EGM1050C
Compact Electromagnetic Flowmeter
GENERAL
The inexpensive and user-friendly MAGMAX® EGM1050C is thecompact type electromagnetic ﬂowmeter with a converter EGC050
mounted integrally on a primary head EGS1000 lined with PFA.
The flowmeter is equipped with empty flow detection and statusmonitoring functions of primary head using the enhanced selfdiagnosis unit.
Lined with high-quality PFA and equipped with Hastelloy C® forelectrodes, the MAGMAX ® EGM1050C has 8 sizes from 10mm to 150 mm. In addition to water services such as city waterand waste water treatment, it is widely used for various chemicalprocesses.

FEATURE❑ The high-quality and clear PFA reinforced by the punched plates
assures the anti-corrosion, anti-erosion and anti-permeation.
❑ High accuracy of ±0.5% of reading.
❑ High speed data processing for quick response. Suitable forbatch process and pulsating ﬂow.
❑ The extendable excitation system allows applications to much
ﬂuid noise such as slurries.
❑ The LCD with backlight provides 1 to 3 lines of versatileindication.
❑ Equipped with a quick setup function to readily respond toSTANDARD SPECIFICATIONSGeneral Specifications
