Seametrics iMAG 4700 Series Electromagnetic Flow Meter

Seametrics iMAG 4700 Series Electromagnetic Flow Meter | Features & Applications

The iMAG-Series is the most economical flanged electromagnetic flowmeter on the market. With electrodes designed to discourage fouling, it is available in 3” to 12” pipe in municipal or industrial water, waste and reclaimed water, pump stations, and packaged plant applications. Minimal straight pipe requirements allow iMAG-Series meters to be used in piping configurations where there is little space between the meter and an elbow.
