I think all of the ratings that are advertised in mass quantities would be at a standard pressure and density. In the field the density would be subject to change with temperature and specific fuel blend. The 1 or 2 percent variation in density that has previously been dicussed in this thread would ...

but why ?

I'm not too sure about the specifics (this is why I'm asking), but I always thought that the only way to accurately meter mass is through a fixed orifice given a known pressure.

Didn't NASA do the same thing for one of their probes ? For a known pressure through a sintered element that ...

Aren't injectors mass metering devices ? if they were volumetric metering devices, I could see how temp has an effect.

so no matter it's temperature, x mass of fuel is ejected for y amount of time ?

if this is wrong, can you please explain why ?

The Kawasaki Concours (ZG1000) has two VR sensors for the crank pickup. They've been in production since the mid 80's, there are plenty out there.
