HVAC Airflow Meter

This application measure air flow in ventilation equipment. The primary use is balancing a ventilation system, that calculates the air flow with the following equation (Swegon and other brands).

q = k · √ p (l/s)
q = measured air flow (l/s)
p = actual balancing pressure (Pa)
k = k-factor

In order to measure a USB differential pressure sensor in needed. The price for the sensor is 150 EUR + VAT + shipping + customs duty, dispatched from Sweden. To order a sensor send a email to: droidhvacairflowmeter@gmail.com

A possible improvement to this app is to add a balancing protocol to reduce the paper work and speed up the work.
