Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to liquid level meter technical field more specifically, the utility model relates to a kind of magnetic flap liquid level meter. BACKGROUND
[0002] The working principle of magnetic flap liquid level meter involves Archimedes buoyancy principle, communicating vessel principle and magnetic coupling principle.When the liquid level in the container to be measured rises and falls, the magnetic float in the liquid level meter body pipe also rises and falls, and the permanent magnet steel in the float is transmitted to the magnetic flip column indicator by magnetic coupling, driving the red and white flip column to flip 180°.When the liquid level rises, the flip column changes from white to red;When the liquid level falls, the flip column changes from red to white, and the red and white junction of the indicator is the actual height of the liquid level inside the container, thereby achieving clear indication of the liquid level.
[0003] As a reliable direct-reading liquid level meter, the magnetic flap liquid level meter applied to chemical storage tanks cannot be clearly seen due to the high tank body or dim light at night, therefore, a magnetic flap liquid level meter is urgently needed to solve the above problems. SUMMARY
[0004] In order to overcome the above-mentioned defects of the prior art, the embodiments of the utility model provide a magnetic flap liquid level meter, which is provided with a magnetic float, a reed contact strip and a magnetic plate indicator contact strip, so that the magnetic flap liquid level can be visually observed at any time, and the actual use effect is good, to solve the problems raised in the above background art.
[0005] To achieve the above object, the utility model provides the following technical scheme: a magnetic flap liquid level meter, comprising a main conduit, a magnetic plate indicator is arranged on one side of the top of the main conduit, a magnetic plate indicator contact strip is arranged at the bottom of the magnetic plate indicator, an electromagnetic box is fixedly installed on one side of the main conduit, a liquid crystal display is fixedly installed at the bottom of the main conduit, a reed contact strip is arranged at the top of the liquid crystal display, a magnetic float is arranged in the main conduit, and the cross-sectional shape of the magnetic float is semicircular.
[0006] In a preferred embodiment, the electromagnetic box comprises three 9V batteries.
[0007] The utility model has the following technical effects and advantages:
[0008] The utility model is provided with a magnetic float, a reed contact strip and a magnetic plate indicator contact strip, so that the magnetic flap liquid level can be visually observed at any time, and the actual use effect is good. BRIEF DESCRIPTION OF DRAWINGS
