Seametrics iMAG 4700 Series Electromagnetic Flow Meter
Seametrics iMAG 4700 Series Electromagnetic 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” 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.
The iMAG 4700 is also available in either AC or DC powered versions, with battery backup. Pulse output is standard on all models, while 4-20mA passive current loop is also standard on the iMAG 4700p. 4-20mA loop is optional on the iMAG 4700 and iMAG 4700r externally powered meters and Modbus® protocol outputs are optional on all models although battery life will be reduced if ordered on battery powered units. A power / output cable allows outputs for use with a variety of Seametrics displays and other controls for remote reading and telemetry applications.
