Measuring Water Flow Rate at Circuit Balancing Valves

Bob Blanchard of the Ontario Sheet Metal Workers Training Centre guides you through how to measure external flow rates at circuit balancing valves.
This video is part of the TAB Technical Manual Training Course for sheet metal workers who want to develop technical HVAC skills. Produced by the Ontario Sheet Metal Workers Training Centre www.osmwtc.com/

well briefed and illustrated thank you

[@YesthisisCharlie]

Is it safe to permanently mount a flow sensor there ?

[@konsul2006]

Thanks

[@masterchef6694]

what is the instrument you are using to measure the pressure?

[@joemilton7552]

he says at the beginning, hydronic manometer

[@StupidPeasant]

I wish the balancers would mark or label what they set up so years later, some tech has bumped or changed it, we can put it back. I wish they would maker damper positions too. I also wish I had a lot of money.

[@tylermckinley719]

The TA and Armstrong valves both have a memory stop feature. There is a small Allen key you tighten down in the center of the valve head to lock in the balanced position. Once memory stop is tightened up, you will still be able to close the valve all the way but you will not be able to open it passed the balanced position.

[@muhammedarif7560]

can you please let me know the name of instrument and its part number you using to measure in this video

[@joemilton7552]

he says at the beginning, hydronic manometer

[@syedimranrasheed1553]

what instrument in the video and the chart being used? please if u share any video share the full details so that viewers can understand..

[@strikerj4810]

Dude said it all in the video.

WHERE DO I GET THE WHEEL

[@jordanairbalancing]

Contact your local Victaulic dealer.

[@ACHVACTAB1]

Bob, Not sure why you set the meter to bypass and than hook up to ports. Bypass equals the + & - gauge reading, than zero it, Now you ready to connect it and measure DP
You also should note the likely motorized modulating valve that MUST be open before you do the above.

[@OneOfDaLast]

You can zero it after connecting as well.

[@jacklaw9867]

haha, "that's how simple it is!" It should be fairly obvious to anyone who holds an advanced degree in hyperbolic topography!

[@stuartewoldt1513]

This guy shows you how he does it Doesn't really get into the real basics. Can anybody see that wheel

[@MrAerazo]

Stuart if he shows you the basics then he won't have any students in his class
same goes for achvactab1
notice the Title on the video Ontario Sheet Metal Workers Training Centre
and why is a Sheet Metal Workers Professor teaching a closed loop flow rates circuit balancing class to sheet metal workers?
no wander my chilled// Hydronic systems never work properly ( done by Sheet Metal Workers!!//???

[@luisbrenes7039]

sorry about your video I can't see anything

[@barbonusbar82]

Variable orifice valves are becoming a thing of the past and also you should vent 1st before recording your reading

[@DarkSiderSS0]

look at the video date

[@shankarbk7503]

can not understand

[@juliocv719]

1980

[@chinino89]

Pero funciona.
