Patent ID: 8475715

Claim:
A method of reducing interference from gas in a resonant sensor system, the method comprising: (1) providing a resonant sensor system comprising: (a) a fluid chamber defined by a plurality of interior surfaces; (b) a resonant sensor device defining at least one interior surface of said fluid chamber or disposed within said fluid chamber; (c) at least one inlet port and at least one outlet port in fluid communication with said fluid chamber; (d) an inlet valve adapted to selectively allow a fluid flow through the at least one inlet port; and (e) a pump disposed downstream of the fluid chamber in fluid communication with the at least one outlet port, the pump adapted to pump a fluid through the fluid chamber; (2) opening the inlet valve and permitting the fluid to flow through the fluid chamber using the pump; closing the inlet valve while continuing to use the pump to generate a decrease in fluid pressure within the fluid chamber; and re-opening the inlet valve while continuing to use the pump to permit the fluid to resume flowing through the fluid chamber and to increase fluid pressure within the fluid chamber, the re-opening the inlet valve and the increase in fluid flow and fluid pressure within the fluid chamber reducing interference from gas in the fluid by at least one of: (i) dislodging bubbles from the fluid chamber or (ii) reducing unwetted surface of the resonant sensor device.
