Using a Pitot tube to balance a typical residential HRV install is like making sausages; you don’t want to know what kind of assumptions went in to making that number and yes, as discussed in our previous blog, we at BGG are trying our best to produce more robust numbers than what this simple device invented in 1732 by Henri Pitot.
When in the field, sometimes life throws you lemons and all you can produce is sausage! As unpleasant as using a Pitot tube in a confined space can be, I made a pleasant discovery the other day when I stumbled across Dwyer ‘s Android App (click on link below). This simple app with no baggage (and it’s free) takes the tediousness out of converting pressure in a multi-step calculation to determine air flow through a given diameter duct.
Thank you Dwyer!
