ABSTRACT:
A networked air measurement system includes a sensor capable to measuring a characteristic of an air sample, the sensor having an air inlet port; a backbone tube in communication with the air inlet port of the sensor; a plurality of air intake valves in communication with the backbone tube, air admitted through one of the plurality of air intake valves communicated into the backbone tube; an air flow induction device in communication with air in the system, air moved by the air flow induction device from the plurality of air intake valves through the backbone tube, to the sensor; and a controller connected to the sensor and to each air intake valve, the controller executing a control sequence which opens and closes air intake valves to admit air and form air samples communicated to the sensor. The system controller may use time intervals or measurements of air samples to determine proper times at which to open individual ones of the air intake valves. Furthermore, the system may include air routers and branches through which air admitted through an air intake valve may be routed to a predetermined destination. The air intake valves may be of an averaging type.
