Product Description
The FlexNet® wireless transmitter for gas AMR
applications permits offsite meter reading by way of a
fixed base radio network. In addition to solving meter
reading problems such as lockouts, entering unsafe
meter locations, "curbside" reading estimates,
estimated billing, and errors associated with manual
meter reading methods, a fixed network provides
benefits such as daily reads and status alerts.
A significant advantage of the module is its powerful one- Watt transmitter. The long range enabled by the
strong signal and high receiver sensitivity, minimizes the number of base station receivers and provides
optimal coverage at minimal deployment and ongoing costs. FlexNet transmitters are powered by a
replaceable Lithium battery pack, with an expected service life of over 20 years.
The transmitter is enclosed in a durable polycarbonate casing with a clear cover that enables reusing the
original meter index. The module consists of a narrow band transmitter, magnetic sensors, and mechanical
meter interface that includes a shaft with a magnet. A handheld terminal is used to initialize operation. The
module monitors the meter and sends data to the base station receiver network at predefined and
programmable intervals. Transmitter messages contain meter reading data, status and relevant parameters
such as index pressure and the number of dials. Messages are routed to a database, where the data gets
formatted for export to billing, marketing and customer service systems.

Transmitter Mounting Instructions
FlexNet 100G-FL, 200G-FL and 300G-FL
See the appendix for descriptions of the screw kits and tools required for mounting the AMR transmitters.
Remove Index Cover
1. Use a small, flat screwdriver to punch out the snap seals covering the index cover screws.
NOTE:
If two (2) or more screws shear off during the cover removal (or were previously sheared off), the meter will need to be replaced by
a qualified utility representative. Reinstall any index cover screws that were removed and cap with seals if possible. Enter the
appropriate information in the Mint HHT
2. Remove the index cover screws.
3. Remove the index cover.

Remove the screws securing the index to the meter.
Carefully, remove the index from the meter.
Remove any debris from the index.
Inspect the index for proper operation by turning the input shaft and verifying that the gears turn freely.
Inspect the index for any missing or broken hands.
Use a putty knife to scrape away any remaining gasket material.
Mount Transmitter

4.
Align the transmitter’s shaft with the gas meter’s male/female wriggler.
Place the AMR Transmitter on the gas meter.
Adjust the transmitter shaft’s position
Ensure the shafts are aligned by holding the transmitter in place and gently rotating the transmitter’s
shaft with your other hand.
5. Loosely attach the transmitter to the meter using the transmitter mounting screws
6. Check shaft alignment.
NOTE:
If two (2) or more screws shear off during the cover installation, the meter will need to be replaced by a qualified utility
representative. Reinstall any index cover screws that were removed and cap with seals if possible. Notify the utility of the
condition of the meter in accordance with your company policy.
7. Tighten the transmitter mounting screws.

Loosely attach the index to the transmitter using the index screws.
Align the index’s male/female wriggler with the transmitter’s shaft, and adjust as needed.
Center the index in the transmitter, and ensure there is no binding between the shaft and the wriggler.
Secure the index screws.
Install the new index cover.
Align the gasket with the transmitter.
Use care when working with a power screwdriver to insert screws in the plastic Transmitter box. Over
tightening will damage the box and/or weaken the contact. Failure to comply with this caution can result in
damage to the equipment.
7. Secure the cover to the transmitter with the index cover screws.
8. Align and insert the two snap seals into the index cover using a ¼” nut driver until the snap seals are
fully seated.

Pulse Output Identification
1. If the output is a ‘dry contact’ pulse (i.e., magnetic relay, reed switch), use both wires.
2. If the output is an electronic pulse:
a. Connect the ‘plus’ wire, to the red wire from the transmitter.
b. Connect the ‘minus’ or ground wire to the black wire from the transmitter.
Mount Back Plate
NOTE:
When locating a place for the transmitter, consider:
• The wire lengths
• The convenience of wiring and ability to properly secure the wires
• That a high spot is preferable for optimal radio coverage
• The proximity (<6”) of the transmitter to metallic objects (not including the pipe on which
the transmitter is mounted)
1. Locate an appropriate spot for mounting the transmitter.
2. Secure the back plate to the wall with the mounting screws, or to the pipe using the pipe clamp. The
pipe clamp can be horizontal or vertical as long as the back plate is horizontal.
Mount Transmitter
1. Before mounting the transmitter, use the HHT to ensure that the transmitter is functioning properly.
Refer to the Gas AMR Installation HHT (Mint) User’s Guide.
2. Secure the transmitter to the back plate using the mounting screws.
3. Ensure that the transmitter is completely secure and horizontal.
Splice Wires
1. Strip the wires so that approximately 2" of the wires are exposed.
2. Insert two matching wire ends, as identified in Step 2 of “Pulse Output Identification,” into a
UY-2 gel-cap.
3. Crimp the gel-cap using the 3M Scotchlok® E-9Y steppe-jaw crimping tool until the cap releases the
waterproof gel,
4. Ensure the splice is secure by gently pulling on the gel-cap while holding the wires.
5. Repeat Step 1 through Step 4 for the remaining connection.
6. Secure any unused connections with UY-2 gel-caps.
If any of the wire connections are not being used they should be capped at the end with a UY-2 gel-cap.
This is to prevent water from getting into unused wires.
7. Secure excess or loose wiring.
8. Mount index cover on transmitter and secure with the index cover screws.
9. Align and insert the two snap seals into the index cover using a ¼” nut driver until the snap seals are
fully seated.
Initialize Transmitter
Use a Sensus handheld terminal (HHT) to initialize the transmitter.
