    lowrance fuel flow meter and sensor-gctid778900

    now on my second in dash meter and third fuel flow sensor; model numbers LMF-200 meter and EP 10 sender. Has anyone had problems with these models???

    I installed the LMF-400 and 2 sensors part way thru this past season. Working great and seems accurate. Very sensitive to fuel flow changes during boat trimming.

        Mine are 7 years old no problem at all. I have the fluid level on one tank need one more for the other tank. Saves me having to tell the unit how many gallons I put in the tank.

          4 fuel flow sensors and 2 LMF 200 dash units and 2 paddle wheel speed sensors in one season. It will be out of warranty in march and if it quits again I will scrap the the whole thing and go with a different brand. So far I'm not impressed with Lowrance products or their customer service. The longest this thing worked was 2 days at a time and Lowrance customer service is sloooow at best on warranty replacements or even knowing their own products.

            Talking to Lowrance technical support is like talking to a 5 year old child, I probably spent over 4 hours total on the phone with these idiots and never got a straight answer or suggestion on what the problem might be. After about 30 minutes they pretended they couldn't hear you and hang up so you would have to call back and start the whole process again this happened 3 or 4 times and each time they give you a new incident number so now I have 14 incident numbers. Okay now I'm done with rant.

              The sensor has to be installed after a good fuel filter and installed vertical. If the filter isn't filtering well it will damage it or if your fuel lines are deteriorating it will damage the sensor. If not vertical it won't work properly

                My flow sensor is installed in the vertical position after the spin on filter/separator assy. I even sent them pictures to prove it was properly installed. After the 4th failed flow sensor they thought maybe the dash unit was causing the failures. I asked them if this could be the cause from the get go but they were reluctant to replace it and I finally received the replacement head and 5th flow sensor after the boat was put up for winter storage. I will install the new parts in the spring and hope for the best.

                  I have added spin on fuel filters at the tank and then have my fuel flow sensors and then the hoses going to the second fuel filter on the engine at the fuel pump so my sensors are between two filters and I've never had a problem

                  If yours are after the filter on the engine on the pressurized side between the fuel pump and the carburetor that might be part of the problem

                    exactly the same setup i have , and working great since installation 2 years ago.

                    The flow meter is connected directly to my NMEA network and is displayed on my Raymarine MFD instrument.

                      Nope on the suction side of the pump after the filter with all new USCG approved fuel lines.

                        My guess is that being too close to the pump and not having a filter to buffer the effects of the pump may be part of the issue if sensors are failing.

                        I have:

                        Tank

                        18" Hose

                        Spin on Water Separating fuel filter

                        36" hose

                        Fuel flow sensor

                        18" Hose

                        Engine mounted filter

                        Fuel Pump

                        Hard pipe to carb

                        Carb

                        Lengths are approximate and vary port vs starboard.
