The structure principle of the anti-frost type magnetic flap liquid level gauge is shown in the figure. The body is a communicating pipe body connected to the user container through a flange. An indicator consisting of a flip column is fixed on the outside of the tube. The flip column is composed of red and white colors. The liquid is white before the liquid is pulled up. When the liquid level rises, the magnetic float follows the rise and drives the flip column to rotate 180 degrees through magnetic coupling. Red to red to indicate the liquid level, the red and white boundary level is the height of the liquid level in the container.
A drain valve can be installed below the frost-proof magnetic flap liquid level gauge. When necessary, the drain valve can be opened to remove dirt. The upper part is provided with a drain bolt, which can be loosened to remove air when necessary.
On the side of the tube body of the anti-frost type magnetic flap liquid level gauge, an upper and lower limit alarm can be installed according to the user's needs. There are two types of alarms: (1) XG type alarm: the alarm is equipped with a movable type (normally open) Reed switch. When the float in the main tube rises (falls) with the liquid level to the alarm set point, the magnetic steel in the float will close the reed switch and send out a contact signal. When the float rises (falls), the alarm will leave the alarm. After the point, the signal of that point is automatically cancelled. (2) XJ type alarm device: The alarm device is equipped with an alarm switch driven by magnetic coupling. When the float crosses the upper and lower limit alarm points, the alarm switch will be activated to send a signal to realize the level alarm or control. The alarm switch has a normally open contact and a normally closed contact. And it has a memory function that the liquid level does not eliminate the alarm signal, which plays a very important role in the safe operation in the production process.
On the other side of the anti-frost type magnetic flap liquid level gauge tube, an electric remote transmitter can be installed according to the user's needs to convert the liquid level height into a standard current signal output for the liquid level signal output and liquid supply. The bit signal is transmitted to the secondary instrument for instruction control and detection.
