TEC - Model TrueFlow DG-8 -Digital Grid Kit with Gauge

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 TrueFlow® HVAC app and create detailed system reports. With the Digital TrueFlow® Solution, it has never been easier to get it right!
