Preface
Thank you for purchasing our smart
two-wire electromagnetic flowmeter
.
The MagneW Neo / MagneW T
wo-wire PLUS is a landmark electromagnetic
flowmeter that is operated on 4-20 mA DC.
Based on our extensive experience in the
field, meticulous care is taken in the de
tector lining material
and waterproofing
properties to secure
high reliability
.
