INSTALLATION
iMAG 4700 INSTRUCTIONS
Positioning the Meter
Installing Gaskets
CAUTION: These flow sensors are not recommended where installation may expose the flow sensor to boiler pressure and temperature. Maximum recommended operating temperature is 140° F (60° C).
GASKETS Gaskets are required at all junctions.
These meters can be installed horizontally, vertically (with upward 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.
Straight Pipe Recommendations. The iMAG 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 (see page 7).
Full Pipe Recommendations. To prevent false readings, this meter is designed to indicate `EMPTY PIPE’ if one or more electrodes is exposed. For highest accuracy, install the meter so that the pipe will be full when there is flow. If air bubbles may be present in the pipe or sludge accumulation is an issue, rotate the meter by one flange hole to position the control housing at a 45° angle (see diagrams on page 8).
Fittings. The iMAG has ANSI 150 lb. drilled flanges and will mate with any other ANSI 150 lb. flanges. See table on page 10 for flange bolt tightening torque specifications.
Calibration. The iMAG is factory-calibrated before shipping. The frequency of recalibration will depend on the needs of each application and local regulatory policies.
Chemical Injection. When the iMAG is used in a chemical injection application, the chemical injection point must be placed downstream of the magmeter OR far enough upstream for complete mixing to occur before the fluid reaches the meter. When unmixed chemical alternates with water passing through the meter, the rapid changes in conductivity may cause sudden spikes and drops in the meter’s reading, resulting in inaccurate measurement. The magmeter will re-stabilize, however, with a steady flow of fluid of uniform conductivity.
1. Be sure all mating surfaces are smooth and free of debris.
2. Install Seametrics provided gaskets, or equivalent, on each end of meter as shown in diagrams below. If using grounding rings, install one gasket on each side of the grounding ring.
3. Failure to install gaskets will void warranty.
Gaskets Installation without grounding rings
Grounding Rings
Gaskets Installation with grounding rings
CAUTION: In chemical injection applications, install chemical injection point downstream of magmeter, or far enough upstream to allow complete mixing of fluids.

IMAG 4700 INSTRUCTIONS
Tightening Flange Bolts
Equalization and Grounding
NOTE: Mating pipe flanges must be ANSI 150# full face (FF) and/or raised face (RF).
1. Tighten flange bolts in an alternating pattern. · Tighten left flange bolt-1 to 20% recommended torque.
· Tighten right flange bolt-1 to 20% of recommended torque.
· Repeat steps a and b for each bolt in an alternating order, such as shown at right, tightening to 40%, then 60%, then 80%, and then 100%.
2. Test for leaks.
3. If needed, tighten further in 10% increments until leaking stops. DO NOT over-tighten. Overtightening can cause serious damage to the flow meter.
4. Recheck after 24 hours, adjusting if needed.

WARNING: ELECTRICAL SHOCK HAZARD When the iMAG is installed in a plastic piping system, or when externally powered, the piping system must be grounded to meet national and local electrical safety codes. Failure to do so can result in electrocution.
Metal Pipe Installations. To equalize the electrical potential of the fluid, the iMAG meter, and the surrounding pipe, secure the flange plates (factory-installed on the equalization wire) to both pipe flanges at one of the bolt holes, as shown below. Be sure the lock washer fits between the pipe flange and the flange plate. For the best electrical bonding, remove rust and paint to expose clean, bare metal where the equalization flange plate lock washer contacts the pipe flange. Connection must be inspected periodically for corrosion to maintain the necessary low resistance connection.

Because the pulse output of an iMAG 4700 meter is set by the user, care must be taken to assure the output pulses do not exceed the maximum frequency of the meter while also ensuring a reasonable resolution.
Lower frequency output pulses (1 pulse for some particular number of gallons) can also be set.
Any output frequency can be determined by:
K-factor: Remember that SETP is expressed in units totaled per output pulse (G/P if using gallons) while K-factors are expressed in pulses per gallon (P/G.) To determine K-factor from SETP, divide 1 by SETP (if SETP is expressed in gallons.) Conversely, 1 divided by the K-factor equals SETP
iMAG 4700 meters that were initially configured as battery powered units have a maximum output frequency of 150 Hz. Those that were initially configured as powered units have a maximum output frequency of 200 Hz.
Because all pulse outputs (SETP) are configured in (rate) units totaled per pulse, all sizes of meters can be configured with the same SETP values. For example, if your rate is chosen as gallons per minute (GPM) the table below applies.
Pulse Units. The units of measure of SETP are independently selectable and are not tied to rate or total. Upon change of the SETP unit, the pulse output may take up to 10 seconds, or the duration of one pulse (whichever is longer) to take effect.
Rate (units/minute) ÷ SETP (units/pulse) = pulse/minute Hz = pulse/minute ÷ 60 seconds / minutes

