Abstract
An assembly for handling a fluid, comprising a valve and a controller. The valve has at least one revolving valve element and a coupling device. The coupling device comprises at least one port coupled to a flow path and is adapted for interacting with said at least one revolving valve element in order to control a fluid flow through said at least one port using a relative valve position between the revolving valve element and the coupling device. The controller is adapted for controlling the relative valve position based on at least one of a current and a previous measurement of an amount of the fluid flow dependent on the relative valve position.
Claims14
An assembly for handling a fluid, comprising
- a valve having at least one revolving valve element and a coupling device, wherein said coupling device comprises at least one port coupled to a flow path and is adapted for interacting with said at least one revolving valve element in order to control a fluid flow through said at least one port using a relative valve position between the revolving valve element and the coupling device, and the movement between the revolving valve element and the coupling device is a revolving movement, and
- a controller adapted for controlling the relative valve position based on at least one of a current and a previous measurement of an amount of the fluid flow dependent on the relative valve position.
A fluid separation system adapted for separating compounds of a fluid, comprising:
- a fluid provider adapted for providing the fluid,
- a separation unit adapted for separating compounds of the fluid, and
- an assembly comprising:
- a valve having at least one revolving valve element and a coupling device, wherein said coupling device comprises at least one port coupled to a flow path and is adapted for interacting with said at least one revolving valve element in order to control a fluid flow through said at least one port using a relative valve position between the revolving valve element and the coupling device, and the movement between the revolving valve element and the coupling device is a revolving movement, and a controller adapted for controlling the relative valve position based on at least one of a current and a previous measurement of an amount of the fluid flow dependent on the relative valve position.
A flexible test chip comprising:
- assembly for handling a fluid, said assembly comprising:
- a valve having at least one revolving valve element and a coupling device, wherein said coupling device comprises at least one port coupled to a flow path and is adapted for interacting with said at least one revolving valve element in order to control a fluid flow through said at least one port using a relative valve position between the revolving valve element and the coupling device, and the movement between the revolving valve element and the coupling device is a revolving movement, and a controller adapted for controlling the relative valve position based on at least one of a current and a previous measurement of an amount of the fluid flow dependent on the relative valve position,
- wherein the test chip is adapted for diagnosing a revolving valve element adapted for controlling at least one port of a coupling device.
A method for handling a fluid in an assembly comprising a valve having at least one revolving valve element and a coupling device, wherein said coupling device comprises at least one port coupled to a flow path and is adapted for interacting with said at least one revolving valve element in order to control a fluid flow through said at least one port using a relative valve position between the revolving valve element and the coupling device, and the movement between the revolving valve element and the coupling device is a revolving movement, the method comprising:
- controlling the relative valve position based on at least one of a current and a previous measurement of an amount of the fluid flow dependent on the relative valve position.
