Overview
The Series IEF Insertion Electromagnetic Flow Transmitter is an adjustable insertion flowmeter featuring electromagnetic technology that accurately and reliably measures fluid velocity in addition to providing several continuous signal outputs. This series is specifically designed to offer superior performance paired with simple installation and use. One unit is adjustable to fit pipe sizes from 4" to 36" (101.6 to 914.4 mm), and offers several output options including selectable BACnet MS/TP or Modbus® RTU communications protocol over 2-wire RS-485 in addition to the standard analog, frequency and alarm outputs.

Recommended Tools
- (2) 12" (300 mm) adjustable wrenches
- (1) 12" (300 mm) pipe wrench
Setup: Selecting Installation Location
- Although the unit may be installed in any orientation, the ideal mounting position is on the side of the pipe (2 o'clock or 10 o'clock position) as this generally minimizes possible air or sediment interference with the Series IEF.
- Note: When installing a unit with an integral display select an installation location that allows for clear viewing of the display and proper earth ground.
- Insert the IEF in a pipe via a threaded Tee, Saddle, or welded integrally reinforced branch connection outlet fitting.
- If a Hot-Tap option is required, use a 1-1/4" valve kit with proper mounting hardware available in Model A-IEF-VLV-BR or A-IEF-VLV-SS. A 1" (25.4 mm) hole in the pipe is required for proper installation.

Included with the Flowmeter
Carefully unpack the shipping container of your new Series IEF Insertion Electromagnetic Flow Transmitter and remove the following items:
- (1) Series IEF Insertion Electromagnetic Flow Transmitter
- (1) A-IEF-INGD Installation Alignment Kit:
- (1) Alignment Scale
- (2) Alignment Rods
- (2) Thumbscrews
- (1) 3 mm Allen Wrench (not shown)

Installation
- To prepare the meter for installation, mount the provided alignment scale to the side of the meter with the two provided thumbscrews. The thumbscrews are to be inserted through the alignment scale slots and into the holes in the side of the lid as shown in Figure 4, finger tighten only. Be sure to orient the alignment scale as shown in figure below. Actual scale setting determined in next step.
- Diagram showing the alignment scale mounted to the Series IEF lid with thumbscrews, indicating the use of the enclosure gap as an indicator line for scale setting.
- For Custom Configured Models (-CC Option): Locate the configuration tag attached to the Series IEF to identify the value of the alignment scale setting. Position the alignment scale such that the scale setting is lined-up with the seam of the enclosure as shown in Figure 4. Minor scale marks are in 1/20ths. Securely tighten the thumbscrews. Refer to Preparing the Unit for Installation section.
- For Field Configurable Models: A display is required (-LCD option or accessory A-IEF-DSP) and needs to be powered via normal field wiring or with the AC wall adapter accessory A-IEF-PA (A-IEF-DSP and A-IEF-PA are also available in the accessory setup kit A-IEF-KIT).
- When using the AC wall adapter and the cable is supplied, connect the red (positive +) and black (common -) wires of the cable bundle marked "A" to the open terminals of the AC wall adapter. This will provide temporary power to the meter to complete the installation set up.
- For field wiring refer to the wiring chart tag attached to the Series IEF to identify the terminal block pins for positive (+) and common (-) connection.
- Unscrew the four captured cover screws using the supplied 3 mm Allen wrench to remove and set aside enclosure cover.
- Insert one connector of the ribbon cable supplied in the setup kit into the connector labeled "Display" in the middle of the unit. Be sure to orient the keying feature/tab. See Figure 5 below:
- Illustration of the Series IEF transmitter with the enclosure cover removed, showing the ribbon cable connector labeled 'Display' and the keyline feature.
- Plug the other end of the cable into the bottom of the supplied portable display being sure to orient the keying feature/tab as shown:
- Illustration showing the connection of the portable display cable to the Series IEF transmitter, highlighting the keyline feature for proper orientation.
- Apply power to the unit and the display will turn-on automatically. Follow the on-screen directions for entering the necessary parameters to setup the unit and obtain the alignment scale setting value.
- NOTICE: Precise pipe measurements are required for high performance installation. The A-IEF-KIT includes setup display A-IEF-DSP, thickness gage UTG and measuring tape A-IEF-MSTP used to obtain these measurements. When the precise pipe measurement information is known select Option 2 High Performance setup in the Install Kit option of the display selection.
- NOTICE: When using measuring tape A-IEF-MSTP to measure pipe circumference use the 100ths side to measure the circumference of the pipe without insulation.
Preparing the Unit for Installation (Refer to Figure 7)
- Apply appropriate sealant to the process collet (5) threads such as application suitable sealant tape or paste.
- Install the process collet (5) in valve (6) then tighten by hand.
- Tighten the process collet (5) with a wrench using the hex geometry until snug.
- NOTICE: Use two wrenches, one to hold the valve and another wrench to turn the process collet.
- Slowly open the valve handle (7) checking for leaks.
- If leaks occur around threaded connections, close the valve and tighten those connections.

Sensor Alignment
A depth and flow alignment installation tool is provided to ensure proper depth insertion and flow alignment. To set the insertion depth verify the alignment scale has not moved from its original setting based on the alignment scale value set previously.
Loosen compression nut (4) to allow the shaft (3) freedom to travel up and down and rotate inside the process collet (5).
Install Depth and Alignment Rods
- Remove alignment rods from sides of alignment scale by sliding them out.
- Insert the two rods into the alignment scale as shown.
- Diagram illustrating the sensor alignment process, showing the alignment scale, flow alignment rod, and depth rod.
- Rotate the transmitter so the pipe alignment rod is parallel with the flow in the pipe.
- Slide the shaft (3) down into the process collet (5) until the depth rod contacts the pipe. If pipe insulation is present press the rod through the insulation.
- a. Tighten the nut (4) to 15 ft.-lbs (20.3 N m).
- b. Remove the flow alignment rod and loosen the thumbscrews to slide the alignment tool up to allow removal of the depth alignment rod. Store both rods in the storage slots on the sides of the alignment scale. Tighten thumbscrews and leave alignment tool mounted on unit for storage.
Grounding
Metallic Pipe
For proper operation the instrument must be earth grounded.
- Connect a ground wire to meter housing via the ground lug on the housing collet.
- Connect the ground wire to a known earth ground.
- If the pipe is grounded, connect the ground wire to the metal pipe using suitable devices such as grounding clamps.
Diagram illustrating grounding for metallic pipes, showing a ground wire connecting the meter housing to a grounding lug and then to a metal pipe via a grounding clamp.
Non-Metallic Pipes
- Connect a ground wire to the transmitter housing per the ground lug on the housing collet.
- Connect the ground wire to a known earth ground.
- Ground the fluid to earth.

Power Supply
Choose a power supply with a voltage and current rating sufficient to meet the power specifications under all operating conditions.
If the power supply is unregulated, make sure the output voltage remains within the required voltage range under all power line conditions.
