy is affected, and on the other hand, the seed of the medium to be measured enters a linked storage tank, and the danger is caused. If the liquid level meter is detached for cleaning and maintenance, on one hand, the workload of personnel is increased, and on the other hand, if oxygen enters the storage tank due to improper operation, the risk of self-aggregation of the measured medium is increased.
