Fuel totalizers for large Cummins

[tractorface]

Hey guys I am running into some difficulty at work and thought someone here may be able to help me. I have a couple of QSK78-G6 diesel engines that I need to equip with Fuel totalizers. Anyway they flow 590 GPH with a max return of 555Gph. The typical Flo-scans that I use give me too much pressure drop so I am looking for a larger system. Any of you diesel heads recommend a good vendor for such a product.

BTW these things are equipped with 6 HX83's burn 172 GPH and make 3740HP and hold 312 qt's of oil. That would make the Amsoil man very happy I bet



Thanks in advance

Can you just get 2 of them, then plumb them in parallel?

tough to do

Funny you asked. I was thinking the same thing. Not sure it is feasable. The system works by measuring the fuel to the injector pump and the fuel returning from the injector pump. The math would get all screwed up if say the flow through the lines was not exactly right. There is an outfit in Seattle that has great product, trouble is they are not real good at responding in a timely fashion. As usual time is against me.

Thanks fo thinking like me though, good to know I am not alone

It may be a pain, but could you use a valve on the higher flowing path, then close the valve 'til the flow is matched thru both? I've never seen or heard of a Fuel Totalizer before.



--edit-- Did some looking on the 'net. From that and what you said, it is used for figuring fuel consumption, right?

Exactly

They are used mainly in Airplanes, boats, and Generator applications to keep track of fuel consumption. In my case it must measure down to tenth's of a gallon burned. Basically it is a form of emissions control. Some regulating body "permits" the amount of fuel a given genset can consume over a certain period of time thus limiting its emissions. I believe in this case a "penalty" fee is paid for fuel used over and above the permitted amount.

Thanks to the wonderful EPA, huh? :-{} On the 'sets that are for stand-by operation only, it seems stupid to me the BS with emissions. If they were run 24/7, 365 I could maybe see that, but for stand-by?
