fuel monitor

How do the fuel monitors work---Navman, Floscan, etc.??



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 . . .

Tim,
That seems like a pretty good deal! Thanks for the info.

Strick,
I've got a Mercury, the way those prices sound I don't think I could afford another Yamaha(except my bike).

Pat.. I have the 2100 on my boat. It works great and was easy to install. Spot-on right out of the box, no need to adjust it . It's allways within 1/2 gallon every time I fuel up.

Don,
I remembered you had one the other day, I'll have to check it out Sunday, it sounds like the way to go.
It's almost quitting time and I can't wait to saddle up.
Take Care,
Pat
