Top-mounted magnetic flap level gauge

1. Functions and Scope of Application

The UHZ top-mounted magnetic flap level gauge uses a float assembly as the measurement element. Through the effect of liquid buoyancy, the float moves up and down, causing the magnet at the upper end of the push rod to move up and down. Through magnetic coupling, the magnetic flip column of the display module flips to track changes in liquid level, making the display eye-catching and the readings intuitive. Since the display component is completely isolated from the measured medium, it is reliable to use. This level meter is suitable for various underground tanks and other containers, as well as for containers where side openings are not suitable. When paired with a matching instrument, it can be used for remote detection to achieve automatic control functions.

2. Working Principle

It is made based on the principles of buoyancy and magnetic coupling. When the liquid level inside the container fluctuates, it drives the float ball, which moves up and down through the magnet at the upper end of the connected rod, and through magnetic coupling, causes the flipping column in the display to flip. When the liquid level rises, the flip column changes from white to red. When the liquid level drops, the turning column changes from red to white. The red-white boundary represents the actual height of the medium liquid level inside the container, enabling automatic liquid level tracking and display.

3. Features

1. When the container is not suitable for opening holes from the side and there is little space around the container, this type of level gauge can be arranged at the top or bottom of the container.
 2. Suitable for liquid media with high viscosity.
 3. The viewing direction of the display can be changed arbitrarily

4. Main Technical Parameters

1. Measurement range: 500-5000mm
 2. Measurement accuracy: ±10mm
 3. Medium density: ≥0.5g/cm3
 4. Working pressure: ≤2.5MPa
 5. Operating temperature: 0-200°C
 6. Medium viscosity: ≤0.4Pa·S
 7. Our factory's factory flange dimensions: DN150 PN1.6
 8. The flange uses the flange standard HG20592-20635-97 issued by the Ministry of Chemical Industry in 1998. If using other flange standards, please specify this when ordering. Flange connection hole layout shape: square.

5. Blind spots
 of top-mounted magnetic flip plate level gauges

Because there are certain structural blind spot values during measurement, compensation is required during reading. Depending on the density of the medium, the length of the float will vary, so the blind spot values will also vary.

6. Application Guidelines

1. Nominal pressure for anti-corrosion type≤ 1.0MPa
 . 2. The level gauge has a certain zone, so blind spot compensation should be added when reading the liquid level height (at the time of leaving the factory, the zero position on the scale has shifted to the actual value).
 3. The measurement range of the level gauge should not exceed 5 meters; otherwise, it will affect the stability and reliability of the gauge, as well as its durability.
 4. Install the connection flange; commonly used protruding surface dimensions for this level gauge are manufactured with reference (HG21592-97).

7. Installation, use, and maintenance

1. The level gauge guide tube and main tube must be installed vertically to ensure the float ball assembly can move freely up and down inside the main tube.
 2. The connecting rod must not bend and must be inserted vertically.
 3. After installation, use a magnet to guide the flipping column of the display once so that above zero it shows white and below zero shows red.
 4. After installing the liquid level gauge, use a magnet to calibrate it and guide the flipping column once so that below zero it shows red. Above zero, white is displayed.
