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.
Very small flow rate can be covered:  Min. 0 - 0.5 L/h [Water] can be measured.  
 Alarm output option available:    In addition to local indication type, alarm output version is also available.
 Compact design:   Easy installation onto instrument panel.
 Safety for high temperature and pressure: All metallic material construction covers tough applications!
