Magnetic flap level gauge using the connecting tube principle
2012-1-7 11:03:46


就是就地显示的磁翻板液位计(不带远传)。 Generally, the ordinary magnetic flap liquid level gauge produced by the manufacturer is the magnetic flap liquid level gauge displayed on the spot (without remote transmission). In-situ display magnetic level gauge with intuitive display, eye-catching, wide viewing angle, compact and reasonable structure,

Safe and reliable, no "running, dripping, dripping, leaking" phenomenon, small maintenance, low maintenance costs, etc., and its indication function does not require additional power supply, even if the power supply fails, the liquid level observation will not be affected. Level detection instrument

First we have to understand the accessories of the magnetic flap level gauge. The magnetic flap level gauge accessories include magnetic floats, stainless steel tubes, flip column indicating plates, and flanges.

原理如下:磁翻板液位计根据浮力原理和磁性耦合作用(磁性浮子的磁力)研制而成。 The principle of the magnetic flap liquid level gauge is as follows: The magnetic flap liquid level gauge is developed based on the principle of buoyancy and magnetic coupling (magnetic force of the magnetic float). When the liquid level in the tested container rises or falls, the magnetic float in the tube of the level gauge body

It also moves up and down. The permanent magnetic steel in the float is transmitted to the magnetic flip column indicator through magnetic coupling, which drives the red and white flip columns to turn 180 °. When the liquid level rises, the flip column changes from white to red. Turn column changed from red to

White, the red-white junction of the indicator is the actual height of the liquid level inside the container, so that the liquid level is clearly indicated.


There is a magnetic float inside the magnetic flap liquid level gauge. Why is the height of the liquid level rising from the inner float the measured liquid level?


Because the magnetic flap liquid level gauge uses the principle of communication tube to ensure that the liquid level between the measured container and the measuring tube is equal, when the float in the measuring tube changes with the measured liquid level, the magnetic body in the float and the display board Show magnetism in color bars

Body effect, the color column is reversed, white means no liquid, red means there is liquid, so as to reach the value of the liquid level displayed on the spot.


原理其实很简单,但是就是这个看似简单原理,却能达到很多液位计达不到的效果。 The principle of the magnetic level gauge is actually very simple, but it is this seemingly simple principle that can achieve many effects that the level gauge cannot achieve. Because of this magnetic flap level gauge principle, many magnetic flap level gauges are called or named.

For example, there are magnetic column level gauges and magnetic float level gauges which are the same product.
