Flow Meter water iMAG 4700 Premium

The iMAG-Series  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.
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.
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.

iMAG Water Meter Accuracy
tabel akurasi elektromagnetik flow meter

These magnetic flow Meter can be installed horizontally, vertically (with 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 flow meter straight Pipe Recommendations.
The iMAG magnetic flow meter requires straight pipe before and after the meter for 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 sample period
