How the level gauge works
2011-12-8 8:41:04

根据浮力原理和磁性耦合作用原理工作的 The level gauge works according to the principle of buoyancy and magnetic coupling.


是按阿基米德定理和磁性材料同性相斥,异性相吸的原理研制而成。 The liquid level gauge is developed according to the principle of Archimedes's theorem and magnetic materials with the same repulsion and opposite attracting. According to the above principle, the liquid level change is linearly transmitted to the liquid level indicator. Red is liquid phase and white is gas phase, so as to achieve the purpose of measuring liquid level on site;

It is based on the characteristics of the magnetic steel mentioned above that the converter contacts are actuated according to the given value of the liquid level through the liquid level control switch to achieve the purpose of liquid level control. 'The liquid level control switch is installed at the position required to be controlled by the liquid level. The device is also based on the principle of magnetic induction to linearly change the liquid level.

DC 4 ~ 20mA current signal; remote transmission and matching with secondary instruments to achieve long-range measurement, recording and control of liquid level;

The magnetic column level gauge is connected to the container through gas-phase and liquid-phase connection flanges. According to the principle of buoyancy and magnetic coupling, the magnetic float in the measuring cylinder drives the two-color on the external display of the measuring cylinder with the rise (lower) of the measured liquid level Rotate the column 180 ° to show red (reverse 180 °

Display white) achieves the purpose of measuring and displaying the position of the measured liquid surface. Each magnetic flip column is a two-color axially symmetric structure. The distance between the two magnetic flip columns is 10mm. The gas phase portion and the liquid phase portion are indicated by white and red, respectively.

Represents the gas part, you can also choose the lower red to indicate the liquid part and the upper white to indicate the gas part; the junction between red and white is the boundary between the liquid phase and the gas phase; the level gauge can also be used for the interface measurement of two different density media; The (bottom) mounted magnetic float level gauge is

The on-site instruction part and its auxiliary devices (liquid level control switch and remote transmission device) are composed of two parts. Users can also choose the on-site instruction part separately;


是以浮球为测量元件;通过连杆上磁钢将液位变化传递给现场指示器,使指示醒目地指示出液位的高度。 The top (bottom) mounted magnetic float level meter uses a floating ball as the measuring element; the magnetic steel on the connecting rod transmits the liquid level change to the on-site indicator, so that the indication clearly indicates the height of the liquid level. When the liquid level in the tested container rises, the float in the main pipe of the level gauge also rises.

The permanent magnetic steel in the float is transmitted to the field indicator through magnetic coupling, which drives the red and white flip column to flip 180 °; when the liquid level rises, the flip column changes from white to red, and when the liquid level drops, the flip column is changed by Red turns to white, and the red and white levels of the indicator are the level of the medium in the container.

Actual height and thus level indication!
