Fuel Flow Sensors

Hi Team,

Hoping for a bit of advice and get some other peoples experiences. I am currently running a HDS9 gen3 as a plotter and some engine managment functions.  I have the EP-60r fuel flow sensor hooked up to this through the nmea network.  This works really well at measuring the fuel used, generally after a couple of hundred litres used I am about 5l out from where it says it should be.  However, I am now on my third sensor. The first one i got second hand and it died quickly, fair enough I thought, thats what you get, the second one I got new and it lasted just under a year before it died and I got it replaced under warranty, now the third one has lasted just over a year and has recently died.  

Has anyone else had similar experiences with these?  Any suggestions on what is going wrong?

And seperately, does anyone have a fuel flow sensor hooked up to a Furuno GP1971f?  And if so what flow sensor did you use?

thanks

What fuel.. ?

diesel or petol ?

When you say it dies, does it just stop giving info or does it leak? Does it restrict the fuel flow ?

None of this is really going to help you... but I am interested in your predicament.

Ihave had a EP60 for some years without any obvious problem, but I have a small 90l tank (petrol)and also an accurate fuel sender so I dont pay a lot of attention to the ep60 data.

 "just over a year" doesn't really cut it, you need to approach the business that sold it for a replacement as its reasonable at the price to expect it to last longer than a year.

The warranty they "give" you has no bearing on that.

Thanks guys,

Its a petrol, when I say it dies it isn't recognised on the nmea network, its not a network issue as I can still see other things on the network, just not the fuel flow sensor.

 

Yep, I agree Rob, I will be trying the warranty, but first, is it something I am doing or just the system? I find it hard to believe its me, its a very simple plug and play set up.

That was my experience too. I used to have an Navman inline petrol sensor. They never lasted more than a couple of years and were'nt cheap to replace.

I repowered with a Suzuki outboard and fuel flow is inbuilt, I think it gets its data from the fuel injector sysytem somehow.

Underreads a bit but consistent and good enough to be useful
