ADMAG CA Series Capacitance Magnetic Flowmeters
1. Product introduction
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.
2. 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.
