I have a 2001 Mercury OptiMax 225-HP. I'm going to install a fuel flow meter. What the best way to go? Floscan, or Navman? Which one is more reliable, and trouble free? I have a Floscan in my Shamrock. It's mounted in a tachometer cup, and removable, so I just need another sensor. I like the extra features of the square model Navman [NAVMAN 3100 FUEL], but I'm also considering the round econo madel [NAVMAN 2100 FUEL], too. Any input, or advice is much appreciated.
Thanks
Rick

I have a Navman and it stopped reading after about 60 gallons of gas went through the transducer.

Doesn't the Opti have smartcraft capability?

Phatwhaler: look for a bit of something in the transducer thats
jamming the paddlewheel, or a bad wire.

I have a NAVMAN 3100 FUEL. I have written about its performance in several prior articles. In particular, see

as well as

The most significant different between Flowscan and Navman products from what I can tell is the price.

In the event you have not seen it, Lowrance has recently introduced a fuel flow meter as well. NMEA-2000 compatible and reasonably priced. Search for "Lowrance LMF-200"

I am interested in monitoring fuel flow in the near future. I see that Lowrance LMF is advertised as NMEA 2000 compatible.

I have a Standard Horizon CP 175 (I think I got that model designation correct). The owner's manual indicates that the unit is NMEA compatible.

Is NMEA 2000 compatible with NMEA? I would like the GPS to talk to the fuel flow instrument so I can have real time miles per gallon figures.

Thank you,
Doug Vazquez

Doug--Your older Standard Horizon chart plotter and GPS has a NMEA-0183 input/output. This is not compatible with NMEA-2000.

NMEA-0183 is a serial data scheme with one talker and many listeners on each dedicated circuit. NMEA-2000 is a modern serial data bus where many devices can all talk and listen to each other on single network circuit.

Re the LOWRANCE LMF-200 gauge and fuel flow monitoring sensors: this is also a very good way to build a fuel flow monitoring system. The pricing from Lowrance is very attractive, and the NMEA-2000 nature of the system permits it to be connected to a vessel network.

With the Lowrance system, you build your own fuel monitoring insturment:

LMF-200 --$90

The LMF-200 is a 2-inch NMEA 2000® Multifunction Gauge. Capable of showing data in Single Digital, Dual Digital, Single Analog, Trim Tab, Engine, Diagnostics, Engine Trim and Engine Synchronizer formats. Capacity for up to 16 pages in the queue. Page scrolling from 1 to 60 seconds. Dash Light Sense, Backlight, and Reverse Video control of itself and other gauges over the bus.

ELECTRONIC PROBES

EP-10 Fuel Flow Sensor--$50

I believe you can buy these two devices in a package with all of the other accessories needed to build a simple NMEA-2000 instrumentation network for less than you can buy a NAVMAN 2100 or 3100.

Jim,

I guess I would have to upgrade my GPS system if I wanted real time miles per gallon data using the Lowrance LMF 200.

If I remember correctly, Standard has a fuel flow instrument that is identical to the Navman. Would the Navman 3100 would give me that capability using my current GPS system?

Thank you,
Doug Vazquez

This excerpt from the LMF 200 instruction manual should resolve any confusion about what devices can be connected to it:

"This gauge will only work with a NMEA 2000 network. It MUST be
connected to a NMEA 2000 network or it WILL NOT function."

DeeVee, I suspect the Navman 3100 is just when you want. See Jimh's discussion here: http://continuouswave.com/ubb/Forum6/HTML/000697.html

I agree, the Navman 3100 is the one I need.

Thanks,
Doug Vazquez
