Revision 1.2 Page 7 ® ® Max. return flow rate = 5 gall ons / 0.25 hours = 20 gallons per hour Now, add in the engine’s consumption fuel rate at this RPM, which should be readily available from the manufacturer’s documen tation for the engine, and calcul ate the maximum supply flow rate as follows: Max.
FFM100 User’s Manual Page 8 Revision 1.2 1.6.7 Choosing a Fluid Flow Se nsor Mounting Location Choosing a proper mounting location for fluid flow s ensors is critical to obtaining accurate tank level measurements. Because of the positive displacement design of the FFM100 sensors, no pulse dampening or flow straightening is necessary .
Revision 1.2 Page 9 ® ® 2.3 Mounting the FFM100 Attach the FFM100 securely to the vessel usi ng the included stainle ss 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.

Revision 1.2 Page 15 ® ® 3.4.9 Configuring Channel #0 Temperature Label Program this parameter with a te xt string which identifies the par ticular temperature parameter being monitored by this channel. Maretron display products will display this label text when you are selecting data to display.
FFM100 User’s Manual Page 16 Revision 1.2 is programmed with the appropriate value for thermal expansion coefficient of the fluid being measured. The default value of this field is (0. 083%/°C), which is appropriate for diesel fuel. The configuration tools have predefined values for common flui ds: diesel, engine oil, gasoline, and water.
Revision 1.2 Page 17 ® ® • Ensure that the unit is mounted securely an d cannot be moved relative to the mounting surface. If the unit is loose, ti ghten the screws holding the cable ties. • Check the security of the cable connected to the NMEA 2000 ® interface and tighten if necessary.
