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/cm , it is used to measure the water, sewage, acid, alkali and other medium. Suitable for measuring the large pipe of diameter DN300~DN3000mm,. Installation can be divided into a online installation type of the cut-off valve and water control installation type without stop valves.


Insertion flow meter devices measure the point velocity of the liquid in a pipe.  Flows in very large pipes can be measured this way using relatively inexpensive metering devices. Essentially an appropriately sized hole is drilled into the pipe wall and a means of securing the insertion meter is applied. This can be a saddle clamp, weld-on threaded stub or a mating flange.
