VOLU-flo/OAM Outside Air Monitor


The VOLU-flo/OAM consists of an Outside Reference Sensor and an Inlet Airflow Sensor, both specially designed to be unaffected by dirt or moisture, plus a temperature sensor and a microprocessor-based Monitor/Controller which converts the measured pressure drop and temperature to actual airflow. The VOLU-flo/OAM has been specifically designed to measure the airflow rate within ±5% of actual airflow by measuring the pressure drop across a fixed inlet resistance device, such as a louver, layer of expanded metal, etc.
