170 and California Title 24 requirements for verifying the required ventilation rates or air changes per hour. The OAFE-2000 is designed to tackle the challenges of outside airflow measurement which is often low velocity, loaded with particulate, and application specific. The packaged system consists of an integral transmitter and multiple airflow elements, factory mounted and pre-piped in a casing designed for flanged connection to ductwork, control dampers, louvers, etc. -

OAFE-2000 IO&M Manual This signal is scaled and linearized before being displayed and transmitted out as a 4-20mA or 0- 10VDC signal. The AutoZero option detects and corrects any zero offset caused by large ambient temperature changes. The Temperature Compensation option compensates the flow and velocity signal for density changes caused by variations in the process air temperature. -
