ADMAS electromagnetic flowmeter
Cantilever beam sensor
Product details


ADMAG CA electromagnetic flowmeter can measure low conductivity fluids with conductivity up to 0.01 µ s/cm, and is also suitable for measuring viscous fluids or slurries. Due to the non liquid electrode structure adopted by ADMAG CA, the electrode plate outside the ceramic tube can obtain electromotive force through the capacitance of the pipeline.


  • Measurable ultra-low conductivity fluid

    ADMAG CA uses capacitive electrodes and high impedance preamplifiers to measure low conductivity fluids. High frequency excitation reduces the impact of fluid noise.


  • Measurement of viscous fluids
    Non liquid electrodes solve the measurement problem of viscous insulating media.
  • Slurry measurement
    Non liquid electrodes do not have the problem of noise caused by slurry collision with electrodes. Stable measurement of high concentration slurry can be achieved.
  • High precision with a flow rate of ± 0.5%, used for ultra-low conductivity
    The conductivity of the measured fluid can be as low as 0.1 µ s/cm.
  • maintenance-free
    There are no issues of scaling, corrosion, or blockage, thereby significantly reducing maintenance costs. ADMAG CA is particularly suitable for processes that require regular cleaning.
  • 150mm and 200mm pipe diameters
    ADMAG CA provides ceramic capacitive electromagnetic flow meters with diameters of 150mm and 200mm, making their applications more flexible.
