MAGMAX®

EGC300F/EGC300W
Converter for Electromagnetic Flowmeter
GENERALMAGMAX® EGC300F/EGC300W series is a separate type converter for electromagnetic flowmeters, which has various functions,high accuracy and high reliability.
An excitation system extendable up to twice the commercial frequency has been introduced to reduce fluid noise.
And improved self-diagnostic functions include vacancy detection
and detection unit monitoring.
Two types of field installation type EGC300F and wall installation
type EGC300W are selectable.

FEATURES❏ Current and pulse output, bi-directional measurement, doublerange, status output, control input...Full function provided incompact design.
❏ High accuracy of ±0.5% of reading.
❏ High speed data processing for quick response. Suitable forbatch process control and pulsating flow.
❏ The excitation system extendable up to twice the commercial
frequency allows applications to much fluid noise such as slurry.
❏ Blue dot matrix LCD (with backlight) used for the display. Capable of providing 1 to 3-digit display.
❏ Equipped with a quick setup function to readily respond tochanged flow range, pulse rate, etc.
A touch panel system by an infrared sensor allows you to alter
the settings without removing the cover of the conversion section.
❏ 10 kHz high-speed pulse output. Capable of responding to shortbatch processes.
