1

1 :  Introduction

This manual describes how to install and operate the MagneW

TM

3000 FLEX/

PLUS NNK open channel electromagnetic flowmeter detector. If you are using a 

MagneW

TM

3000 FLEX/PLUS NNK in combination with a converter, refer to the 

operation manual of the converter.

Before installing a detector, make sure that its size is adequate by referring to the 

“Diameter Selection Graph” in the appendix of this manual.
