Tokyo Keiso MAGMAX® EGM7300C Compact Electromagnetic Flowmeter
Made in Japan
Manufacturer: Tokyo Keiso
Model: EGM7300C
MAGMAX EGM7300C adopts flat capacitance detection type electrodes which are located outside of measuring tube made of ceramics instead of the conventional liquid contacting metallic electrodes for detection of flow velocity. Thanks to the capacitance detection and non-wetted electrode design, EGM7300C has achieved the stable measurement of very low conductivity liquids, highly concentrated slurries and adhesive liquids. With the self-diagnosis function EGM7300C has intensified its reliability by monitoring status of primary head.
Features
- Low conductivity liquid measurement down to 0.05μ S/cm
- High anti-corrosive capability, high durability against erosion….
- Stable measurement even for highly concentrated slurry liquids
- Stable measurement of high adhesive liquids
- High anti-vibration capability
- High accuracy of ± 0.5% of reading
- Blue dot matrix LCD with back light
- Quick and easy setting up when altering of flow rate range and pulse rate
- 10 kHz high-speed pulse output
- Compact design with high performance
