Capacitance level meters

MHL series
MHL series
Capacitance level meter contributes to automation, saves energy, and saves manpower in various kinds of production

Ideal for measures liquids, corrosive liquids, powders, and granules continuously. Capacitance level meters that can be used in harsh environments.
*A 24VDC power supply in integrated has obtained CE marking.

  • For liquid
  • For powder

Many amplifiers and electrodes are available to match various conditions including integral and separate amplifier types.


Features, keys

  1. High precision
    Thanks to the latest circuit, the unit offers high precision and high resolution and can measure a miniature change of the level.
    A circuit is employed to correct liquid adhesion to the electrode.
  2. Can operate in harsh environments
    This meter can measure stably in harsh environments with high temperatures and pressures.
    The sanitary specification model has a fluorine resin coating on the electrode and so it holds up to heavy washing and is corrosion-proof.
  3. Simple to adjust
    It is easy to make the initial adjustments and span adjustment, using pushbuttons.
    You can adjust response speed using the delay setting function.
  4. Free-range power supply system is employed
    The switches can be used in any location in the world and can handle power from 20 to 250 volts, AC or DC.
  5. Obtained CE marking
    A 24VDC power supply in integrated has obtained CE marking.
