iMag 4700 Magnetic Flow Water Meter by Seametrics

iMAG 4700 Battery Powered Flanged In-line Magmeter FlowMeter SeametricsBattery Powered Flanged In-line Magmeter with one pulse output

The iMAG 4700 is the most economical flanged electromagnetic flowmeter on the market. With electrodes designed to discourage fouling, it is available in 3” to 12” pipe and is suitable for use in municipal or industrial water, waste and reclaimed water, pump stations, and packaged plant applications.

Minimal straight pipe requirements allow the iMAG-Series of magmeters to be used in piping configurations where there is little space between the meter and an elbow. The Seametric iMAG-Series meters are CE certified, certified to NSF/ANSI standard 61 and are rated IP68 for applications where the meter may be operated under water 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 key pad 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. 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 model. 


Applications: Water & Wastewater Treatment, Municipal, Pump skids, Pump stations, Packaged plants, Filtration systems, Reclaimed water, Hydraulic fracturing.
