Magnetic level indicator


Customer was facing a problem of space constraint, hence there was no scope of dual chamber application which measures and control the condensate liquid level. It was important for the end user to measure and control the condensate liquid level at their plant in order to attain a quality and consistency in their production process.

Process Principle

Some oils are light, can be used almost immediately and are therefore very valuable. Other oils are heavy and must undergo additional refining processes before they can be used. One of the lightest and most valuable crude oils is condensate which is used to produce products like petrol, jet fuel, diesel and heating fuel. Depending on the temperature, condensate can take on various aggregate states - from liquid to gas.


SHRIDHAN, by using the above-mentioned process principle, provided the customer with a customized design in combination of MAGNETIC LEVEL INDICATOR WITH GWR Level Transmitter. It is a redundant design that suited the restricted space of the end-user

Technology Overview and Advantages

The magnetic level indicator working principle is widely used in level instrumentation. The interaction between float magnets inside the chamber and magnetic flags outside the chamber provide virtually maintenance-free, continuous level information. This type of level indicator doesn’t require power, making it ideal for a variety of applications across industries.

Magnetic level indicators are commonly low-cost in comparison with other level technologies and can provide visual indication of level from a distance. MLI devices are popular in applications measuring high-temperature, high-pressure, and corrosive liquids. When the application is challenging, magnetic level transmitters provide consistent, accurate measurements

Key advantage of guided wave radar level measurement is that no compensation is necessary for changes in density, dielectric or conductivity of the fluid. Further, changes in pressure, temperature and most vapour phase conditions have no impact on measurement accuracy; GWR is unaffected by high turbulence or vibrations; and build-up has practically no effect, meaning no need for re-calibration.

The advantage of having Magnetic level indicator with GWR level transmitter is

  • Redundant Level Technology
  • Increased Plant and Personnel Safety
  • Single Process Connection for Two Independent Devices


The GWR transmitter obtains an independent reading of the liquid level, providing an accurate output even in the case of a float failure. Also, the GWR level transmitter will read the true level of the fluid, even if the density of the product varies.


Shridhan team were successful in installing Magnetic level Indicator with GWR that helped end-user to measure and control Condensate level of liquid, to meet their quality standards. The result is true level-measurement redundancy in a single-chamber design. Shridhan always strived for meeting organisational goals with meeting their customer requirements, and have gained an competitive edge over the product by manufacturing a unique design to fit in the space and the needs of the end-user.
