Magnetic Flip Level Gauge

I. Structural Features:

Basic level gauge operates based on the buoyancy principle. 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 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 mounted 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 upward and downward movement of the magnetic float, causes the measuring components inside the conduit to act sequentially via magnetic coupling. This produces a change in resistance signal, which is then converted into a standard current signal of 0~10mA or 4~20mA for output, facilitating connection with a digital display instrument or computer to enable remote display.

II. Working Principle:

This product consists of the main body, a flip-top box (comprised of red and white magnetic flip-top switches), a float, a flange cover, and a level transmitter, as illustrated in the diagram. The working principle is as follows: The flip-top box and transmitter outside the main body are actuated by the float inside (equipped with directional magnetic sources, 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. Simultaneously, 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 gently open the valve to allow fluid entry. Then, preheat the special glass tube for 20-30 minutes. Once it reaches a certain temperature, you can fully open both valves to fill with water or other media.

2. Regular drainage is required during use to prevent clogging of passages and false water level phenomena 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: Usage and Maintenance:

1. After packaging, the level gauge can be transported using standard transport methods, but should be avoided from intense vibrations and direct erosion by rain and snow.

2. The level gauge should be placed in a dry and well-ventilated room with a temperature of 0~40°C and relative humidity not exceeding 80%, and outdoor air should not contain corrosive substances for the instrument.

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 for isolation during cleaning and maintenance.

5. Depending on the medium, the main tube should be cleaned regularly to remove any debris inside.
