Product Description
The magnetic flap level gauge is widely used for level measurement
and control in industries such as power,petroleum, chemical,
metallurgy, environmental protection, shipping, construction, and
food. The product operates based on the buoyancy principle and
magnetic coupling. When the liquid level in the measured container
rises or falls, the magnetic float in the gauge's main tube follows
suit. The permanent magnet in the float couples magnetically to the
magnetic flap indicator, driving the red and white flaps to rotate
180°. As the level rises, the flaps change from white to red; as it
falls, they change from red to white. The red-white boundary on the
indicator shows the actual liquid level inside the container,
providing clear level indication. The product offers high sealing,
leak prevention, and safe, reliable level measurement under high
temperature, high pressure, high viscosity, and strong corrosion
conditions.
Product Features
It provides full-range measurement without blind spots, with clear,
intuitive display and large measurement range. Equipped with level
alarm or control switches, it enables upper/lower limit alarms and
control for level or interface. When equipped with a level
transmitter, it can convert the level or interface signal into a
two-wire 4–20 mA DC standard signal for remote detection,
indication, recording, and control.
