Level Meter Overview

Level meter performance at a glance

The float outside the measuring rod moves up and down along the measuring rod with the change of liquid level. When the permanent magnet ring inside the float meets the pulse current magnetic field in the probe rod, the magnetic field changes, and a torsional wave pulse is generated at the position where the float is located. This pulse is transmitted back along the waveguide wire at a fixed speed.
   By measuring the time difference between the pulse current and the torsional wave, the position of the float can be accurately determined, that is, the position of the liquid surface.
   The highest accuracy can reach 0.1mm.

Nexisense magnetostrictive level meter is developed based on the magnetostrictive effect (Wiedemann effect) and belongs to high-precision volumetric/non-contact level measuring instruments. The instrument adopts the waveguide pulse working principle. The float moves up and down with the change of liquid level. The permanent magnet ring inside interacts with the pulse magnetic field of the waveguide wire to generate a torsional wave. High-resolution level detection is achieved by accurately measuring the time difference. This technology eliminates the common mechanical wear, drift and medium interference problems of traditional level meters and provides a long-term stable, maintenance-free measurement solution.

On the basis of the classic magnetostrictive structure, Nexisense has optimized the electronic processing unit and output interface, strengthening industrial-grade anti-interference capability and system integration characteristics. System integrators can connect the level meter to the automation control system through standard 4-20mA or RS485/Modbus protocol to realize real-time collection, trend analysis, level alarm and remote monitoring of level data. Engineering contractors can quickly deploy it in projects in industries such as petrochemical, tank management, fine chemical, food and pharmaceutical, ensuring controllability, traceability and high reliability of the level process.

This series of level meters has the characteristics of high precision, no moving parts (except the float), low maintenance, resistance to high temperature and high pressure, resistance to corrosive media, and high reliability of electronic components. It is the preferred equipment for precision measurement of complex liquids in industrial field.

The float adopts stainless steel or PTFE anti-corrosion material, which is not easy to demagnetize after long-term use and adapts to high temperature, high pressure and strong corrosive environments.

3. Industrial-grade protection and low maintenance design
          No other moving parts except the magnetic float, and the later maintenance amount is extremely small. The electronic unit adopts waterproof and explosion-proof wiring module design, with strong anti-electromagnetic interference capability and high reliability of electronic components. The overall structure is compact and suitable for long-term operation in harsh industrial sites.

4. Multiple output methods and deep integration
          Supports 4-20mA analog output (default), RS485 Modbus RTU, HART protocol or combined output. Data includes real-time level, status information, etc., which is convenient for multi-slave networking and flexible baud rate configuration. It is easy to integrate into industrial automation systems or IoT platforms. The wiring module can be customized according to site requirements and supports on-site display function.

These advantages make the Nexisense magnetostrictive level meter not only a level measuring instrument, but also a reliable node that can be deeply integrated into the smart factory level monitoring and control system, helping users improve process control accuracy, reduce maintenance costs and ensure production safety.
