TrueFlow HVAC Air Flow vs NHCA Repair or Replace Guide

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.
