How many have a fuel flow sensor?

[Norris_Boating]

Both R7's that I've owned have Fuel Flow readout on the glass. I'm assuming it is actually a calculated flow from injector pulse-width time as I don't see a fuel flow sensor on the network. (deep in the Garmin settings)

Weird that yours isn't working..... I don't agree with your dealer.

I have a 2019 R7 my brother has a 2018 R5 neither of us have working fuel flow info, just fuel gauge. Neither is that accurate (off by about 5%-10%) but it isn't that bad that it bothers us either.
I assume the fuel flow gives you readings like miles per gallon, distance to empty etc. There are a lot of options in the garmin that don't have readings, IE Air temp. These all appear to be $100+ sensors that would need to be added. My dealer too said these don't come from the mfg. tbully, I wonder if since you upgraded your engine to the 430 is why you have it and I don't....humm

I realize that this is an older thread. I just ordered a new 2020 R7 surf... we have about 12 hours on her now. Was out today and noticed the Gal per hour at Zero when under way. Anyone have any more info on this. Thanks in advance for your time.

Here is a link to the trip computer, which essentially is the glass cockpit that you have.

This line from the website pretty much sums it up:
"AVAILABLE DATA
The system is extremely flexible and functions depend on what sensors are chosen. The data available is instant fuel rate, trip time, trip fuel, average fuel rate, and time to empty. With extra sensor or NMEA interface, instant fuel economy, trip distance, average fuel economy, and distance to empty is also available."

Basically Cobalt doesn't buy these extra sensors, you would have to add them aftermarket. Any volvo dealer should be able to install them for you.
