Method and apparatus for control of a process for processing goods (2) with liquids (3). The transport of liquid to and from the goods being controlled by the physical state of the process goods, which is sensed by sensors (6). At a predetermined condition of the process goods sensed by the sensors, the transport of liquid is interrupted or changed by the valve means (4) and by the control unit (8), receiving sensor signals (7). By coordinated quantity measuring (5) of the transport of liquid and by sensing of said sensors the process parameter values are established for control of the process. Method and apparatus (206) for optical controlling and/or monitoring of fluid systems and fluid components. Light is emitted by light emitting means (204), included in an optical link (199), comprising a light guide (197), at least two series-connected optical sensors (194, 195) and/or transducers (205) and detecting means (201). The combined signal (200) received is analysed, sensor signals generated by control and monitoring sensors being separated for generation of corresponding control or monitoring signals (202, 203). Flow throttling-measuring device for fluids, comprising a first main chamber for quantity measurement including a sensing zone (III), an inlet zone (II) and an outlet zone (IV) and a second main chamber (I) and a third main chamber (V) intended for flow regulation. Disordered flow generated in the second main chamber and the third main chamber is transformed in the inlet zone (II) and the outlet zone (IV) to a flow necessary for the sensing zone (III) of measuring reason, in which sensing zone (III) the fluid obtains a recordable velocity proportional to the volume flow which passes the device. |
