Nexisense Magnetic Flip Plate Level Gauge

One Magnetic Flip Plate Level Gauge Solves the Problem of Intuitive and Reliable Liquid Level Indication under Complex Working Conditions

Traditional glass plate (tube) level gauges are prone to breakage and leakage, and have poor safety in high-temperature, high-pressure, and corrosive medium environments; although electronic level gauges have higher accuracy, they often experience signal drift or failure in strong interference or harsh field conditions. Nexisense Magnetic Flip Plate Level Gauge adopts the mechanical magnetic coupling principle, completely isolating the measured medium from the indicating part, avoiding leakage risks, and achieving the perfect combination of on-site intuitive indication and remote signal output. It is particularly suitable for industrial scenarios that require high reliability and visual monitoring.

Three Core Selling Points:

• Intuitive and Reliable On-site Indication: Red and white flip columns flip to display, red below the liquid level and white above the liquid level, with clear boundaries. Even in long-distance or low-light environments, it can be quickly read. It can work without power supply.

• Wide Working Condition Adaptability and High Stability: Supports wide temperature range of -40℃~450℃, high pressure ≤25.0MPa, corrosive media. Multiple models (side-mounted, anti-corrosion, heat-tracing, high-temperature and high-pressure, explosion-proof, etc.) are optional. Simple structure, reliable sealing, strong anti-vibration and anti-interference capabilities.

• Flexible Output and Easy Integration Capability: Optional 4-20mA/HART/RS485 output, supports remote transmission and automation system integration. Combined with on-site indication, it realizes dual monitoring of local and remote, meeting the needs of smart factories.

Overview

Nexisense Magnetic Flip Plate Level Gauge (also known as Magnetic Flip Column Level Gauge) is a liquid level measuring instrument based on the communicating vessel principle and magnetic coupling principle. When the liquid level in the measured container rises and falls, the magnetic float in the main tube of the level gauge rises and falls accordingly. The permanent magnetic steel inside the float transmits the signal to the external magnetic flip column indicator through magnetic coupling, driving the red and white flip columns to flip 180°, realizing real-time intuitive indication of the liquid level height. The instrument has the characteristics of simple structure, clear observation, no blockage, no leakage, convenient installation and maintenance, flexible use, stable performance and high reliability.

Based on the traditional magnetic flip plate structure, Nexisense optimizes the float magnetic system, flip column material and sealing design, and strengthens the transmitter output module, supporting multiple output methods such as 4-20mA, HART, and RS485 Modbus. System integrators can directly connect the level gauge to DCS, PLC or SCADA systems to realize real-time collection, trend analysis, over-limit alarm and remote monitoring of liquid level data; engineering contractors can quickly deploy in petroleum and petrochemical, power, environmental protection, pharmaceutical and other industry projects to ensure the visualization, controllability and high reliability of the liquid level process.

This series of level gauges has the characteristics of intuitive on-site indication, complete isolation of medium and indicating part, high temperature and high pressure resistance, corrosion resistance, stable electronic output, etc. It is the preferred equipment for liquid level measurement of complex media in industrial sites, especially suitable for occasions with extremely high requirements for safety and reliability.

Key Advantages

Nexisense Magnetic Flip Plate Level Gauge has undergone systematic optimization in structural design, material selection, magnetic coupling system and signal output, with emphasis on stability, high precision, anti-interference ability and easy integration to meet the needs of long-term stable operation of B2B projects.

1. Magnetic Coupling Principle and High Reliability
   Adopting buoyancy drive + magnetic coupling technology, there is no mechanical connection between the float and the flip column, completely isolating the measured medium from the external indicating part and avoiding leakage risks. The flip column turns clearly and reliably. Even in vibration or slight interference environments, it can maintain stable indication, with display accuracy of ±10mm, suitable for working conditions that require on-site intuitive reading.

2. Wide Medium Adaptability and Harsh Working Condition Design
   Medium pressure can reach 25.0MPa and below, temperature range -40℃~450℃, medium density ≥0.5g/cm³, viscosity ≤0.05Pa·S. Provides side-mounted type, top-mounted type, anti-corrosion type, heat-tracing type, high-temperature type, high-pressure type, high-temperature and high-pressure type, explosion-proof type and other models. Wetted materials can be selected from stainless steel, PVC, Ti, etc., to meet the needs of water, oil, chemical liquids, medicinal liquids, organic solvents and other media.

3. Industrial-grade Protection and Anti-interference Performance
   Overall sealing performance is excellent. Explosion-proof types support flameproof ExdIICT6 and intrinsically safe ExiaIICT6. The electronic output module adopts waterproof and explosion-proof design, with strong anti-electromagnetic interference ability and high reliability of electronic components. Even in strong magnetic fields or harsh industrial sites, the mechanical indicating part still maintains stable operation, and the electronic output signal is not affected by on-site interference.

4. Multiple Output Methods and System Integration
   Supports 4-20mA analog output, HART protocol, RS485 Modbus RTU and other outputs, with load resistance of 500Ω and power supply DC24V. Data includes liquid level height and status information, convenient for multi-slave networking and flexible baud rate configuration. The wiring module can be customized according to on-site needs, supporting the combination of on-site display and remote monitoring, and easily integrated into industrial automation and IoT platforms.

These advantages make Nexisense Magnetic Flip Plate Level Gauge not only an intuitive and reliable liquid level indicating instrument, but also a stable node that can be deeply integrated into the liquid level monitoring system of smart factories, helping users reduce leakage risks, improve process visualization and ensure production safety.

Wiring and Installation

This level gauge is easy to install, and the mechanical indicating part does not require power supply. Installation precautions are as follows:

• The direction of the connecting flange bolt holes on the user's equipment should be consistent with the direction of the flange screw holes on the level gauge.

• 2M identification沉筒距, the smaller the medium specific gravity, the longer the float, and the larger the沉筒距, and vice versa.

• There should be no magnetic conductors near the level gauge, otherwise it will directly affect the normal operation of the level gauge.

• When the level gauge is installed and put into operation, the liquid should enter the main pipe smoothly to avoid the float rising violently with the liquid, causing the magnetic flip column to flip incorrectly or the indication to be inaccurate (at this time, a magnetic steel can be used for correction, so that all below the liquid level shows red, and all above the liquid level shows white).

• The installation position of the magnetic flip plate level gauge should avoid or stay away from the medium inlet and outlet to avoid the rapid change of the local area of the fluid, which affects the accuracy of liquid level measurement.

Transmitter output module wiring: Power supply DC24V. When outputting 4-20mA/HART/RS485 signals, pay attention to the use of load resistance and shielded cables, and correctly configure the address and baud rate. Check the wiring before powering on. It is recommended to use an isolated power supply to reduce interference. For detailed installation dimensions and requirements, please refer to the product manual. After installation, it is recommended to perform zero point and full scale calibration.
