Air Handler Flow Meter The TrueFlow® Air Handler Flow Meter* is designed to provide a simple and accurate measurement of airflow through residential air handlers. The TrueFlow Meter temporarily replaces the filter in the air handler distribution system during the airflow measurement process. If the filter location is directly adjacent to the air handler, the TrueFlow Meter will measure the total air handler flow. If the filter is located remotely at a central return, the TrueFlow Meter will measure airflow through the central return.
Air Flow Testing We use several techniques to measure air flow in HVAC systems, including flow hoods, velocity meters using a traverse method, and an air handler flow meter. Proper air flow required to ensure the amount of air needed to satisfy the heat load of a given room is delivered to that room. It is also critical to the overall efficiency of an HVAC unit to have the correct amount of air moving across the coil so that the
