Magnetic flow
meter iMAG 4700is the most economical flanged electromagnetic flowmeter
on the market produced by seametric instrument. With electrodes
designed to discourage fouling, it is available in 4” to 12” pipe in
municipal or industrial water, waste and reclaimed water, pump stations,
and packaged plant applications. (For 3” version, see iMAG 4600-300.) Minimal straight pipe requirements allow.
Magnetic flowmeters iMAG to be used in piping configurations where there is little space between the meter and an elbow.

Water flow meter iMAG
4700 are NSF-61 approved 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 magnetic flow meter iMAG 4700 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 is standard with forward, reverse and net flow.
A power/output cable imag water flow meter allows outputs for use with a variety of Seametrics inc USA 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.

iMAG Water Meter Accuracy
These
magnetic flow Meters can be installed horizontally, vertically (with
the downward flow), or in any radial position. Using a check valve on
the upstream side of the meter, and/or an air vent (vacuum relief valve)
in the same, unobstructed run of pipe as the meter, is
required in any installation where the meter may be exposed to suction
when the system is not in normal operation. Suction can cause damage to
the liner. Liner damage caused by suction, without the use of a check
valve and/or air vent, may void the warranty.

iMAG water flows meter straight Pipe Recommendations.
The iMAG
magnetic flow meter requires a straight pipe before and after the meter
for the best accuracy. However, the ability of electromagnetic meters to
average the flow across the entire pipe allows for shorter straight
pipe recommendations than most mechanical meters

Pulse Output Configuration.
A
pulse output is standard on all models. Since this is an isolated
output, the external equipment must include a DC power source to
regenerate the pulse from the open-collector output (transistor
equivalent of a contact closure). A pull-up or pull-down resistor may be
needed if not included in the user equipment as shown in the diagrams.
Both the power source and resistor may be supplied internally in some types of control and monitoring magnetic flow meter devices. If not, as for most PLC discrete input modules, they must be added externally at the module input terminals. The pulse output rate in volume units/pulse can be set by the user via the SET P tab on the meter’s setup menus.

Battery Powered Units
The iMAG 4700 flow meter can come configured with two replaceable 3.6V lithium ‘D’ batteries. In this configuration, the only option/output is the scaled pulse output which comes standard. The scaled output for the battery-powered option has a maximum pulse rate of 150 pulses/second, with a fixed pulse width of 2.5ms. Be sure to set your P-value such that the meter will function properly over the flow range in your flow meter application.The sample rate of the meter is user selectable through the SAMP tab in the meter’s sub-menu. Sample periods of 1/5, 1/3, 1, 3, 5, 15, 30, and 60 seconds can be selected. Larger sample periods will yield longer battery life but slower response time. Care must be taken to select a sample period that is suitable for your application. See the table below for the expected battery life as a function of the sample period
