Insertion Electromagnetic flow meter

GMF400 Insertion Electromagnetic Flow Meter | GAIMC

Product Overview

GMF400 Insertion electromagnetic flow meter is composed of insertion electromagnetic sensor and electromagnetic flow converter, used to measure the conductive liquid that electrical conductivity is greater than 5 us/cm³. It is used to measure water, sewage, acid, alkali and other media. Suitable for measuring large pipes with diameter DN300~DN3000mm.

Installation can be divided into online installation type with cut-off valve and water control installation type without stop valves. The simple structure with no moving parts ensures long service life. It doesn't need lining or ground ring, featuring small volume, light weight, and convenient installation.

Insertion electromagnetic flow meter with stop valves can realize installation, disassembly, and easy maintenance when continuous streams are flowing. Flow measurement is only related to insert depth, so it has the feature of wide commonality and strong interchangeability. One model can be applicable to all kinds of pipe flow measurement requirements.
