1. A method of mounting a device to a fixed resistance for sensing an airflow in a duct, the device including a housing mounted to a mounting plate, a first static pressure tube having a first opening as a first outlet connected to the housing and a second opening, a second static pressure tube having a first opening as a second outlet connected to the housing and as second opening, the method comprising:
extending the second opening of the second static pressure tube through the fixed resistance from an upstream side to a downstream side of the fixed resistance;
mounting the mounting plate to the fixed resistance such that the mounting plate extends across the airflow of the duct and the housing and the mounted plate are on the upstream side of the fixed resistance;
connecting the first outlet and the second outlet in communication with a transmitter and/or a controller for communicating pressure readings from the first outlet and the second outlet to the transmitter and/or controller.
