Digital TrueFlow® Solution Full Kit
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.
