Magnetic Flip Level Gauge
I. Structural Features:
Basic Level Gauge operates based on the principle of buoyancy. The float inside the measuring tube moves up and down with the liquid level. The magnetic steel inside the float drives the red and white pointer to flip 180 degrees through magnetic coupling. As the liquid level rises, the pointer changes from white to red, and when it falls, it changes from red to white, indicating the liquid level accordingly.
Limit switch output utilizes a magnetic float to move with the liquid level, causing the spring switch installed at the set position of the level gauge's vertical tube to activate, achieving ON-OFF control or alarm.
Install a transmitter on the magnetic float level gauge. The transmitter consists of a sensor and a converter, which, through the up and down movement of the magnetic float, causes the measuring components inside the tube to act sequentially via magnetic coupling. This results in a change in resistance signal, which is then converted into a standard current signal of 0~10mA or 4~20mA for output. This facilitates connection with digital display meters or computers, enabling remote display.
II. Working Principle:
This product consists of the main body, a flip-top box (comprising red and white magnetic flip-top switches), a float, a flange cover, and a level transmitter, with the structure as shown in the figure. The working principle is: The flip-top box and transmitter outside the main body are activated by the float inside (equipped with a directional magnetic source, specifically designed for different media and pressures), causing the flip-top to flip and display red and white colors, indicating different liquid levels as the float moves. At the same time, the level transmitter transmits the liquid level signal to the control center for level indication and control, which can also be centrally monitored via a computer.

Section 6: Instructions for Use
1. When using the water level gauge, first slowly open the valve to fill the liquid, then preheat the glass tube for 20 to 30 minutes. Once it reaches a certain temperature, you can fully open both ends to fill with water or other media.
2. Regular descaling is required during operation to prevent clogging of passages and false water level occurrences due to contamination.
3. In the event of accidental damage to the quartz tube, rotate the plug of the upper and lower plugs 90 degrees using the upper and lower handles of the gauge to prevent the medium inside the container from continuing to leak out. At this point, the damaged part can be replaced.
Section 7: Use and Maintenance:
1. After packaging, the water level gauge can be transported using regular means of transport; however, it should be avoided from剧烈 vibrations and direct exposure to rain or snow.
2. The water level gauge should be placed in a dry, well-ventilated room with temperatures between 0~40°C and relative humidity not exceeding 80%, and outdoor air should not contain any mediums that can corrode the instruments.
3. The level gauge must be installed vertically, with the vertical deviation being less than 3 degrees.
4. A shut-off valve should be installed between the level gauge and the container to isolate the medium for cleaning and maintenance.
5. Depending on the medium, the main tube should be cleaned regularly to remove any debris inside.
