Fuel Flow Meter?

[facthunter]

The most reliable gauge is a clear bit on the tank. Nev

There is a sensor you can buy pretty cheap Jack that you could put on the outide of your tank..a couple of them for levels to bring a LED on. a small bargraph with 3 or 4 of them for fuel levels..they are ultrasonic so pass through almost any material

Thanks Mark,  I have to fit something as the clear tubing cannot be seen from cockpit, only on the ground.

Will a mirror do it?. Nev

Nev, the clear tube is sandwiched in the middle between the tank and rear cockpit wall, hard enough to to see on ground looking at it.  Would have been far better towards one end of the tank.

Now THAT's tricky.  I might have to look at getting a couple.  Mounted on the side of the tank around halfway.  Somehow you'd have to reverse the electrickery setup so that your two warning lights come on when they no longer sense liquid, rather than go off.

The wires coming out have the outputs..you can get them with the PNP versions there and also NPN...the LED built in is just a indicator of course..with the wire output because it is a switch basically..a electronic switch with a couple of small parts you can make the indication on your panel the way you want

 

There is a whole raft of them and about 20 bucks  so you could put 4 on the outside and have the 4 segments displayed on the dash easily

 

Belite (Radiant Instruments) use them although theirs is quite expensive but is a ready to go solution  He calls it a bingo  as in last fuel so a low level but with more its more levels of course
