How a magnetic level indicator works

The operational principle behind magnetic level indicator is used extensively regularly in levelling. Continuous level information is provided with just minimum upkeep required thanks to the collaborative efforts of the magnetic flags outside the chamber and the float magnets inside. Because it does not require any external power source, this level indicator may be utilised in various industrial settings.

The attraction and repulsion between two magnets that are very near to one another allow magnetic level indicators to function properly. The procedure is straightforward and efficient, providing real-time measurements of fluid levels.

Why is it necessary to use a magnetic level indicator in the first place?

For the magnetic level indicator to provide reliable readings, there can be no disparity between the volume of liquid in the measuring device and the volume of liquid in the vessel. The level indicator on the vessel is directly linked to the liquid that is being monitored. In the chamber, a float and magnet system has been fitted. There is something that floats about in the water. The float height adjusts as a direct result of the fluctuating level of the fluid. When the float moves up or down, the magnet assembly will spin a set of bicolour magnetic flags or flaps, which will cause a change in the colour of the exterior indicators.

The power for the magnetic level indication in these level-monitoring devices comes from the magnetic attraction and repulsion between metal objects. In addition to that, they require little in the way of upkeep.

In addition, the indicator’s magnetic force can activate transmitters and switches that are situated outside of the confinement region. The scale can offer accurate readings even from a great distance when combined with the bright flags. The appropriate dimensions and structure of the float utilised in the levelling process are heavily influenced by the medium and the temperature, pressure, and density of the process media.

Innovative Magnetic Level Gauges That Exceed All Expectations in Performance

An early version of the magnetic level indicator was one of Kuebler’s innovations for KSR-earlier Kuebler. A wide variety of high-quality magnetic level indicators maintain their ability to provide accurate readings over extended periods. Each MLI has a float tailored specifically to fit the needs of its intended use. When selecting the materials for the float magnet, careful consideration was taken to minimise the size of the float and the chamber while ensuring the greatest possible coupling for the pipe wall material and thickness requested.

Magnetic level indicators of the Model WMI kind are quite versatile in their application. They can operate in temperatures ranging from 195 to 537 degrees Fahrenheit (320 to 1,000 degrees Celsius), in vacuums reaching up to 5,000 psi (344 bar), and in environments with specific gravities as low as 0. You have the option of creating a wide number of different sorts of indicator flags, such as brilliant, red-white, or yellow-black flags.

You are free to present the information on the measurement units in any manner you like, including percentages, millimetres, centimetres, metres, feet and inches. In addition, the requirements of your operation may be addressed by choosing from a comprehensive inventory of drains, vents, and vent diameters.

Magnetic level indicators from WMI are widely utilised in a variety of commercial and industrial applications, including the following:

  • Technology may be employed in power plants and energy production developed in the chemical and refining sectors.
  • Offshore drilling and exploration necessitate the utilisation of oil and gas boilers, as well as feedwater heater pipeline compressors.
  • Our company operates a power plant, a paper mill, and a business that processes food.
