HI
They use mechanical gas sniffers in mines all the
time. We have sensors that detect methane oxygen
pecentage and co parts per million.The system is
hooked to a main computer that is also monitored by
human back up. They also use handheld devices that can
monitor any individuals environment.Surely there is
something that could be put together to monitor kilns.

Yes there are propane, etc. detectors, as others have already posted.
I can't help but respond by saying...fix the leaks !!! Seems prudent to =
eliminate the problem instead of having a device to warn of when it's =
happening.

Hello,
I was wondering if there is any kind of device (other than a human nose)
that can detect a propane or natural gas leak (like a CO2 sensor)?
We've been having a bit of difficulty with gas leaks on/around our kiln,
and I was wondering if something like this could be employed, in the off
chance that someone doesn't find it in time.
Thanks,
-scott

Hello Scott,
I suggest you call either RG and E, or else Isaac Heating. I've seen both
of them bring in a multi-meter sensor on a wand and wave it
around...according to the service people, it is incredibly sensitive and
can detect leaks that are not noticeable to the human nose. I don't know
what they're called, just that they have them.

Scott,
I know that there are natural gas sniffers. When I was buying my house
and I was having a mechanical inspection prior to buying it I could
smell a small natural gas leak. The inspector pulled out some fancy
device and sniffed along the gas line by the furnace. She determined
there was a leak in one of the pipe joints and was able to mark the
exact spot of the leak. It made an audible sound, the higher the
concentration of gas got. That being said I don't know if there is a
device that you install like a a CO2 or O2 detector. Have you tried
Googling it yet?

Scott,
Your gas delivery company should have a meter. You can check it
yourself with a small brush and soap suds. Paint the suds around every
joint from the meter to the kiln. Any leaks will produce soap bubbles.

Scott,
Propane snifters are highly recommended on boats. We have one installed at
the lowest level.....on the floor directly by the stove. It is a good safety
feature when hooked to a loud alarm system. Try a marine store such as West
Marine or Boat US (both owned by the same people now)

Then too, one could allways tie a Canary on the end of a
stick...poke around, see what it does...if it wilts, might
want to ckeck it out further with a Kitchen Match or
something...the leak I mean, not the Canary...
Just a thought...
Too, for some reason, many Propane Jugs, or maybe their
regulators, when the Tank is almost empty, will leak, ever
so slightly...

I bought one of these sniffers 1980's vintage . It worked o.k. I still
resorted to soap to find the leaks. I suspect the newer ones are
better. Its dead now.

Dear Phil,
Often wondered about this.
Is it something to do with entraining a greater proportion of
Stenching Agent as the ratio of one to the other changes when the gas
gets low. So, as your turn on the gas there is proportionally more
stench in the gas which gets away just prior to ignition.
If there was a leak along the line the stench would be persistent and
the bottle would empty within a couple of days.
Best regards,
Ivor Lewis.

Ivor and Olive Lewis on fri 14 jan 05
Dear Scott Paulding,
I take it you are speaking of a leak that would not be detectable by
the old paint brush and soap solution method ?
If so, get onto a chemical industrial instrument supplier like Hotek
Technologies

Ivor Lewis.

Dear Edouard,
So do I ! ! Learned to do so when I was firing Hydrogen atmosphere
sintering furnaces. Did not wish to be initiated into the realms of
"Rocket Science" ! !
Frequently when Olive tells me she has detected a whiff I do the test
. Always a negative with the soft soap bubbles.
But her observation correlates with a bottle that is reaching
emptiness. Which is why I put that proposition to Phil in El Ve about
the delay between emission and ignition allowing gas with a higher
stench load to get into the local atmosphere.
Best regards,
Ivor Lewis.

Hi Ivor,
It is a mystery-to-me...
I run my Kitchen Stove on Propane, and have for these many
years here ( 17 or so for the Propane method, was on Natural
Gas lines before, in a different building)...allways useing
those jugs of the five-Gallon way of faith.
And...somewhere along the line there, I noticed that when I
could smell the scent of the gas ambiently in the vicinity
of the Stove-and-tank proper, that is only if standing just
immediatly there next to
them, ( of course, the smell is very slight in these
occasions, ) it heralded the Tank having become almost
empty. The tank, being some ohhhh, four feet or so from the
Stove and under a simple Kitchen Table against the Wall
there, where, also, it has allways been easy just to reach
over to it, and
to tap the tank with say a big Spoon or or one's knuckles or
something, and listen to the sound, especially if one tilt
it at the same time, one can tell it is indeed, about empty.
I imagined it was either the Tank Valve assembly itelf, or,
possibly the Regulator ( which in my case, is fitted
directly to the valve assembly) which somehow would tend to
exhale or sigh a little when the interior pressure were low
enough. I think I have experienced this with Acetylene Tanks
and or their Regulators also...when their interior pressure
is at it's last, or about least...but that is as far as I
ever got in my
(not much of ) investigations ( rather, merely accepting it,
like so much else in life...with gentle or amused and
affectionate tolerance, for vagueries...)
One time, I was doing something here in the office, and I
heard a "Pssssssssssssssssss..." start up, that was going
along pretty good for
itself in an ajacent room. I had that day brought home a few
small sized ( one Gallon) Propane Jugs, full ones, that a
friend gave me who used to use them in his Plumbing
Business, and I thought they might be handy for something or
another. It was Summer, and maybe 102 F inside here or so,
and...anyway, one of the little rascals had popped something
in it's valve assembly, (Valve was closed tight and I
checked it to make sure) and of course the Gas was hissing
out furiously. So I walked over to it and picked it up and
set it outside where it could hiss all it liked...and, then,
out of maybe prudence or something, squinting at the other
ones, I set it's bretherin out there too so thay couls all
keep eachother company.
Never had the ones I use for the Stove do that...could be
kind of interesting if they did I guess, especially if I
were not home...or even if I was!
I never notice any different threshold of the scent of the
Propane in turning on the petcocks for any of the Stove
Burners, which oblige one to light them manually if you want
a
flame...so, as far as there being maybe a higher
concentration of the stenching-agent as one gets to the Tank
being about empty...all I can say is that I never noticed
that in routine use of the Stove, where, usually, I turn the
petcock for whataver burner I intend to use, fumble for my
Zippo or some matches, light it, get a little 'whoosh' as it
igniites, and...at most catch the tiniest whiff of scent,
but never more-so or less-so as relates to how full the jug
is.
This of course, noticing the tell-tale to "empty" scent or
Propane, is with no petcocks having been turned on, andseems
to come somehow, from the Tank or regulator itself only when
the Tank ( any of the Tanks I have owned or used) is about
bone dry empty. In fact, when I do notice the scent, I know
I have enough Gas remaining for maybe two pots of Coffee or
the likes...and then that's that.
Yer pal,
Phil

Hello Ivor,
"my friend Bob who is our regional propane technician uses the soap
solution"
Bob also taught me to use Windex in the case I have no soap solution.
Windex is a glass cleaner containing Ammonia.
Bob besides being a propane technician is also our regional inspector
for the provincial govt.
If he says no, you cannot buy propane so, I believe his technique to
check for propane leaks are adequate.

Thanks Edouard.
I believe, if the Windex you are speaking of is for cleaning windows
and not for curing "Gripe", it will have a detergent action. So it
must contain some agent that will foam as well as de-grease, wet and
clean.
All sorts of ways to get round a problem with a little lateral
thinking but be cautious. Ammonium Hydroxide, even in dilute
solutions, may have a corrosive effect on brass and copper fittings.
Best regards,
Ivor Lewis.
