Product Description
The Energy Conservatory Digital TrueFlow Solution - Full Kit - TFD-KIT-001
(Grid, DG-8 Digital Gauge (Manometer), 8 Adapters)
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 using a pre-cut or cut-to-fit adapter plate. 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. TrueFlow Air Handler Flow Meter Easy and fast to use in the field. 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 DG-8 with the TrueFlow HVAC app and create detailed system reports. With the Digital TrueFlow Solution, it has never been easier to get it right!

(1) Typical Conditions are a temperature range of 54° to 90° F, and a two year calibration interval.
(2) As Calibrated Accuracy is +/- (0.4% of reading + 0.045 Pa) under controlled conditions of 67° to 77° F, four month calibration interval, and pressure readings averaged for five seconds. All gauges are verified to meet this specification at all calibration pressures.
(3) For use at temperature conditions outside the typical conditions in Note 1, or the as-calibrated range in Note 2, add an additional 0.037% of pressure reading per degree F over the stated range.
(4) Storage limits are based on batteries. Storing outside these limits may require battery replacement.
