WATERCOMPASS FM300-US FLOW MONITOR: INSTALLATION INSTRUCTIONS 1/4 - 2”
Installation Overview
This installation manual is intendeded to
detail the process a contractor should follow
to install an FM300 Flow Monitor on-site, as
welll as outlining basictroubleshooting steps.
The FM300 Flow Monitor is a non-invasive
flow monitor that reads usage data from
an existing water pipe with ultrasonic
techinology, continuously moitors for
leaks, and tracks ongoing water usage.
There are 3 phases to the installation proess.
WaterCompass Data Collector installation,
Flow Monitor installation, and WaterCompass
Data Collector Configuration.
You don’t need to turn off the water or
cut any pipes to install the flow monitor.
After installation, the flow monitor will be
able to read flow on the supplyline and the
WaterCompass Data Collector will establish
a cellular data connection to upload usage
data to the WaterCompass dashboard.
If you have any questions or issues
when installing the FM300, please call
Contractor Support at 800-362-8775.

Wall Mounting Instructions
Use the template enclosed with the Water
Compass Data Collector for assistance when
mounting the enclosure to a wall.
Locate the 2 mounting holes on the back of
the enclosure. The two upper mounting holes
are keyholes. This design allows the two upper
fasteners to be installed first. The enclosure is
then slipped over and pushed down to complete
the installation.
A third mounting hole can be found in the center
of the enclosure. A typical mounting height for
a wall-mount enclosure is between 41” and 48”
above a finished surface.
Before drilling, verify that the controller is level and
vertically straight before installing.
1. Remove the outer door for access to the
interior of the enclosure. Slide it upwards, then
place it in a location to prevent damage.
2. Mark and drill new mounting holes using the
paper template, then drill appropriately sized
holes with a hammer-drill as needed. Use
plastic inserts and mounting screws (taped
to the controller with the enclosure keys) to
secure the controller.
3. Hang the enclosure on these fasteners and
verify the enclosure is mounted level both
vertically and horizontally.
4. Locate the third center mounting hole and
insert the last fastener. Tighten all fasteners to
the enclosure to secure to the vertical surface.
Step 1: Mount the WaterCompass Data Collector Enclosure

Step 2: Connect the WaterCompass Data Collector to AC Power
1
The WaterCompass Data Collector incorporates a dual voltage power supply and can be connected
to a single phase 120 V ac or single phase 220 V ac source. Please refer to the 120 V ac or 220 V ac
diagrams on pages 5-6 for proper connections.
The input side of the transformer has 5 color-coded conductors. A label is attached to the
transformer body with identification for each conductor. Two of the conductors (specific to 220 V
ac connections) have been terminated with wire nuts, shortened and tied together with a zip-tie
to avoid confusion for 120 V ac installations.
Do not remove the wire nuts from the 220 V ac connections, as it may cause a short if removed.
1. Confirm that the WaterCompass Data Collector has been securely fastened to a flat, vertical
surface before starting this work.
2. Open the enclosure door and locate the transformer mounted to the chassis. Thread an
approved weatherproof plastic or galvanized metal junction box onto the 1/2” nipple and
secure with a conduit locknut.
3. Connect approved conduit to the underside of the junction box.
4. Pull the required number of conductors and terminate them in the junction box with sufficient
length so that wire nut connections can be made.
5. Remove approximately 1/2” of the wire insulation of the conductor and use an appropriately
sized wire nut based on the number of wire connections being made. Adhere to local and
state electrical codes.

WATERCOMPASS FM300-US FLOW MONITOR: APPENDIX A
Appendix A: Selecting an Installation Location
How to Select an Installation Location
Some important factors must be considered BEFORE installing the FM300-US Flow Monitor. Read and follow the
guidelines below to ensure that the flow monitor is installed in just the right location to deliver the results you need.
• Choose a location indoors
• Choose a location that captures all the flow being monitored
• Install on a pipe that is always full of water
• Ensure that the monitor has direct contact with the pipe
• Install in a location that is free of turbulence
• Install in a room where there is 120V power
Choose a location that captures all the flow being monitored
Whether you want to monitor an entire building or just a floor of a building, you will need to install the device in a place
indoors that captures all of the flow entering the section of building that you want to monitor.
For example, if the objective is to monitor the flow for an entire building, the device should be located on the pipe
entering the building from the water source. If the objective is to monitor a specific floor of a building, the device needs
to be installed on the pipe supplying all the water for that floor.
Install on a pipe that is always full of water
The device needs to installed in a location where the pipe is always filled with water. Be aware of situations where low
flow may allow the pipe to be only partially full:
Ensure that the monitor has direct contact with the pipe
The flow monitor needs to be installed directly on the pipe. Do not install the device on top of insulation or in areas that
contain rust or seams.
Install in a location that is free of turbulence
Changes in pipe size and direction can create turbulence in the water and stop the monitor from accurately reading
flow. Select an installation location that will ensure adequate distance upstream and downstream of the monitor to
allow any turbulence to settle before passing the flow monitor.
Be sure to select a location that is:
• Far enough downstream to allow turbulence to settle
• UPSTREAM of pressure regulating devices
• Far enough away from sources of large pulsation (like from a pump)

18 800 362 8774 | hydropoint.com | [email protected]
WATERCOMPASS FM300-US FLOW MONITOR: APPENDIX A
You can use the chart below to help ensure that you are leaving enough space upstream for proper flow.
You will need a caliper and a tape measure to determine the diameter and length of existing pipe.
The Length (L) should be greater than X times the diameter of the pipe
based on the specific pipe change described in the chart.
For example, on a 2” pipe the monitor’s best section of pipe is directly downstream of a 90°
elbow. We’d look for at least 10x2” or 20” of pipe between the end of the bend and the
beginning of the monitor to allow for the turbulence caused by the elbow to settle.
Install in a room where there is 120V power
The WaterCompass FM300-US Flow Monitor runs on DC power. It is best to install the device in
a room where there is a power outlet or where power conduit can be tapped into for use.
The DC supply wire and the two-wire can run in parallel and inside the same outer jacket.
The DC supply wire cannot have more than 25ohms* of resistance: 12.5 out, 12.5 back.
Wire lengths for power can be extended according to the gauge of the two wire that connects
the flow decoder to the flow meter. Below is a chart listing wire gauges and length limits.
Wire Gauge #18 #16 #14 #12
Wire Length 1,900 3,100 5,000 8,000
