The liquid level indicator is mainly used for indicating the liquid level of the liquid storage tank, in particular to indicating the liquid level of the liquid storage tank in a cold environment; the liquid level indicator can also be used for indicating the liquid level of a liquid storage device which can not be directly contacted with the outside or a high-viscosity liquid, and belongs to the field of liquid level meters.
Background
Magnetic flap level gauges use the principle of a communicating vessel, the level of which is indicated to be consistent with the level of the liquid inside the tank, and are therefore commonly used as on-site level indicators. However, the magnetic turning plate liquid level meter needs to introduce liquid to be measured into a vertical pipe of the liquid level meter through a communicating pipe, the diameter of the vertical pipe is relatively small, and under the condition that the external temperature of the vertical pipe is low, liquid inside the vertical pipe can be frozen to influence liquid level detection and even damage the vertical pipe of the liquid level meter. The magnetic flap liquid level meter used in cold environment needs heat tracing and heat preservation. One side of the magnetic turning plate liquid level meter is a liquid level display surface, so that the integral wrapping and heat preservation are inconvenient, and the heat tracing band can always consume electric energy during operation, thereby causing energy loss. The heat tracing and heat preservation operations are unreliable, so that the hidden danger of icing always exists when the magnetic turning plate is used in a cold environment.
