iMAG 4700 Seametric Electromagnetic Water Flow Meter

Description

The iMAG 4700 flow meter 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 the iMAG-Series flow meter to be used in piping configurations where there is little space between the meter and an elbow.

iMAG 4700 magnetic-flowmeter are CE certified, certified to NSF/ANSI standard 61, and are rated IP68 for applications where the meter may be operated underwater to a depth of at least 10 feet (3 meters) continuously.

The display can be meter mounted or remote, and both rate and total indication are standard. Rate and total units and pulse scaling can be set via the front panel touch keypad by the user. Bidirectional flow reading is standard with totals available in forward, reverse, net flow, batch forward flow, and batch reverse flow. Batch totals can be reset.

A power/output cable allows outputs for use with a variety of Seametrics and other displays and controls for remote reading and telemetry applications. The pulse output is standard on all models and 4-20mA passive current loop is standard on the iMAG 4700p. In addition, 4-20mA loop, HART protocol, high-speed digital, and Modbus® protocol outputs are optional on the externally powered units, depending on the model.
