Gas meter for boiler

Wayco Wayne_2

anyone know where I could get an individual gas meter for a propanr boiler. We need to know how much propane is being used by the boiler specifically. Thanks for any input. WW

We had a similiar situation and were able to order one through one of the propane suppliers. You might check around and see if one in your area can get one.

Got 2 of the AC 250 in Nov. to measure the savings on an Ultra propane installation. Work great!

Credit card and the internet and you can buy most anything!!!

This is the meter I use on monitoring my home system. It can be equiped with a pulse output that can be used with a data logger to show consumption as it relates to real time.

Try


FW Webb/ Victor Supply. Or try one of your local Propane Supliers. Sometimes they have used or rebuilt meters that you can get cheap. If its just for a short time, see if they will loan one to you.

ouch

isn't that about a month's heat on an avg ultra install?

ps what is the diff fom a nat gas meter?, i thought gas meters were of the positive displacement type, and a cubic ft, is a cubic ft, no matter weather it's 4 inches or 15 lbs - i thought just the heat per ft, and the cost per ft, is different, but cubic ft displacement is the same, or does the meter somehow act differently under propane's pressure?

Most meters unless

set up to do differently measure at under 14" W.C.. There are different meters for natural gas and propane. Propane meters can be set up to measure in cubic feet. There are meters specially setup for 2 lbs or 5 lbs. It has to do with accuracy of measurement relative to pressure. They are positive displacement but pressure can affect accuracy as can high flow.

Many large Rotary meters used on commercial systems in fact need correctors placed on the meters.

It is important to let the meter companies know exactly what you want to do with the meter so they can set it up for you.

you mean

compressibility of the gas? that must be it, because i actually took a discarded one apart a long time ago, and it basically had two bellows and a shuttle valve on top, just like a steam engine, as each bellows would fill up - it drove the shuttle valve to close this side and open the other side and the shuttle valve also drove the meter,

so it must be that nat gas bellows are tensioned not to compress inches of pressure, whereas propane bellows are tensioned for lbs – it the only thing I can think of,
however I don’t recall any temperature compensating device, thus when the gas is cold and denser, there is more gas in the same space, so it’s reading lower that actual, – maybe that’s their excuses for charging us more in the winter – yeah,, like they need an excuse

Make sure the meter you buy is TC ed or temp. compensated, almost all are. The meter senses input temp and corrects to 60 degrees. If you are measureing the 11" propane line the nat. gas meter will work fine. If outside the propane version is rated at the higher pressure. I don't know if they pressure compensate, I know nat. meters need no compensation for pressure at 1/2 pound or less, 2 pound gas for instance the input is multiplied by 1.12 to get actual total CF. And meters measure cubic feet or portions of on the test dial. The cubic feet is converted to btu input depending on the gas, LP usually 2500, nat usually 1000.
