Technical content

EGC100W is the high-performance separate type con- verter for electromagnetic fl owmeters with the compact housing. Improved self-diagnostic functions include empty pipe detection and conductivity monitoring. The easy-to-use converter in the fi eld, EGC100W is used in combi- nation with the MAGMAX series primary head.

FEATURES

❏ Standardized high-performance functions such as pulse output, bi-directional measurement, double ranges and status outputs including fl ow rate alarms. ❏ High accuracy of ±0.5% of reading. ❏ High speed data processing for quick response. Suitable for batch process control and pulsating fl ow. ❏ The extendable excitation system allows applications to much fl uid noise such as slurry. ❏ The LCD with backlight provides 1 to 3 lines of versatile indica- tion. ❏ Equipped with a quick setup function to readily respond to changed fl ow range, pulse rate, etc. The push buttons allow you to alter the settings without remov- ing the cover of conversion section. ❏ 10kHz high-speed pulse output. Capable of responding to short batch processes. STANDARD SPECIFICATION General Specifi cation
