MAGMAX®

EGM5100C
Compact Electromagnetic Flowmeter
GENERALMAGMAX® EGM5100C is a combination of EGS5000 primaryhead with Ceramic measuring tube and converter EGC100.
EGM5100C with high durability and high anti-corrosive capability is
widely applicable for chemical liquid, slurry and many other applications.
Improved self-diagnostic functions include empty pipe detection
and conductivity monitoring.
2.5 to 100mm 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 adopted.
❏ The newly designed reducing tube offers high accuracy andstability even for low velocity range and mechanical durability ofmeasuring tube.
❏ High accuracy of ±0.5% of reading.
