  • The E4 Modulevel® model is a modernized version of the E3 Modulevel® displacer from Magnetrol.

    The operating principle of the displacer level transmitter is based on the buoyancy phenomenon of a selected rod called a displacer, immersed in the measured liquid. The buoyancy force depends on the level and is converted into an electrical output signal corresponding to the measurement range. E4 Modulevel® transmitters use a linear displacement sensor LVDT, which moves with the change of level, causing a change in magnetic induction. This is then recorded and converted into an output signal. The advantages of this solution comparing to the solution based on the torque tube are described in this article.

    A major advantage of liquid level measurement using the buoyancy method is the accurate measurement of the level or interface level in applications where foam, very high pressure and temperature or turbulence of the medium occur.

    E4 Modulevel® transmitters comply with the IEC 61508 standard and can be used in SIS automation systems with a SIL 2 / SIL 3 protection level.

    1. Alternative for displacer with torque tube

      Alternative for displacer with torque tube

      Displacers with torque tube are common level measurement devices in industrial applications. Their complicated mechanical design causes a lot of problems in use. Magnetrol's E3 Modulevel® displacer transmitters have no torque tube but LVDT (Linear Variable Differential Transformer) which makes these units easy to use and eliminates old generation transmitters' disadvantages.
