Technical Field

The utility model belongs to the technical field of the board level gauge is turned over to magnetism, especially relate to a be applied to magnetism of boiling medium operating mode and turn over board level gauge magnetism float.

Background

The magnetic turning plate liquid level meter is a liquid level meter for measuring liquid level by utilizing buoyancy and magnetic force principles, the liquid level meter is connected with equipment through an upper flange and a lower flange, and the gas phase pressure of the liquid level meter is the same as that of the equipment. When the liquid level of the equipment changes, the liquid level in the liquid level meter also changes, the liquid level meter is the same as the liquid level, the turning plate indicator scale is close to the float chamber, the turning plate is attracted by magnetic steel in the magnetic float to turn, the turning part displays red, the non-turning part displays white, and the red-white boundary part is the liquid level. In general, the float is generally made of metal, and the float volume is large in order to enable the float to float in various liquids; in order to prevent the floater from shaking violently, the floater cannot be made too thin, and only a small gap is reserved between the floater and the floater chamber, so that the turning plate for indicating the liquid level cannot turn back and forth frequently.

In the boiling operating mode, the liquid phase can produce a large amount of gas, because float and float chamber clearance is less, gas can not in time get into the gaseous phase from the clearance to gather around the float, gas density is far less than liquid, and the float can not float, thereby can sink and make gas get into the gaseous phase from the narrow and small space between float and the float chamber, because the boiling operating mode can constantly produce gas, the float then constantly sinks, finally can't normally measure the liquid level.
