Gas regulator

The reason I adjusted the reg was because Fridge in van not getting below 10 degrees on gas good on 240 and had been getting worse over a period of time. Therefore problem with gas supply
checked at regulator only getting 7.75 inches . found adjuster loose in the reg and it had wound out hence the 7.75 reading. Maker of fridge recommends 11.5 inches adjusted the reg back up to 11.5 inches Bingo fridge working as it should.

I was wondering if gas flow is proportional to pressure

ie higher pressure more gas flow bigger flame more cooling

"Pohms" actually Bantam. (Pneumatic Ohms)

I 'coined' it years ago for calculations related to pneumatic process control instrumentation.
Does not apply quite as accurately as electrical Ohms due to compressibility and other factors peculiar to the fluid, but did have its uses. (We did use more elaborate formulae for serious fluid flow calculations).

Then there are "PneuMhos" which is the pneumatic form of conductivity.

" its basic Ohms law. or whatever they call it in gas."

As an electronics engineer I love that :)

Sorry Greenant, my answer may have confused.

The regulator does not "control" the flow, only the pressure, but as Bantam said, if you make a change to the applied pressure the flow of gas through an appliance will change proportionally.

If the supply pressure is held at a constant value then the flow through an appliance can be varied by adjusting the appliance's flow control, e.g. the hand valve on a stove.

Your re-setting the regulator to the specified value is good. Setting it to higher values can produce possibly serious problems with the burner of the appliance.

If you increase the pressure, the flow will not increase linearly as a result. To double the flow, you need to increase the pressure 4 times - it is a squared relationship. This is academic anyway - you will get more gas flowing if you increase the pressure - just not porportionally more.

hi
as a tech ,there will be a ..## flow pressure chart available for the reg ## .. I do understand the relationship may not be linear
There will /maybe many physical attributes that restrict the reg from achieving perfect performance .
Basically we are talking about the same thing from different ends .
