Abstract
Methods and systems to measure a volumetric fluid flow rate through a fluid flow passage, such as an air handler of a HVAC system, are described. The system includes an air intake conduit. The air intake conduit includes a partition, an airflow measuring passage through the partition, and an airflow flow-through passage. The partition and the airflow flow-through passage are arranged in a side-by-side fashion. The airflow measuring passage is equipped with an airflow measuring device to measure the air pressure drop in the airflow measuring passage and has a minimal air pressure drop requirement. The air intake conduit has a minimal volumetric air intake requirement. When the air intake conduit has the minimal volumetric air intake, the air pressure drop measured at the airflow measuring passage is at the minimal air pressure drop requirement.
