disagree..

I have many 4 jet/14" that work fine.... It's all in the placement and flow

And yet probably one of the best wands of all time is a 6 jet 13.5" wand Prochem ti. Which of the many are you talking about? How many 14" wands are there that are relevant?

Dan;
As a user of several flowmeters, I did question the pressure drop spec and pressure deratings.

However, when I checked it against my more accurate sapphire-bearing 0-20ma industrial flowmeter, I found good accuracy and minimal effect of pressure drop.

My new model will also be calibrated before I do any further testing.

Thanks for your concern.
Do you have a hyperlink and/or model number for this more accurate meter? Do you know what the approximate cost is for one of these meters if I were wanting to buy one for myself?

Mark, Did you use this type :
flowmeter-jpg.12425


If so, the only issue we had in several days of testing, is debris getting into the flowmeter. Long yarns or particles ~ 1/8" can lodge between the moving parts and stop the movement, since it is made for air only.

That is what we had I believe.

It was that brand but I don't know where it came from.

We tried it and right away were not really getting an real significant response with it that was making any sense.

It was my first and only time using it, and the place was so busy (outdoor exhibit) we just moved on.

We did spend some time trying to figure it out but I cannot remember much more about it. That was 3 years ago I believe now in Atlanta.

Not sure how accurate it will be but it should tell us how each wand compares..

not so much
gEEk gadgets are cool an'all

but the only right/definitive way is measure how much water went out, and how much was recovered with same TM, same operator with same technique

Rarely ever do we see that
just anecdotal and/or numbers from gadgets not engineered/designed for our application

measure out/measure in....it ain't rocket skiiance

Lots of room for error there Larry. If one person dances thru 500sf in 1 hour, and 2nd person spends 2 hours, it only stands to reason the more time spent on dry vacuuming after extraction would recover more H2O.

No disagreement Rob
but would suggest it's "variables" , not so much "error"

same TM, same operator and their technique may get different recovery rates to another's technique
But would still tell the tale if one wand genuinely recovers better than another

anyone know if CRI did any in/out solution recovery measurements with different wands when doing their radioactive dirt spectrometer "bonze, silver, gold" squeal of approval ?

Ya Larry they did!

And the pc quad won barely beating out the inferior greenhorn, next was the lowly pc Ti!

And lastly the aw29!

They’re testing measures a standard of kick assery developed by real men who like to swing it!

Stating something about Glides are for pussy’s as I recall!

And a real man would also use a platinum standard rug doctor!

Before a wussified gold standard truckmount!

So yes all testing was put to the wussy test!

If it’s harder it’s better!

Suck it it up buttercup.

A better way to measure the "resistance" of a wand, or its flow, would be to blow air through it and measure back pressure.

That doesn't take into account the "airflow thru the carpet fiber".

In our testing we put 10 lbs of weight on the wand head to simulate slight down pressure,

and then pulled the wand horizontally only, on the same type of carpet.

BS Larry.

Measure the WAND. Exclude other variables.

I think Bristor and Larry should hold a public debate on youtube speaking on CFM. Pig farmer could moderate and keep a fight from breaking out. That would be awesome.


Larry’s way to nice! Joe would melt down the second Larry said he liked Joe!

Saying your a MB suck up and a sell out!

Not for the honest guy like me!

Then Joe would sell a cfm tester to a guy. Who would then try to make a few videos!

Joe would call the guy a F...ing idiot for not using the cone of cfm with the proper metal piece attached!

Saying something cute like I made a video on how to do it! didn’t you watch it!

I just bought the tester from you a few months ago Joe you didn’t say I needed any of that!

Ya well this is how we do it now stupid!

I think Joe keeps his customer base under constant PTSD alert!

Sad thing is he has the A day in the life of Wanders YouTube videos!

He sounds normal!

Like I could buy from this guy!

Most have one or two views!

So I post a couple on Facebook!

And boom 80 plus views in under a week!

I say Joe go on Facebook in the groups post the youtube link! Its easy.

He says Ashley banned him!

And Waldo says he doesn’t do Facebook!

I think Joe doesn’t want to read any bad press because it make him mad!

He needs to take a page from thick skin Larry and not sweat the small stuff.

I rigged up a box to test airflow on wands,
I also rigged up a way to test wands when on the carpet, with two funnels and the air meter place inside. I have come to the conclusion that my results are better just kept to myself, because all of the rocket scientists / NASA engineers / backyard briquette masters all some how quite their jobs and became carpet cleaners with massive knowledge

They should just test water recovery because thats all that matters in the end.

Just spray a carpet with water even fan spray, exact same hose and wand do 1 single dry back stroke with each like 5ft long @150ft at the same speed and see how much water is recovered with different blowers

the digital CFM meters I always thought were kind of a bad test, that tube one looks better for sure

BS Larry.

Measure the WAND. Exclude other variables.

By far, the greatest restriction is where the carpet meets the wand lips.

Radius of the lips or glide around the intake will have a significant effect.

Also, airflow will NOT be the same in both directions in most wands.

P.S. According to TConway testing, the Evolution had the best open airflow over the DevPro. Not a wand chosen by discerning buyers.

So what exactly are you looking for in all these tests? Is there an overlying hypothesis that the cfm data will prove or disprove?

I’ll say this everyone whose owned a Big blower and a Prochem Ti would never run a Ti without a glide!

Why??????

Lock down!

Second there’s two or three dudes right now not Cleaning on Facebook threads because of one thing?????

Carpal tunnel!

John Burdick

And Scott Smith

Why????

To much lift and lock down or over working?

I was impressed with how a holed glide and feather touch helped me!

Thank you

Lisa at green glides.

This idea that more bite and a harder to push wand will put us all in the same boat as our friends who required surgery!

Ps

Holed glide on my devastor for the win!
