Instruction 

Photo Example

1. Connect the antenna to the FM250

• Connect the antenna using the SMA connector on the FM250 gateway. 

2. Power on the FM250

• Press and hold the green button on the FM250 device for at least 3 seconds. 

Note: If the LED lights fail to illuminate, please refer to the appendix for instructions on resetting the device to shipping mode.

The LED beneath the blue button will illuminate:

• Yellow blinking: Searching for signal.
• Green blinking: Establishing connection.
• Solid green: Connected to the cellular network.

3. Wait for 1 minute, allow the FM250 time to complete the initial communication with the server before proceeding.  

4. Verify connection via Retool App:

• Verify Comm matches today's date and time.
• Cell Signal: Good, no less than Medium.
• Battery: Good
• FW Version: Good

Note: Contact Pro Services support if the device fails to communicate, has a dead battery, or requires a firmware update.

Meter Box Installation:

1. Install the hardware to minimize interference with the meter register, ensuring the device is situated out of the way of valves and shut offs.
2.  Take care to prevent the entanglement of the FM250 sensor with any existing AMI or AMR cables.

Utility Vault or Inside the building:

1. Mount the FM250 device on an adjacent wall.
2.  Position the device as high as possible for the best signal.

Meter Box Installation:

1. Connect the antenna to the FM250 using the SMA connector on the gateway.
2. Place the antenna in the best location.
3. Stake the L-bracket into the ground. 

Utility Vault or Inside the building:

1. Mount the antenna to the highest point achievable within the meter environment. 
2. Extend the antenna if necessary. 

Instruction

Photo Example

Note: The flat side of the sensor should interface with the meter register to ensure accurate flow monitoring. 

1. Apply Pipe Insulation Tape

• Cut a 24" piece of insulation tape.
• Apply the tape to the back of the sensor. 

2.Install the sensor on the meter register.

• Attach the sensor to the register.
• Secure it with pipe insulation tape. 
• Go around the register 2X with the tape. 

3. Secure the sensor with a hose clamp.

Note: Install the hose clamp as high on the sensor as possible, near the cable union. Avoid the lower half of the sensor when possible, as over tightening of the hose clamp may cause damage to the sensor chip. 

• DO NOT over tighten or torque the hose clamp.
• Hand tighten the hose clamp ONLY. 

Best Practice: Install the sensor at the 3 o'clock or 9 o'clock position on the water meter register unless otherwise instructed. 

Neptune T-10: Place sensor at the 4 o'clock position on the meter register approximately ¼" - ½" up the register.

Locate an exterior hose bib, open a valve on the water meter's back flow preventer, or find a location inside the building such as a restroom where you can run a faucet with consistent flow for at least 3 minutes. 

1. Run water for approximately 3 minutes
2. Confirm that the sensor is registering pulses in its present position on the meter. Proceed to Step 2 if pulses are being detected.

Troubleshoot: If the sensor is not collecting pulses, relocate the sensor by 1 hour" on the meter register. For example, if the sensor is currently at the 3 o'clock position on the register and is not collecting pulses, move the sensor to the 4 o'clock position and try again. 

1. Press and hold the green button on the FM250 for 3 seconds.
2. Take a photo of Base Meter Reading.
3. Record the time of the base meter reading. 

• In this example, the meter reading is 518757.

1. Press and hold the green button on the FM250 for 3 seconds.

2. Take  a photo of the Calibration Meter Reading.

3. Record the time of the calibration meter reading. 

• In this example, the meter reading is 518761.

           1. Press and hold the green button on the FM250 for 3 seconds.

2. Take a photo of the Verification Meter Reading.

3. Record the time of the calibration meter reading. 

• In this example, the meter reading is 518766.
