N02 Level indicator? I'm new to N02 just got my car back yesterday with the NX system installed. I made 5 1/8th mile passes last night. My question is how can you determine how much N02 is left in the tank or when you need to have the bottle filled? TIA,
Mark
Best N02 pass 7.366@92.70 MPH with a 1.591 60ft.

Re: N02 Level indicator? 383LQ4SS,
The Lp gas tank for the heater on my hot tub/pool has a gauge on it which displays the amount of gas remaining in the tank in percentage. I'm wondering why a simular gauge couldn't be plumbed in with a "T" fitting to the N02 bottle where the tank pressure gauge is. One side reads pressure and the other side reads quantity in percent. Any suggestions or comments?

Re: N02 Level indicator? are you sure your hot tub set up doesn't just weigh the bottle also? as far as i know there is no way to check the level with just a fiting on one of the lines, i float in the bottle might work as long as the bottle is in an upright position and the nitrous is in a liquid form but that would be a huge pain to design.
something that you could make would be a scale that constantly weighs the bottle, but this seems like it would be a pain also. i always just used a fish scale. only took a minute to hook the bottle and see what it weighed, cheap and acurate enuff, i could tell if i had enuff nitrous for another run or not.

Re: N02 Level indicator? Parish8,
The gauge doesn't weigh anything, weight of the tank is irrelevant. The gauge is marked in 10% increments from 10% to 100%, it's a 120 gallon tank, by texas law you can only fill these tanks to 80% full. 80% of 120 gals is 96 gals. So when the tank is full(96 gals)the gauge reads 100%, you can do the math from there. The mass of the gass in the tank remains constant as long as you aren't spraying at the time you take the readings. Maybe I'm missing something here but I don't see why the same type gauge wouldn't work for the N02 tanks.

Re: N02 Level indicator? My wife is an aerospace engineer with a masters in computer science currently teaching computer science at a local university. We figured out how to do it and looked at the programming to do it.
cant dr65 is correct, it can be done by measuring flow from the bottle, the trick is taking gas temperature and pressure into consideration at any given time which also can be done. Once again cantdr65 is correct on pricing, the average F body owner probably wouldn't be willing to pay the several hundred dollars this unit would cost when you can weigh the bottle for nothing. Oh well, It was just a thought.

Re: N02 Level indicator? Mark, no offense but, if you think you got it figured out. Then why not make a proto, work out the bugs and seek backing for production- if you think it'll cost too much, look at the things we buy in our daily life, and BTW the average Fbody owner is only a very small part of the N2O users pool. Hell, I bet you'd get backing if you prove it's worth, with enough support and computer technology you can get the price at a livable level. Look at NX- $200 bottle opener=1)the stereotype Americans are LAZY, 2) proof that if you make it and it works, we who love performance will buy it (as soon as we know it works we automatically find ways to justify our need of it <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> ). Good-luck, and let me know if you are interested I'll put my $$$ in for R&D, might stumble into nice investment.

Re: N02 Level indicator? The only way to measure the amount left in a N2O bottle would be to measure the weight or to measure the amount of N2O leaving the bottle. A float would not be accurate as the amount of liquid varies with the temp and pressure. PV=nRT A mass flow transmitter or turbinemeter would be able to rrecord the amount of N2O flowed from the bottle, though it would be MUCHO expensive and would not be practical. Just take it out and weigh it.... <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Re: N02 Level indicator? Elite, there must be a float in that tank. another method that some computer guru could probably figure out is have it calculated, you would need some type of monitor that looked at presure and the amount of time the soloniod is open, then punch in jet size, it would be able to calculate how much was left.
seems like one of the manufactures could make that work. and as long as it knew what the presure was anytime the solonoid was open it should be prety acurate.

Re: N02 Level indicator? Charlie,
You have made several good points, TEHE I'm one of those lazy Americans with a $200.00 remote bottle opener and the reason for the level indicator is because I don't want to have to pull the bottle out to weigh it. I probably wouldn't require financial backing as I'm older(44)than the average F body owner and have a fairly decent dual income. The set up would go something like this, we would have to use an inline volumn-metric flow meter( very costly) to determine the amount of N02 use, the flow meter would then send an electronic signal to the computer box located in the cockpit which inturn would then display a digital representation of the remaining gas in the tank using the computer program to determine the difference between a full tank(a given)and current level. We already have the basic programing figured out(wifes a brainiac) so I think the next step is to do a cost analysis on the flow meter and the computer box. I'm getting ready to invest some money in another business soon so I'm not sure about the timing, I may have to put it off for a while, but it looks like it might work.

Re: N02 Level indicator? Mark, sounds good, keep us informed of any progress will ya. I like the idea, as I too am looking at getting the bottle opener and all sorts of little gadgets. Anyway, best of luck and post some updates...
