How to wire the magnetic flap level gauge

Magnetic flap level gauges can be used for medium level detection in various equipment such as towers, tanks, tanks, spherical vessels, and boilers. This series of liquid level gauges can achieve high sealing, leak prevention, and are suitable for high temperature, high pressure, and corrosion-resistant applications. It compensates for the defects of poor clarity and easy breakage of glass plate (tube) level gauges, and the entire measurement process has no blind spots, clear display, and a large measurement range. The component materials of the magnetic flap level gauge are 1Cr18Ni9Ti, 316L, OCr18Ni9Ti, and 1Cr18Ni9Ti lined with PTFE（Polytetrafluoroethylene）ThePVC、 PP and other materials, as well as imported components, have excellent reliability and corrosion resistance

Magnetic flap level gauges have been produced to adapt to various working environments and materials, including hydraulic press level gauges, anti-corrosion magnetic flap level gauges, insulation jacket flap level gauges, high-temperature and high-pressure magnetic flap column level gauges, top mounted magnetic float level gauges, glass plate level gauges, frost resistant level gauges, glass tube level gauges, colored quartz tube level gauges, series magnetic flap column (plate) level gauges, and more.

Magnetic flap level gauge (also known asMagnetic float level gauge）According to the principle of buoyancy and magnetismcouplingDeveloped through functional research and development. When the liquid level in the tested container rises or falls, the magnetic float in the liquid level gauge body tube also rises or falls accordingly. The permanent magnet in the float is transmitted to the magnetic flip column indicator through magnetic coupling, driving the red and white flip columns to flip 180 °. When the liquid level rises, the flip column changes from white to red, and when the liquid level drops, it changes from red to white. The red white boundary of the indicator is the actual height of the liquid level inside the container, thus achieving clear indication of the liquid level.

The magnetic flap level gauge can be directly used to observe the liquid level height of various media in containers. It is suitable for liquid level indication in industries such as petroleum and chemical. The liquid level gauge has a simple structure, intuitive and clear observation, no blockage or leakage, easy installation, and simple maintenance. The upper and lower ends of the glass plate level gauge are connected to the container by flanges, forming a connector. The actual height of the liquid level in the container can be directly observed through the glass plate. The upper and lower valves are equipped with safety steel balls. When the glass is accidentally damaged, the steel balls will automatically seal under the pressure inside the container, preventing liquid from overflowing and ensuring the safety of operators.

For those exceeding a certain length, it is necessary to add intermediate reinforcement flanges or ear hooks as fixed supports to increase strength and overcome their own weight; The installation position of the magnetic flap level gauge should avoid or be far away from the inlet and outlet of the material medium to avoid rapid changes in the local area of the material fluid, which may affect the accuracy of the level measurement; When equipped with remote transmission supporting instruments, the following requirements should be met: the zero position of the remote transmission supporting instrument should be on the same horizontal line as the zero position indication of the liquid level gauge; The connection between the remote transmission supporting instrument and the display instrument or industrial control computer should be laid separately through protective pipes or with shielded two core cables; The remote transmission supporting instruments should be tightly attached to the main pipe of the liquid level gauge and fixed with stainless steel clamps (iron is prohibited); The sensing surface on the remote transmission supporting instrument should face and be closely attached to the main pipe; After the wiring holes of the junction box are laid, it is required to be well sealed to prevent rainwater, moisture, and other factors from entering and causing the remote transmission supporting instruments to malfunction. The junction box should be promptly covered after maintenance or debugging is completed.

Magnetic conductors are not allowed to approach the main body, otherwise it will directly affect the accurate operation of the liquid level gauge. In order to prevent damage to the float component during transportation, the float component is removed from the main tube of the liquid level gauge before leaving the factory. After the installation of the liquid level gauge is completed, the bottom drain flange is opened, and the float component is reinstalled into the main tube. Note that the heavy end of the float component is facing upwards and cannot be inverted.

The measurement method and troubleshooting of magnetic flap level gauge

When measuring liquids, the top mounted or side mounted method is used. Install a flip column liquid level indicator, liquid level switch, and liquid level transmitter outside the magnetic flip column body. The magnetic unit is placed inside the floating ball or connected to the floating ball through a top rod. When the floating ball and the magnetic unit change with the liquid level, the magnetic color block (magnetic flip plate) is flipped; The magnetic liquid level switch operates at the corresponding liquid level point; At the same time, the liquid level sensor outputs a standard variable resistance signal under the action of the floating ball magnetic force, and then converts the resistance signal into a 4-20mA current signal output through the transmitter.

7 Precautions for Using Magnetic Flip Plate Level Gauge

For liquid level gauges that exceed a certain length (ordinary type>3 meters, anti-corrosion type>2 meters).

2. The installation position of the magnetic flap level gauge should avoid or be far away from the inlet and outlet of the material medium to avoid rapid changes in the local area of the material fluid, which may affect the accuracy of the level measurement;

When equipped with remote transmission instruments, the following measures should be taken:

4. The remote transmission supporting instruments should be tightly attached to the main pipe of the liquid level gauge and fixed with stainless steel clamps (iron is prohibited);

5. The sensing surface on the remote transmission supporting instrument should face and be closely attached to the main pipe;

6. When debugging, the upper inlet valve should be opened first, and then the lower valve should be slowly opened to allow the medium to enter the main pipe smoothly (during operation, the medium should avoid rapid impact on the float, causing the float to fluctuate dramatically and affecting the display accuracy). Observe whether the magnetic red and white balls flip normally, then close the lower inlet valve, open the drain valve, and let the liquid level in the main pipe decrease. Follow this method three times, if it is normal, it can be put into operation (except for corrosive and other special liquids);

7. According to the condition of the medium, the main tube of the magnetic flap level gauge should be cleaned irregularly to remove impurities；

The magnetic flap level gauge consists of a body, a flap box (composed of red and white dual color magnetic flaps), a float, a flange cover, etc., and is used for measuring the level of various liquid containers. Magnetic flap level gauges can be used for on-site or remote display and control of liquid levels in high-temperature, explosion-proof, anti-corrosion, food and beverage applications. The magnetic flap level gauge can achieve high sealing, leak prevention, and safe and reliable measurement of liquid level under high temperature, high pressure, high viscosity, and strong corrosive conditions. The entire measurement process has no blind spots, eye-catching display, intuitive reading, and a large measurement range. Equipped with liquid level alarm and control switch, it can achieve upper and lower limit alarm and control of liquid level or boundary. Equipped with a liquid level transmitter, it can adjust the liquid level. The boundary signal is converted into a standard signal of 4-20mADC in a two-wire system, enabling remote detection, indication, recording, and control. Magnetic flap level gauges are widely used for liquid level measurement and control in the production processes of industries such as power, petroleum, chemical, metallurgy, environmental protection, shipbuilding, construction, and food.
