TEC Digital TrueFlow® Solution Standard Kit with Grid, DG-1000, and 8 Adapters TFD-KIT-005

Digital TrueFlow® Solution Standard 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. 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!
