Title: pdf on measuring natural gas usage with flowmeters

was looking for information ahead of a possible experiment with NG fog in a diesel intake

found this worth reading

Those gas flowmeters are quite expensive.   I would suggest you do an initial test using your house gas meter to get an rough idea of how much natural gas you are fogging into your engine. My setup is using aprox .5 cubic feet per minute or about 30 cubic feet per hour.  Here is a link to a very inexpensive rotameter that will do want you need.

There's a lot to be said for simple solutions.

A flow meter connected to a controller with a piezo valve to electronically control the flow is an interesting way to do a flood type system. The controller could be programmed with a non-linear flow controlled by a pot on the governor shaft. Doing it electronically would allow a quick change back to straight diesel and allow varying programs for LP vs. Nat gas.

I used a $50 water flowmeter/needle valve from Grainger, for my slow sand filter, and they had a bunch of gas rated ones in their catalog.

Is that on the crankcase drain on your slow speed Listeroid?  ;D

HA !  no, I have a slow sand water filter (updated message above)  and use the flow gauge for that. Just upped it to 2 GPH, now with more people using it.

Never thought of using the listeroid crankcase as a sand filter !

that is the funniest thing i have seen all day!

i missed the first comment about a slow sand filter, then when Tom
responded i picked up on it and just assumed it was your sarcastic remark about
your listeroid as being a "slow speed sand filter"

now i get to reverse my take again!

too damn funny.
