1 MAGMAX EGM53C Compact Electromagnetic Flowmeter GENERAL MAGMAX EGM53C is a combination of EGS5 primary head with Ceramic measuring tube and high performance converter EGC3. EGM53C with high durability and high anti-corrosive capability is widely applicable for chemical liquid, slurry and many other applications. And improved self-diagnostic functions include vacancy detection and detection unit monitoring..5 to mm sizes are available. FEATURES Combination of Ceramic tube and Platinum electrodes is adopted for high anti-corrosive, anti-erosion, and anti-penetration capability. Dimensionally stable measuring tube with excellent temperature resistance and long-term stability, no creep and no abrasion as is the case with plastic liners. Stainless steel housing is adopt. The newly designed reducing tube offers high accuracy and stability even for low velocity range and mechanical durability of measuring tube. High accuracy of ±.5% of reading. High speed data processing for quick response. Suitable for batch process control and for 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 to 3-digit display. Equipped with a quick setup function to readily respond to changed 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. khz high-speed pulse output. Capable of responding to short batch processes. Current and pulse output, bi-directional measurement, double range, status output, control input...full function provided in compact design.
