fuel monitor

[pogden]

How do the fuel monitors work---Navman, Floscan, etc.??
I would like to get one but I'm not sure which one ?

I did a search and it seems I have the Navman, Standard Horizon, Floscan, to chose from.

And what do I need to get with it...tank sender unit and guage? Is there anything else? I would like it to be as simple as possible.

you should swing by a dealer that carries the various brands and see which one suits you best. Posing the question you did on an internet boating forum is like asking whether Ford or Chevy is better - you will get ardent fans of each claiming that their brand is best.

Good luck [img]/images/graemlins/smile.gif[/img]

Pogden,
If you have a yamaha you can also buy the yamaha fuel management gauge for your motor. Beware it is very expensive. A good friend of mine paid about $1400 for his. His boat has twin 250 carb'd motors. The gauge is pretty cool because you can toggle between either motor (instantaneous gallons per hour) or total of the two. Its also got a sync function to sync the rpms. The yamaha gauge is digital and matches the other gauges. Hope this helps. -Will

Thanks Mark and Will,

After I hit the submit button I thought that was a pretty broad question(and kinda dumb question) [img]/images/graemlins/blush.gif[/img]. A friend has a Navman I think I will just ask him. [img]/images/graemlins/grin.gif[/img]

I bought the Navman 3100. It's cheaper and has more functions than the Flowscan.

This diagram shows you the parts of the system (transducer and a display).

To install it . . .
1. you cut your fuel line (after the fuel water seperator)
2. mount the display in your dash (requires a 2" hole) then snake the wire and transducer from the display in your dash to the section of fuel line that you cut.
3. Put hoses clamps on either side of the transducer.

That's it!! Shouldn't take more than 20 minutes total . . . the hardest part is snaking the transducer from the dash to the stern of the boat.

I'm not exactly sure how the flow is measured, but I suspect that there is some type of rotor inside the transducer that turns as fuel passes through the transducer and a sensor that counts the rotations of the rotor. Based on the times the rotor spins the computer (in the display) calculates the fuel flow.

Navman and Standard Horizon are the same flowmeter. I had a Navman 2100 on my last boat and it worked great . . . very accurate.

I bought the 3100 for my project 23+ and the instructions say you have to run the motor(s) out of a separate tank with a known amount of gas to calabrate the system. There is a turbine that spins to measure the flow. I had several people recommend Navman and the price was better than Floscan.

Thanks guys [img]/images/graemlins/grin.gif[/img]

I think I'm getting a Navman, either the 2100 or 3100. I think its about time I got rid of that crappy bouncing
gas guage.

Tim,
That's just what I needed [img]/images/graemlins/grin.gif[/img]

When you get closer to buying . . .

boater's world sells the 2100 for $149.99 + free shipping!!!

I didn't have to calibrate my gauge . . . It was right on out of the box. Navman gaurantee's within 5% accuracy out of the box, but it's a good idea to calibrate it anyway . . .

I just bought one for around $500. My whole rigging which included new shift cables, wiring harness, 2 digital gauges the fuel management system, binnacle controls, and rigging tubes cost about $1500. Check that price maybe it included installation but it still should have been cheaper than that.
