iMAG 4700P Electrical Flow Meter

The iMAG-Series Electrical Flow Meter is the most economical flanged electromagnetic flowmeter on the market. With electrodes designed to discourage fouling, it is available in 2” to 12” pipes in municipal or industrial water/ wastewater and reclaimed water applications. Pump station, pump skid, and packaged plant applications are also suitable. 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.
