ADMAG CA magnetic flowmeter is excellent at measurement in ultra-low conductivity fluids down to 0.01 microS/cm, adhesive fluids, or slurry fluids. Since ADMAG CA employs a non-wetted electrode construction, picking up the signal voltage by electrode plates provided outside a ceramic pipe through the capacitance of the pipe.……



Features: ADMAG CA Series Capacitance Magnetic Flowmeters

Ultra-low conductivity fluid measurement

Capacitance type electrodes and very high impedance head amplifier of ADMAG CA make ultra-low conductive fluid measurement possible. High-frequency excitation reduces the effects of flow noise.

Adhesive fluid measurement

Non-wetted electrodes solve the measurement problem of sticking insulating material.

Slurry fluid measurement

Non-wetted electrodes are free from electric noise resulting from slurry colliding with the electrodes. Stable measurement in highly concentrated slurry fluids is possible.

High accuracy, +/- 0.5% of flow rate for ultra-low conductivity

For measurement of fluids with minimum conductivity of 0.1 microS/cm.


No adhesion, corrosion, or clogging greatly reduces maintenance costs. ADMAG CA is ideal for processes that used to need regular cleaning.

150 mm and 200 mm sizes

ADMAG CA is the first* ceramic capacitance type magnetic flowmeter in the world that supports 150 mm and 200 mm sizes, for even greater flexibility in applications.
