YOKOGAWA ADMAG CA Series Magnetic Flowmeters
The YOKOGAWA ADMAG CA magnetic flowmeter adopts a system to pick up the electromotive force generated in a fluid by electrodes provided outside a ceramic pipe through the capacitance of the pipe. In addition, the flowmeter employs a prominent high-frequency excitation method that reduces flow noise in low conductivity fluid.

Features
- 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.
- Maintenance-free
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.
