The magnetic turn-over plate liquid level meter is a measuring device for detecting liquid level of container, and is formed from liquid level tube, magnetic turn-over plate display mechanism, magnetic float, upper connecting tube, lower connecting tube and blow-off tube. When the liquid level in the container to be measured rises and falls, the magnetic float in the liquid level pipe also rises and falls along with the liquid level pipe, the magnetic float controls the magnetic turning plate to turn over through the magnetic coupling principle, when the liquid level rises, the turning plate is changed from white to red, when the liquid level falls, the turning plate is changed from red to white, and the red-white junction of the indicator is the actual height of the liquid level in the container.
The principle of the magnetic turn-over plate level meter for measuring the liquid level of the medium is a constant buoyancy method, the magnetic turn-over plate level meter is selected according to the density of the medium when the type of the magnetic float is selected, the density of the medium is usually deviated from an ideal value in actual use, whether the liquid level displayed by the magnetic float is accurate or not is known through a plurality of tests, if the density of the medium changes, the detected liquid level cannot be influenced, because the magnetic float is in dynamic balance in use, if the density of the medium is higher than a set value, the buoyancy force borne by the magnetic float is increased, and the height of the magnetic float immersed in the medium floats. If the density becomes lower, the magnetic float will float a little bit to form a new balance. The density can not be reduced by a wide margin, otherwise the magnetic float can sink and can not float without generating buoyancy force as large as the self weight, so that the measured value is often inaccurate and needs to be corrected again when the liquid density change changes frequently.
