1 EGMC Compact Electromagnetic Flowmeter GENERA MAGMAX EGMC is the compact type electromagnetic flowmeter with a converter EGC mounted integrally on a primary head EGS lined with fluorocarbon resin PFA. MAGMAX EGMC enjoys low cost and high performance thanks to the advanced converter, and the light weight and compact primary head. The flowmeter is equipped with empty flow detection and status monitoring functions of primary head using the enhanced self-diagnosis unit. ined with high-quality PFA and equipped with Hastelloy C for electrodes, MAGMAX EGMC has 8 sizes from mm to 5 mm. In addition to water services such as city water and waste water treatment, it is widely used for various chemical processes and utilities. FEATURES The high-quality and clear PFA reinforced by the punched plates assures the anti-corrosion, anti-erosion and anti-permeation. High accuracy of ±.5% of reading. High speed data processing for quick response. Suitable for batch process control and pulsating flow. The extendable excitation system allows applications to much fluid noise such as slurry. The CD with backlight provides to 3 lines of versatile indication. Equipped with a quick setup function to readily respond to changed flow range, pulse rate, etc. The push buttons allow you to alter the settings without removing the cover of conversion section. khz high-speed pulse output. Capable of responding to short batch processes. ized high-performance functions such as bi-directional measurement, double ranges and status outputs including flow rate alarms.
