摘要： The present invention relates to a method of operating a fluidic system, wherein the fluidic system comprises a fluidic resistive element, wherein the method comprises a defined volume flow step, wherein in the defined volume flow step, a defined volume of a fluid is forced to flow out of the fluidic resistive element, wherein the defined volume is the fluid flowing out of the fluidic resistive element in a first time interval defined by a time tstart and a time tend, wherein the defined volume flow step comprises: at the time tstart, switching the system from a first operating state to a second operating state, to bring a pressure in the fluidic resistive element from a first pressure value to a second pressure value, the second pressure value exceeding the first pressure value, and at a time treduce, which is after the time tstart and not later than the time tend, switching the system to a third operating state to bring the pressure in the fluidic resistive element to a third pressure value, the third pressure value being below the second pressure value. The present invention also relates to a corresponding system and a corresponding computer program product.

摘要： A method for measuring a flow of a fluid in a tube includes heating the fluid in the tube with a heating element. A first signal is measured with a first temperature sensing element at a first location. A second signal is measured with a second temperature sensing element at a second location. At least one temperature signal is calculated based on the first signal and the second signal. The at least one temperature signal includes a difference temperature signal and a sum temperature signal. The difference temperature signal is calculated based on a difference between the second signal and the first signal. The sum temperature signal is calculated based on a sum of the second signal and the first signal. The flow is derived based on the difference temperature signal, the sum temperature signal, or a combination thereof.

摘要： A plug unit for connecting capillary tubes includes a plug housing that has an axial borehole, a plug capillary tube that projects through the axial borehole, and a sealing element that surrounds the plug capillary tube. The front end of the plug capillary tube is sealed by an elastic and/or plastic deformation of the sealing element against the capillary tube receptacle opening of a bushing unit. A hollow cylindrical pressure piece is provided that surrounds the sealing element in an axial region facing away from the end surface of the plug capillary tube, and the pressure piece has a rearward end side that faces away from the end surface of the plug capillary tube and that can be loaded by the plug housing with an axial pressure force when the plug unit and bushing unit are connected.

摘要： A switching valve is described that has a stator which is arranged in a housing and which has multiple connection ports. The switching valve also has a rotatable rotor which is arranged in the housing and which, in predetermined switching positions defined by associated angular positions, interacts with the stator for the fluidic connection or separation of predetermined connection ports. The rotor is rotatably mounted, and acted on with a predefined pressing force in the direction of the stator, by means of a bearing and pressing device arranged in the housing. The bearing and pressing device has a spring device which exerts a load on the rotor or on an element that is capable of performing a wobbling movement.
