A method is provided for measuring different flow properties of a fluid. The method includes (a) providing a nanowire, the resistance of the nanowire varying based on temperature changes of the nanowire that reflect values of the different flow properties of the fluid when the nanowire is operated in different modes of operation respectively, such that the nanowire measures different flow properties when operated in different modes of operation respectively, and (b) alternating the nanowire between different modes of operation, measuring different flow properties of the fluid during the different modes of operation, respectively, and using the measurements of one of the flow properties to correct the measurements of another flow property. Other applications are also described.

Embodiments of the invention provide a coupler for use in a closed transfer system configured to selectively engage a container seated in fluid communication with the coupler. The coupler has a body with a slot having an axial component, and an outlet. A probe extends from a first end portion to a second end portion and is at least partially received within the body, the probe is configured to be movable relative to the body between a first position and a second position to selectively control a flow of fluid through the outlet. A probe tip with a cylindrical bore is configured to engage the second end portion of the probe, and a handle is coupled to the probe and configured to interface with the slot. Axial movement of the handle along the slot moves the probe between the first position and the second position.

A system is provided for marketing bedding. The system includes an apparatus for measuring air flow through an article of bedding having a body defining a chamber and an opening that is in communication with the chamber, an air flow generator positioned within the chamber. The system is used to measure the air flow through an article of bedding that covers the opening such that air flow created by the air flow generator passes through the article of bedding. Methods of use are provided.

A substrate processing system includes a gas supply unit having a first gas flow channel. A second gas flow channel of a flow rate measurement system is connected to the first gas flow channel. The flow rate measurement system further includes a third gas flow channel connected to the second gas flow channel, and a pressure sensor and a temperature sensor that measure a pressure and a temperature, respectively, in the third gas flow channel. In a method, a flow rate of a gas output from a flow rate controller of the gas supply unit is calculated using a build-up method. The flow rate of a gas is calculated without using the total volume of the first gas flow channel and the second gas flow channel and temperatures in the first gas flow channel and the second gas flow channel.
