How to measure External Static Pressure with Tony Gonzalez of Fieldpiece

[@normchristopherson5799]

Excellent, clear, concise and useful presentation on external static measurements. Fieldpiece wireless instruments and Job Link are such an improvement over anything we have had in the past. Now we have simple, fast and accurate measurements compared to what I learned on over 50 years ago when I started in our trade.

Thank you for actually showing a problem and how it might be fixed.

ok i am confused. you said "to point it in the direction of the air flow" its an up flow unit. shouldn't the tip point up? please clarify. thank you.

[@drcoffee5588]

Air flow is going from bottom to top. Point it down into airflow

[@Edmonton98]

@@drcoffee5588 You did say in the direction of the airflow not towards. Confused… 😬

@@drcoffee5588I think you were right the first time. Still confused. Watched this 20 times.

[@murky2502]

@@Edmonton98 Yeah, it probably should say "into" the direction of airflow, meaning opposing the flow of air. "in" the direction of airflow suggests along with the flow of air. I've seen the same thing in other descriptions. The good thing is that it both are fine. The purpose is that the holes are in the sides of the point and you don't want the blowing air aimed into the holes, you want the holes perpendicular to the air flow so you are only getting the ambient pressure, the "balloon" pressure and not catching flowing air.

What is good static pressure for supply and what is good static pressure for return? To confirm where the issue is?

[@drcoffee5588]

My question is, if you open all the damper/vent and achieve 0.50 wc and the furnace is running optimally, but one day granny closes some vents cause she is cold and it ramps up the static pressure to 0.80 wc, wont that damage the blower motor? Is it better to set static pressure at lets say 70% of max to allow for variances? I thought I heard it in another video, but has only come up once that I know of. Thx

Where would you insert the probes if you installed a heat pump air handler, with the system being a horizontal left, the coil being on the right and the blower on the left side?

[@AirJesus]

Your return side probe will go into the return plenum directly before the factory filter rack, and your supply probe goes into the supply plenum directly after the air handler. Make sure that you put your supply side probe in the top of the plenum towards the back side of the air handler so that it is in the airstream. Both probes need to be as close to the air handler as possible with the red arrows facing INTO the airflow (supply probe arrow facing towards the return side of the air handler, return probe facing towards away from the air handler)

@AirJesus thank you so much for replying. Our community is based on positive support for each other and you my friend are a great example.

great video sir...
