Overview and working principle of maglev level gauge

The magnetic float level gauge consists of three parts: float, riser assembly and indicator. The float rises or falls with the change of the liquid level in the riser assembly, and the solenoid valve drives the color of the indicator outside the riser assembly to change (liquid red and gas blue) through magnetic coupling, thereby indicating the height of the liquid level. The liquid level alarm switch is installed at the corresponding alarm position outside the riser assembly. When the float reaches the alarm position with the liquid level, the alarm switch closes and sends out a switch signal; the liquid level remote transmitter is also installed outside the riser assembly. The solenoid valve linearly converts the change of the liquid level into a 4-20mA current signal through magnetic coupling and transmits it to the control room to realize the display, measurement, control and recording of the liquid level.

　　 Because of the double-layer casing structure and different anti-frost plates according to the temperature of the low temperature medium, it is especially suitable for the liquid level indicator measurement of the low temperature medium.

　　 The principle of FGD series top-mounted magnetic float level gauge

　　□Overview Magnetic float type liquid level gauge

　　 FGD series top-mounted magnetic float level gauge, using the principle of buoyancy and magnetic coupling, the high temperature solenoid valve linearly transmits the change of the liquid level to the indicator, clearly indicating the height of the liquid level. The indicator and the storage tank are completely isolated, so it is safe to use. The liquid level gauge can also be equipped with a liquid level alarm switch and a liquid level remote transmitter. Liquid level alarm switch can realize liquid level up and down control, limit alarm and interlock; liquid level remote transmitter can linearly convert liquid level change into DC 4-20mA output, realize remote liquid level indication, detection and control And record.

The float rises or falls with the change of liquid level in the riser assembly, and the magnetic flip The column level gauge drives the indicator color outside the riser assembly to change (liquid red and gas blue) through magnetic coupling, thereby indicating the height of the liquid level. The liquid level alarm switch is installed at the corresponding alarm position outside the riser assembly. When the float reaches the alarm position with the liquid level, the electric actuator alarm switch closes and sends out a switch signal; the liquid level remote transmitter is also installed on the riser assembly Externally, the change of the liquid level is linearly converted into a 4-20mA current signal through the magnetic coupling and transmitted to the control room to realize the display, measurement, and measurement of the liquid level.
