A method of measuring airflow from an HVAC outlet vent using a volume fill airflow measurement device having a LIDAR or Time-of-Flight (ToF) laser-ranging sensor to detect a filled state of a volume capture element or bag, comprising placing a frame having the bag sealably attached thereto over the vent to be measured, starting a timer, stopping the timer automatically in response to the LIDAR or Time-of-Flight (ToF) laser-ranging sensor measuring the distance to be within a predetermined range, and calculating the measured airflow based on the volume of the bag and the time for the airflow to fill the bag. The measured airflow is then displayed on the device display.

Volume fill airflow measurement

A handheld-sized, single-hand-holdable, single-hand-operable battery-powered digital backflow prevention assembly testing gage capable of measuring a differential pressure between high and low side fluid sources, providing a capture value function for easily recording pressure values while continuing display of live pressure measurements, and providing a rate of change graph display for immediate visual indication of changes in the differential pressure being sensed. The design utilizes a true differential pressure sensor for more accurate measurements, provides for use as a 5-valve, 3-valve, or 2-valve tester conforming to standard industry field testing procedures, and permits wireless transmission of measurement and related data as well as remote wireless calibration of the testing device.
