What else might cause false alarms with an airflow meter?
As previously stated, since it is measuring airflow especially in a hospital environment many uncontrollable factors will influence the readings. Elevators on a floor sometimes cause a vacuum as the doors close and they ascend or descend causing a vacuum in the corridor. Laundry carts passing the probe head create an uncontrolled air movement affecting the air flow direction. These are just two examples of actual occurrences that were recorded by users of air flow monitors. In either case the pressure in the room would not have been affected by monitoring with and ACCUSTAT™.
