The magnetic float level gauge uses the principle of a linker to introduce the liquid level in the container into the body of the level gauge. The floating float assembly within the body is based on the principle of buoyancy and the principle of magnetic coupling. A display of the position of the liquid level of the column that reflects the magnetic phenomenon is attached to the outside of the body. As the liquid level in the main body changes, the height of the float assembly also changes accordingly. Therefore, the flip column outside the main body is turned 180 degrees. When the liquid level rises, the flip column changes from white to red. When the liquid level drops, the flip column turns from red to white. The red and white boundaries of the display are the actual heights of the media level in the container.
The magnetic float level gauge is a measuring component of the floating ball assembly. The floating ball moves up and down by the buoyancy of the liquid, and the magnetic steel at the upper end of the ejector is changed up and down, and the magnetic flip of the display assembly is turned over by magnetic coupling. Track liquid level changes, so the display is eye-catching, the reading is intuitive, because the display components are completely isolated from the measured medium, so the use is safe and reliable. The liquid level gauge is suitable for containers such as various underground tanks, and the liquid level display of containers which are not suitable for side opening. For example, the matching meter can be used for remote detection to realize automatic control function.
How can the magnetic float level gauge be installed to achieve good measurement results? Selection techniques, what should we consider?
The correct use of the magnetic float level gauge:
1. Check whether the liquid level meter is within the verification period before use. Otherwise, it should be checked and replaced if it is unqualified.
2, the sensor should be installed horizontally, the length of the entry should meet the technical requirements.
3. The connection between the sensor and the explosion-proof junction box should be tight and tight, and no rainwater should be leaked.
4, the wiring should be carried out according to the instructions for use, can not be shorted or wrong.
5. The float level gauge should work within the set observation range and must not work over the range.
Magnetic float level gauge correct maintenance method:
1. After 6 months to 1 year of operation, the sensor should be visually inspected and routinely verified.
2. Regularly check whether the sensor is bent and deformed by external force to avoid causing the card to malfunction.
3. Regularly check whether the sensor's magnetic sensor switch component is out of aging, not less than 1 time per month.
4. The sensor verification period is 1 year.
5, check the float ball level gauge protection casing must not have leakage phenomenon.
Magnetic float level gauges are used for liquid level detection of liquid media in various pressurized (or open) liquid storage equipment (towers, tanks, tanks, spherical vessels and boilers) in industrial processes. It can display the working condition and liquid level of various liquids on the spot. With the liquid level transmitter, the position signal of the liquid surface can be transmitted from a long distance. The purpose of automatic control and measurement of the liquid level is achieved by certain electrical devices.
The magnetic float level gauge has a direct reading feature for local display. There is no need for multiple sets of level gauges. With a single unit for full scale measurement. The device has fewer holes, the display is clear, and the mark is conspicuous. The readings are intuitive and so on. When the liquid level meter is directly equipped with a display device, the intermediate transmission of the signal detection of the system can be omitted to improve the transmission accuracy.
