The all new Digital TrueFlow Air Handler Flow Meter provides a simple and accurate measurement of airflow through residential air handlers. The Digital 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. The TrueFlow Meter provides direct CFM readings in 2 to 3 minutes without extensive calculations or setup. Can be used in a wide range of return plenums and air handler fan configurations. Proven to be more accurate than the single-point temperature rise method and easier than the fan curve method.

The new Digital TrueFlow features a built-in pressure gauge to allow wireless readings without the need to physically attach any tubing to the unit itself. Use your Android or iOS device to wirelessly control the Digital TrueFlow and a TEC digital gauge (model DG-8 or DG-1000) with the upcoming TrueFlow HVAC app and create detailed system reports. With the Digital TrueFlow Solution, it has never been easier to get it right!
