2.3 Mounting the FFM100
Attach the FFM100 securely to the vessel using the included stainless steel mounting screws
or other fasteners as shown in Figure 5 below. Do not use threadlocking compounds
containing methacrylate ester, such as Loctite Red (271), as they will cause stress cracking of
the plastic enclosure.

2.4 Mounting the Fluid Flow Sensor
Since the FFM100 supports different fluid flow sensors depending on the application, please
consult the installation instructions that are packaged with each sensor for detailed installation
instructions.
2.5 Connecting the FFM100
The FFM100 requires two types of electrical connections:
1) the fluid flow sensor connections, which are described in Section 2.5.1, and
2) the NMEA 2000
®
connection (refer to Section 2.5.2).
2.5.1 Fluid flow sensor Connections
The FFM100 fluid flow sensor connections are made by connecting to the 12-pin terminal strip
on the top of the unit. First, remove the four screws at the corners of the unit detaching the
splash guard from the unit. On the bottom of the splash guard, you will find a label detailing
the wire connection to pin number assignments, which are repeated in the table below.
