Flow Ceramic tube Electromagnetic flowmeter Primary headMAGMAX® EGS5000

Ceramic tube Electromagnetic flowmeter Primary head MAGMAX<sup>®</sup> EGS5000


*Specifications are subject to change without prior notice.

MAGMAX® EGS5000 is a wafer type primary head of electromagnetic flowmeter with a ceramic tube. From 2.5 mm to 100 mm, 10 sizes are lined up.
This meter is used in combination with MAGMAX® series converter of electromagnetic flowmeter.
EGS5000F excels in corrosion resistance, abrasion resistance, and durability. It is most suitable for highly accurate measurement of chemical liquids and slurries.
* MAGMAX® is registered trademark of the TOKYO KEISO CO.,LTD.


  • · As a combination of a ceramic tube and platinum electrodes is adopted, this meter excels in corrosion resistance, abrasion resistance, and durability.
  • · For the sizes from 2.5 to 15 mm, zirconia ceramic which is tolerant of thermal shock has been employed for the tube.
  • · Ceramic tube excels in dimensional stability compared to resin lining tube; this meter maintains high accuracy in a long term.
  • · Reducing tube has been employed: The influence of flow velocity distribution at the upstream has been decreased. Accuracy and stability have been improved. Measuring tube has become more rigid.
  • · Stainless steel housing is employed.
  • · High accuracy of ±0.5% of reading.
