iMAG 4700 Municipal Industrial Magmeter

Note: These instructions cover the iMAG 4700. For details on the iMAG 4700p or 4700r, see the iMAG 4700p or iMAG 4700r Municipal/Industrial Magmeter Instructions.

GENERAL INFORMATION

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 up to 10 feet (3 meters) continuously. 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. Built-in data logging is available as an option for secure flow logging. 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. In addition, 4-20mA passive current loop, and Modbus® protocol outputs are optional, although battery life will be reduced if ordered on battery-powered units.

INSTALLATION

Straight Pipe Recommendations (X = diameter)

NOTE: These configurations are to be used as general guidelines and do not cover every possible installation. A combination of two or more obstructions will require additional straight pipe. If there is any concern about the length of pipe required for a specific application, please contact your local dealer.

Full Pipe Recommendations

Positioning the Meter

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).

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.

CAUTION: In chemical injection applications, install chemical injection point downstream of the magmeter, or far enough upstream to allow complete mixing of fluids.

Installing Gaskets

GASKETS
Gaskets are required at all junctions.

1. Be sure all mating surfaces are smooth and free of debris.
2. Install Seametrics provided gaskets, or equivalent, on each end of the meter as shown in the diagrams below. If using grounding rings, install one gasket on each side of the grounding ring.
3. Failure to install gaskets will void the warranty.

Tightening Flange Bolts

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. Over-tightening can cause serious damage to the flow meter.
4. Recheck after 24 hours, adjusting if needed.

Caution: Improper tightening sequence can cause serious damage to the flow meter.

• Do not tighten one side at a time.
• Do not tighten each bolt completely at one time.

Equalization and Grounding

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.

Plastic Pipe and Electronically Noisy Installations. When the iMAG 4700 is installed in plastic pipe or in an electrically noisy system (near a VFD etc.), grounding rings are recommended. As shown in the diagram below, the equalization wires should be solidly connected to the grounding ring tabs instead of the flange bolts as in metal piping installations. Where lightning is a threat, or in severe electrical environments, an optional connection to a nearby equipment ground or ground rod may be advisable.

CONNECTIONS

iMAG4700 General Cable Information
The iMAG 4700 meter has two power/output cables that can be installed. The 4-pin cable contains the wires for DC power and pulse output. The 8-pin cable contains the wires for DC power and pulse, 4-20 mA or Modbus® output options when ordered. See diagrams below for details. The iMAG 4700 is available in either Battery or external DC versions.

WARNING: BACKUP BATTERIES ARE NOT INTENDED AS A PRIMARY POWER SOURCE OF A MAINS (DC or AC) CONFIGURED METER.

Option IDs

• O ID POWER SOURCE / OUTPUT(S)
• BXX = BATTERY POWER / PULSE SCALED
• BXS = BATTERY POWER / PULSE SCALED / MODBUS®
• D1X/D2X = DC POWER / PULSE SCALED
• D1L/D2L = DC POWER / PULSE SCALED AND 4-20mA
• D1S/D2S = DC POWER / PULSE SCALED AND MODBUS®

CONFIGURATION

Pulse or Digital Output Application – Sourcing Mode (Recommended for Rin < 30kΩ)

Pulse or Digital Output Application – Sinking Mode (Recommended for Rin > 30kΩ)

Analog (4-20mA Current Loop) Output Application

• Minimum resistor value is (100 x Vs) ohms. Higher resistances maybe used depending on frequency and cable length. Longer cables and high frequencies require lower resistance.
• Resistor RL converts 4-20mA current to voltage for voltage input-only devices.

Cable Shield. In general, the cable shield and its bare drain wire should be left unconnected at the user equipment end of the cable to minimize “ground loop” problems.

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 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 SETP tab on the meter’s setup menus. 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. 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.

If Pulse Output is Inconsistent. The PDAMP filter may need to be increased.

Pulse Width Timing. The unit and value of SETP must be chosen to keep the duration between meter pulse outputs to less than 500 seconds.

