Product Description

Magnetic Column Liquid Level Gauge

Working Principle:
The UHC series magnetic column level gauge is connected to the vessel through a gas phase and liquid phase connection flange using the principle of a linker. According to the principle of buoyancy and magnetic coupling, the magnetic float in the measuring cylinder (connector) drives the two-color flip on the external display of the measuring cylinder to rise (lower) with the measured liquid level. When the liquid level rises, the magnetic float magnetic float drives the flip column to flip 180°, showing red and green; when the liquid level drops, the magnetic float drives the flip column to rotate 180° in the reverse direction, showing white. The height of the red band (or green band) is the height of the measured liquid level, which achieves the purpose of measuring and displaying the position of the measured liquid (boundary) surface.
Each magnetic flip column has a two-color axially symmetric structure with a spacing of 10 mm between the two magnetic flip columns, with white and red (green) indicating the meteorological and liquid phase portions respectively, and the red (or green) and white junctions are The boundary between the gas phase and the liquid phase. The level gauge measures both the liquid level and the interface of two different density media.

Working principle:

Magnetic liquid level transmitter
It consists of imported reed switch, precision resistor and conversion circuit. When the magnetic flux of the magnetic float in the magnetic flip column level gauge is closed to the reed switch at a certain position, the resistance of the three-wire potentiometer is proportional to the liquid level change, and the change of the liquid level is converted into the 4~20mADC signal by the conversion circuit. Output for detection and transmission of liquid level signals.

Magnetostrictive level sensor
It is a new generation of liquid level sensor with high measurement accuracy. It is stable in performance and is not affected by gas, temperature and pressure changes in the tank. Two-wire 4~20mA (with HART), Modbus and other signal outputs are available.
