MAGMAX®

EGS5000
Electromagnetic Flowmeterwith Ceramic Tube
GENERALMAGMAX® EGS5000 is a separate type primary head of electromagnetic flowmeters with Ceramic measuring tube.
The erosion and corrosion resistant, and highly durable EGS5000 is
widely applicable for chemical liquid, slurry and many other applications. From the smallest 2.5 mm to 100 mm, 10 sizes are available.
EGS5000 is used in combination with MAGMAX® series converterof electromagnetic flowmeter.

FEATURES❏ Combination of Ceramic tube and Platinum electrodes is adopted for high anti-corrosive, anti-erosion, and anti-penetration
capability.
❏ The dimensionally stable measuring tube made of ceramic offers
a life-long higher accuracy than plastic liners.
❏ Stainless steel housing is adopted.

STANDARD SPECIFICATION❏ By reducing the affect caused by upstream velocity profile disturbances, the newly designed reducing tube offers an increased
