ADMAG CA电磁流量计凭借陶瓷管外部设置的电极板，通过管道电容获取电动势。此外，流量计采用了一种的高频励磁方式，使低电导率流体的噪声明显降低。

ADMAG CA电磁流量计可测量电导率低至0.01µs/cm的低电导率流体，还适用于粘性流体或浆液测量。由于ADMAG CA采用非接液式电极结构，陶瓷管外部设置的电极板可通过管道的电容获取电动势。

■ Dual compartment housing separates the wiring
section from the electronics and protects the
electronics from corrosive environments.
■ High accuracy, ±0.5 % of flow rate (size 25 to 100
mm (1 to 4 in.))
■ STANDARD SPECIFICATIONS
Degrees of Protection :
IP67, Type 4X
Grounding:
• 100 Ω or less
•When optional code A (lightning protector) is
selected, Class C (10 Ω or less)
•In case of TIIS Flameproof type, Class A (10 Ω or
less) or Class C (10 Ω or less)
•In case of explosion proof type except TIIS, follow
the domestic electrical requirements as regulated
in each country.
■ Magnetic Flow Converter
* : For models with no indicator, a hand-held
terminal is necessary to set parameters.
** : Pulse output and alarm output use commom
terminals, therefore these functions are not
available at the same time.
