Insertion Type Electromagnetic Flow Meter | RWEM/C

Insertion Type Electromagnetic Flow Meter -Overview

The insertion type electromagnetic flow meter provides an economical option for large pipeline flow measurement while retaining the advantages of the common magnetic flow meter. It can be used for pipe sizes between DN100mm and DN3000mm. It can be easily installed due to its hot-tap structure. The main advantage of using an electromagnetic flow meter is that it has no moving parts. It requires very little maintenance.  This insertion type electromagnetic flow meter consists of an ABS or Polypropylene electromagnetic sensing probe mounted on the end of a support rod.