CONFIGURATION
IMAG 4700 INSTRUCTIONS
Analog Output (4-20mA) Configuration. (Not available on battery only units.)
Since the meter’s analog output is isolated and passive, loop power must be supplied externally as shown previously. (In addition, an external resistor RL will be needed to convert the loop current to voltage for voltage-only input devices.)
The meter’s loop transmitter minimum voltage drop is 6Vdc which, with wiring resistance and loop power supply voltage, will determine the maximum resistance for RL.
The flow rates corresponding to 4 and 20mA can be set by the user via the SET 4 and SET20 tabs on the meter’s setup menus.
Note: As configured by the factory, any alarm state will force 22.8mA on the loop. This can be changed to 3.2mA – see Technical Bulletin, `iMAG4700/AG3000: Changing the 4-20mA Alarm’
Modbus® Serial Communication Configuration (factory configured).
These connections provide a half-duplex, isolated, RS485 serial communications port using the Modbus® messaging protocol. The TXD connection is the transmitted data output from the meter and RXD is the received data input to the meter. See Seametric’s Modbus® Interface Description, LT-103393 (available at www.seametrics.com) for supported Modbus® message protocol and electrical interface specifications.
A 120-ohm termination resistor is built into the Modbus® option board but is shipped in the unused position. To engage the termination resistor, move the jumper on JP1 from position 3-4 to position 1-2.

Power Indicators
A power indicator is displayed in the lower left of the main display window.
Any meter powered from an external power source will display a power plug icon when running on external power. If the connection to external power is lost, the meter will switch to the backup battery and the power icon will switch to a battery symbol.
OK on the battery indicator means battery voltage is above 6.4 volts.
LO on the battery indicator means the battery is low and should be replaced soon.

Battery Powered Units
To `wake up’ a battery powered meter, you may need to
hold the up arrow for 5 seconds and release. If the meter
does not wake up on the first attempt, repeat the 5 second hold.
it may take up to a minute for the displayed rate to take
full advantage of the DAMP filter. When starting with an EMPTY PIPE it may take at least 30 seconds to register
any flow.
The iMAG 4700 meter can come configured with one 7.2V `D’ size replaceable battery pack. The battery powered meter comes standard with scaled pulse output, while Modbus output can be selected as an option. The scaled output for the battery powered option has a maximum pulse rate of 150 pulses/second. Be sure to set your P value such that the meter will function properly over the flow range in your 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. (A sample period of 5 seconds–5 year battery life–is the default.)
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.

DAMP Settings for Battery Units
If SAMP (sample period) is set to less than one second, the DAMP value represents the number of seconds (plus one) used in the rolling average for the display. For example, if DAMP is set to four, then when the meter begins to show a flow rate, the rate displayed is the average of all the readings taken in seconds one through five (4 plus 1).
If SAMP (sample period) is set to one second or longer, the DAMP value represents the number of sample periods (plus one) used in the rolling average for the display. For example, if SAMP is set at three seconds and DAMP is set to four, then when the meter begins to show a flow rate, the rate displayed is the average of samples one through five (4 plus 1). Note that depending on the settings selected,
NOTE: If a large percentage of the meter’s life will be spent below 0.5 meters/second and above cutoff, battery life will be reduced.
BATTERY LIFE WITH MODBUS® OPTION!
IN THIS CONFIGURATION THE METER COMES STANDARD WITH PULSE OUTPUT. WHEN ORDERED WITH THE MODBUS® OUTPUT OPTION, BATTERY LIFE WILL BE REDUCED TO 1 YEAR, OR GREATER, BASED ON USAGE. REDUCE POLLING FREQUENCY AND SAMPLING PERIOD WILL AFFECT BATTERY LIFE.
