The BGI deltaCal is an EPA FRM compatible flow audit device, based on the air flow measurement
principle of the venturi1. It was developed by BGI and is manufactured in BGI’s ISO 9001-2000
facility. It provides a LCD indication of volumetric flow rate, barometric pressure, ambient
temperature and a filter temperature probe. It operates on either four AA alkaline energy cells
(batteries) or a (provided) line (mains) power module. The electronics are all housed in the control
module.
