YOKOGAWA ADMAG CA Series Capacitance Magnetic Flowmeters
2015-06-29 15:48:25
Description:
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.……

Description
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. | |
| 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. | |
| *: As of September 29, 1999. | |
