dwyer manometer

I just bought a dwyer manometer in order to test gas pressure on a gas valve well to my suprise there is no owners manual with it and tech support is beyond useless can anybody provide a users manual or did i just spend $275.00 on a nifty paper wieght yes i checked there web site sent them nan email and followed it up with a phone call to no avail

Is it the Series 477 Ed?

Mine did not have instructions either beyond the generic how to use a pitot tube pamphlet. I found it pretty straight-forward. Turn it on, zero it and off you go. The catalog may have more information than that. Surprised that you find nothing.

Let me know or contact me off-line if you like.

You should read

"Measurement of Pressure with the Manometer" in our catalog

I got no paperwork with the manometer then when i try looking up literture on thier web site it tells me i need permission to view it why the heck does a company sell a digital instriment and provide no instuction sheet i have the model 475-1 digital manometer only instuctions on use are on the card backing the plastic display package

I know what you mean it just makes no sense to sell something without documentation, they say on the facts page to review info in thier catalog, was you able to load the page I sent, it has the catalogs and a place to submit your name and address

Kevin O. Pulver

I agree

You can't even buy a lousy toaster without a manual to help you enjoy the full potential of the thing.
I shelled out $600 or so for a Rothenberger tee puller, and NOTHING. I'm impressed, but not in the way they hoped. Kevin

Hi Ed


Not sure if this helps, but try this.

Gas Line Pressure

Hi,

I just read your post regarding the Manometer. This instrument is used to test pressure of air within a moving body (ie, ventilation sytems, exhaust stacks, etc.)

I don't think you are using the right tool for your application.

I've got some instructions for the use of a pitot tube and manometer that I could post which will show how to measure the velocity pressure and subsequently find cfms. (need to make them .pdfs) However, as far as wanting to know the pressure in a gas feed line, unless you want to test how quickly the gas is moving, this isn't the right tool. It works amazingly well if you're attempting to understand the volume of air being drafted to the chimney.

Cheers,
Greg

It will measure

any gas within it's pressure range, moving or not. It is a total pressure gauge and that includes velocity, static and total pressures.

Brad White_9

Here is the attachment I sent

last night to you, Ed. On page two are the operating instructions.

Anyone else care to take a look and see if I am missing something? Seems pretty straightforward to me. I would cut and paste the text but it is an Adobe PDF file so you just have to open it and read it. Too lazy to type I suppose.

Nothing to it, just zero the gauge before taking a reading.

Bob Eh?_2

For what you want to do just zero the guage connect the high presure port to the test port on the burner assembly or meter (Adapters often required) and read the pressure....

OK

Greg_34

OK

So, he'll just need an adapter, and not use the pitot tube. When I looked at the equipment on Dwyer's site, I knew using a pitot tube wasn't an option.

thanks for the heads up.

You beat me to it.


I was just about to post that link.

Ed, could you be more specific about what you want to know?

dwyer meter

ok call me a freeking idiot if you want to but those directions are no help at all what do i need to do to hook up to a gas valve it really would be nice if dwyer would include written directions on how to use this manometer heck i have neber ever bought a test meter of any sort that did not have some sort of manual that explains how to use it heck most have drawings that show how to use

Digital manometer

Ed, I hope you didn't buy that fancy digital manometer just to check gas pressures. All that's required is a couple of feet of small diameter hose or tubing an adapter a bucket of water and a ruler. Connect the tubing to the gas, stick the other end in the water, turn on the gas and pull the tube up until it just starts to bubble. Measure how much tube is below the surface of the water and that's the pressure in inches water. Cheap and more accurate than a digital. bob

I am less han fifty miles north of Boston e-mail me I am sure I can get you headed in the right direction. I use a U-tube myself.

HI ED

I have the same meter on my truck. Only thing you need to measure gas pressure iis a chunck of tubing and the barb connector that goes in hte outlet pressure tapping of the valve. Remember to plug the negative pressure port as I believe it can effect the final readings. I especially like the meter to check the negative gas pressures on W/M GV boilers(-.2" WC). It really pegged a couple for me.
The biggest complaint that I have is that it seems extremely tempermental in low teemperatures. IT IS NOT the meter to get of the truck in 0 degree temps and expect to be accurate. Once it warms up, however, it seems to be ok. Also, when the battery gets low, it hunts without warning. I wish the instructions were more accurate also but what do you do. Good Luck. Hope this helps.

Gas pressure Test

I've been using the Dwyer 0-5" and the Dwyer 0-10" magnehelic forever. No batteries, easy to calibrate, checks positive/negative pressures. Along with a Ritchie 0-20 0z guage, you're set-all three for less than one digital.
