T&T: Fuel flow meter

[Mike. Maurice]

This might work with a Lehman that returns little fuel. The specific
gravity calibration will not be exactly that of diesel, but it should be
close enough. It is a McMaster Part. THe price is $150. If it were to 
fail and shut off the fuel the engine would die. I don't know what the 
possible failure modes are of this part.
The scale for this part is: 1.2 to 12 gallons per hour. It is the 
smallest unit that I am aware that THEY carry. I have thought for some 
years that this might be an excellent solution for engines that return 
very little fuel.


> The SG of diesel fuel oil (20 to 60) at 15 degress Celsius is 820 to
> 950 kg/m3. In other words, it has from 82 to 95 percent the density
> of water.
