A portable negative pressure wound therapy system includes a dressing assembly for positioning over a wound to apply negative pressure to the wound and a canister assembly. The canister assembly includes a control unit, a vacuum source disposed in the control unit, a pressure sensor in communication with a processor unit of the control unit, and a collection canister. The collection canister includes an inlet conduit in fluid communication with the dressing assembly, a first chamber to collect wound fluids, an inlet port coupled to the inlet conduit to introduce the wound fluids from the dressing assembly into the first chamber, a suction port to communicate with the first chamber and the vacuum source, a pressure sensor port to communicate with the first chamber and the pressure sensor. The pressure sensor port is in fluid communication with a“T”-off point between the inlet conduit and the inlet port.
