Tokyo Keiso MAGMAX® EGC300W Electromagnetic Flowmeter Converter
Made in Japan
Manufacturer: Tokyo Keiso
Model: EGC300W
MAGMAX® EGC300W is a field installation type converter which is used in combination with MAGMAX® series electromagnetic flowmeter primary head.
The fluid noise during measurement has been reduced by the excitation method. The method enables to raise the frequency to twice as high as the commercial power frequency. Improved self-diagnosis functions such as empty detection, monitoring of detector, etc. are provided.
Features
- Various high functions equipped: Pulse output, bidirectional flow measurement, double range, output of status such as flow alarm and control input provided as standard.
- High accuracy of ±0.5% of reading
- High speed data processing for quick response. Suitable for batch control process and pulsating flow.
- Field current frequency can be adjusted up to twice of main frequency which is effective for slurry noise rejection.
- Easily visible and blue dot matrix LCD indicator offers flexible indication.
- Quick set-up function for easy data setting/change such as scale range, pulse rate, etc.
- All setting parameters can be set/changed by an infrared touch sensor without opening the housing cover.
- High pulse rate up to 10 kHz offers high resolution for short time batch process control.
- HART® communication provided as standard.
