The 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 using a pre-cut or cut-to-fit adapter plate (sold separately). If the filter location is directly adjacent to the air handler, the Digital TrueFlow Meter will measure the total air handler flow. If the filter is located remotely at a central return, the Digital TrueFlow Meter will measure airflow through the central return. The Digital TrueFlow Meter provides direct CFM readings in 2 to 3 minutes without extensive calculations or setup and can be used in a wide range of return plenums and air handler fan configurations. It is proven to be more accurate than the single-point temperature rise method and easier than the fan curve method.

The Digital TrueFlow features a built-in pressure gauge for 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 DG-8 digital gauge with the TureFlow HVAC app and create detailed system reports. With the Digital TrueFlow Solution, it has never been easier to get it right!