Pulse Timing in Battery Powered Units. The output pulse width in battery- powered units is short and varies with pulse frequency. (See table)

Lower frequency output pulses (1 pulse for some particular number of gallons) can also be set. Any output frequency can be determined by:

• Rate (units/minute) ÷ SETP (units/pulse) = pulse/minute
• Hz = pulse/minute ÷ 60 seconds / minutes

Output Pulse Width of Battery Powered Units

Output Pulse Frequency

| Output Pulse Width as a Percentage of the Pulse Period

(Pulse period = 1000 milliseconds/frequency)

Zero to 1 Hz| Multiply the pulse period by 0.01| = Output Pulse Width (ms)
1 to 20 Hz| Multiply the pulse period by 0.05| = Output Pulse Width (ms)
20 to 100 Hz| Multiply the pulse period by 0.1| = Output Pulse Width (ms)
100 to 150 Hz| Multiply the pulse period by 0.15| = Output Pulse Width (ms)

Example: If frequency = 20 Hz then the pulse period = 50 milliseconds and pulse width = (.05 x 50 milliseconds) = 2.5 ms

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.

Special SUBMENU for Further Options

The EXIT tab in the MAIN MENU has a second function. If, instead of using the hold and tap up sequence to return to the HOME screen, you tap seven times, you will be redirected to a SUBMENU screen from which you can access several more options. Navigation in this SUBMENU is the same as for the MAIN MENU. Whenever you wish, go to the EXIT tab in the SUBMENU and perform the hold and tap sequence to return to the MAIN MENU.

• INFO: Meter model number, serial number, and firmware version.
• COMM: Modbus® baud rate and parity.
• MBID: Modbus® address
• SAMP: Sample rate (Battery powered version only.)
• EXIT: Return to MAIN MENU or enter next submenu.

To Change a Passcode and Decimal Places
The iMAG 4700 has a passcode system for restricting access to the menus. The AG3000 comes from the factory with the passcode set to 000000. When a user attempts to enter the menu system (see details on page 16), the passcode entry screen will be displayed.

The default passcode is 000000. If a different passcode has previously been set, then the user must enter that passcode at this time. After entering the passcode, or leaving it at 000000 if using the default passcode, the user does the tap and hold sequence to move into the menu system. To change the passcode, you must use the THIRD MENU screen. Access the THIRD MENU screen as follows:

• Enter the main menu system, as described above.
• On the main menu, tab over to the EXIT tab and tap the up arrow five times. A SUBMENU screen will display.
• On the SUBMENU screen tab over to the EXIT tab and tap up five times. The THIRD MENU screen will display.
• To set the PASSCODE, hold and tap on SETCD up and right then use the and to enter the new code.
• Hold and tap again to return to the THIRD MENU screen.
• Tab to EXIT, and then hold and tap to return to the SUBMENU.

To change the number of decimal places in the total

• To set the decimal point, hold and tap on SETD and then use the right to move the decimal point.
• Hold and tap again to return to the THIRD MENU screen.
• Tab to EXIT, and then hold and tap to return to the SUBMENU.

PDAMP
PDAMP is used to view or change the number of samples for rolling average of pulse output.

TEST
TEST allows the user to initiate a fully functional, artificial flow rate for the purpose of testing other connected equipment. When TEST is applied, all features of the meter will function at the stated flow rate (in gallons per second). For TEST to function, the meter must be filled (not EMPTY PIPE).

To enter a value into the TEST feature, navigate to the TEST tab and enter a flow rate value in the VAL screen (in gallons per second only,) then right to the VAL box and up to the ON screen. This will initiate the TEST feature. The next up would bring you to the OFF screen, but you can ‘hold and tap’ the arrows to return you to the sub menu while the feature operates.

After use, the TEST feature must be turned OFF. If the TEST feature is not turned OFF, the stated static flow rate (in gallons per second) will be shown any time the meter is full or in a flowing condition. Flow values recorded by the meter while the TEST feature is operating are permanently recorded in the displayed TOTAL. It may be useful to note that these values are only written to permanent memory every 15 minutes and cycling all power within this 15 minute time frame will return the meter to its previous total.

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. 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,

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.

Battery Life/Sample Period For battery (BX) powered meters only.

• Based on 75% battery capacity at room temperature with no option cards installed.

NOTE: If a large percentage of the meter’s life will be spent below 0.5 meters/second and above the 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.
