Before starting the setup, ensure you have the following:

  • An existing WeatherTRAK.net login with Admin-level permissions.
  • The serial number of the device(s) you are setting up.
  • Account access for New Accounts. Refer to the appendix for instructions on updating permission settings.

    • Click the left arrow to assign the flow sensor to the water meter.
    • Confirm that the WeatherTRAK OptiFlow XR Flow Sensor is correct and click Save.

Step 5: Assign a Usage Group

Assigning a usage group to the monitoring point ensures that the data collected by the flow monitor is categorized correctly.

  1. Navigate to Usage Groups:
    • In the Admin Tool, go to the WaterCompass section and select Usage Group.
  2. Search for the Site:
    • Use the search bar to find the site where the water meter is located, then click Edit.
  3. Select the Correct Usage Group:
    • Choose the appropriate usage group for the new water meter. Options include:
      • Indoor Usage

Step 6: Verify the Data 

Once the FM300 Data Collector is configured, you should verify that the WaterCompass.net dashboard is receiving incoming data from the newly set up device.

  1. Wait 20 Minutes:
    • Allow 20 minutes for the data to start populating.
  2. Navigate to WaterCompass.net:
    • Go to WaterCompass.net and select the customer's account.
