The composition of the magnetic flap level gauge and the solution of the false liquid level
Shelf lighting is a lighting solution specifically designed for commercial and retail environments. Its goal is to highlight and display the goods on the shelves by providing appropriate lighting to attract customer's attention and increase sales.

Shanghai Automation Instrument Co., Ltd. magnetic flap level gauge consists of body, flap box (composed of red and white two-color magnetic small flap), float, flange cover, etc., used for liquid level measurement of various liquid containers. The magnetic flap level gauge can be used for high-temperature, explosion-proof, anti-corrosion, food and beverage, etc., for local display or remote display and control of liquid level. UHZ series magnetic flap level gauge can achieve high sealing, anti-leakage and safe and reliable measurement of liquid level under high temperature, high pressure, high viscosity and strong corrosive conditions. The whole process measurement has no blind zone, the display is eye-catching, the reading is intuitive, and The measuring range is large, equipped with liquid level alarm and control switch, which can realize the upper and lower limit alarm and control of liquid level or boundary, and the liquid level transmitter can be used to set the liquid level. The boundary signal is converted into a standard signal of two-wire 4~20mADC to realize remote detection, indication, recording and control. UHZ series magnetic flap level gauges are widely used in liquid level measurement and control in the production process of electric power, petroleum, chemical, metallurgy, environmental protection, shipbuilding, construction, food and other industries.
Like any other meter, the magnetic flap is used for a long time, and it will always be a little bit ill, such as a false liquid level.
The magnetic flap level gauge is prone to false liquid level in long-term use, which brings an illusion to the user. What is the reason for the false liquid level of the magnetic flap level gauge? Let us discuss this:
1, first determine the liquid phase, the gas phase are all through!
2. Use a magnet to sweep the entire surface along the surface, you can understand that it will be corrected.
3. If it is a safe liquid, first discharge the liquid phase and perform the operation;
4. If the vapor pressure in the gas phase is large, turn off the gas phase cutting, press the liquid in the tube back to the storage tank, and perform 2, operation. The top-mounted magnetic flap level gauge is suitable for measuring various containers that are not convenient for side-mounted level gauges, especially for level measurement in underground tanks. Widely used in petroleum, chemical, metallurgy, electric power, light industry and pharmaceutical industries and sectors.
5. The external interference signal is too large, causing the circuit to obtain a false signal, not the actual measured signal;
6. The fault of the waveguide wire inside the liquid level gauge, such as looseness, poor sealing and water rust, etc., causing signal distortion;
7. The waveguide wire is not installed correctly and the signal transmission is distorted;
8. The signal processing circuit is faulty.
The magnetic flap level gauge produces a liquid level gauge that adapts to various environments and various materials according to different working environments, including: hydraulic machine level gauge, UHZ-F anti-corrosion type magnetic flap level gauge, and thermal insulation. Jacket flap level gauge, high temperature and high pressure magnetic flip column level, UHZ top mount magnetic float level gauge, HG5-1 glass plate level gauge, HG5-2 frost level gauge, HG5 glass tube level Meter, UNS (UGS) color quartz tube liquid level gauge, UHZ-59 series magnetic flip column (plate) level gauge and other types of products.

The classification and layout of shelf lighting can be selected according to different needs and scenarios. LED lamps are the most commonly used shelf lighting technology and are favored for their high efficiency, long life, and dimmable characteristics. Overhead lights and strip lights are common installation locations and can be selected according to the needs of the appropriate way to provide overall or local lighting.
In terms of lighting layout, uniform lighting, and directional lighting are common choices. Uniform lighting ensures consistent lighting intensity for merchandise by providing a balanced distribution of light across the entire shelf. Directional lighting uses lamps such as spotlights or downlights to focus light on specific goods or display areas to highlight their characteristics.
Lighting control is also an important consideration. The dimmable lighting system can adjust the lighting brightness as needed to adapt to different environments and product display needs. Smart lighting systems automatically adjust lighting intensity and color through factors such as sensors, timers, or external conditions, providing greater flexibility and energy efficiency.
Through the appropriate shelf lighting program, businesses can create a pleasant shopping environment, highlight product characteristics, attract customers' attention, and improve sales performance. Shelf lighting plays an important role in modern retail, providing businesses with a means to promote products effectively.
