Tank Inerting

just happy that you agreed on something here - otherwise I would have to throw in my 600 pages thermodynamics textbook from physical chemistry class - and that does hurt :rolleyes:

I’m pretty sure normal fuel level sensors are capacitance type. Like http://www.ametekaerodefense.com/products/sku.cfm?ProductCAtegory_Id=4180&Product_Id=780&SKU_Id=885 Or http://www.gillsensors.com/content/fuel_level_sensors.htm
I flew RC a/c with an old Lockheed RF engineer. He was tasked to develop an oil level sensor for the C-130 engines. At the time they used float sensor that balance up and down. Too much probe build up for electric. He used ultrasound and his paten was for putting the transducer in the bottom of the tank, shooting the ultrasound upwards and tuning it to bounce off the surface tension. After he was done with it, he said Lockheed was trying to use it for fuel tanks.

Does anyone know if it’s possible to inert this thread?

Lol, some people ignore experience because what they read on the net. Sometimes the people with experience are wrong and sometimes the sources on the net are wrong. I wouldn’t argue to much with someone that worked on the jet for 10+ years and I looked on the net….just my .02 about it.

You are confusing fuel QUANTITY with fuel level sensing. Yes the quantity system is capacitance based. No the fuel level sensing system in the F-16 is not. The fuel level sensing system in the F-16 is only in the two reservoirs and it is only for maintaining the fuel level in those two tanks. It is a thermistor that changes resistance based on temperature. That temperature is dependent on whether or not the thermistors are covered in fuel or not.

Yes, yes I am. So there’s a fuel quantity sensor and a fuel presence sensor?
Cali, is the inerting done with any regularity (with and without Halon)?

Yes, but you need to capture the fart of a Unicorn, which is Negative Energy…also needed for warp drives! :uham:

LOL. Dear God guys. I think we stop talking about Tank inerting 3 pages ago. So funny.
Cali, did you guys worked on the inerting system or was it electricians? I can’t remember any more. I know we change the halon bottle, but I don’t remember ever having any problems with the system, so I can remember who worked on it.Additionally, are there differences with tanks inerting pressure and air refueling pressure of the tanks?

I never worked on it, the only thnig we ever did was cap the line on top of the right wing as part of one of our checks. I don’t ever recall hearing about any problems with the system either, can’t say that about other systems.
@Frederf, not sure how regularly it was used.

There are many fuel quantity sensors in the aircraft to tell the pilot how much fuel he has. The totalizer shows the balance of all that electronic wizardry. The fuel level sensing system doesn’t do anything with the quantity. There are only two fuel level sensors (one per reservoir) so it is very much a binary system. On or off. It just manages the fuel levels in the two reservoir tanks.
Matter of fact the fuel level sensors (as well as the fuel level low warning thermistors) are mounted to the fuel quantity sensors in the reservoirs. Just to add back to the confusion.
