Abstract: The invention refers to a fouling detection setup (I) and method for determining the amount of fouling (5) of surfaces (3) of fluid (6) treating devices (2) and/or internal functional components (4) of such devices, which are exposed to said fluid and are subjected to fouling. Fouling detection setups and methods are useful for monitoring the amount of fouling of surfaces, e.g. heat-transfer surfaces and also for monitoring the cleaning procedure of such fluid treating devices and/or internal functional components of such devices. According to the invention the detection setup (I) comprises at least one first sensor (7), with means (9) for measuring the optical transparency T and/or electrical conductive conductivity Q of said fluid (6). The Sensor includes at least one sensitive area (8) that is located nearby and/or within said surfaces (3) and wherein said area is at least temporarily exposed to said fluid (6).

Abstract: The invention relates on an oval gear meter for volume flow measurement comprising a housing with an oval gear chamber with a fluid inlet and a fluid outlet, a pair of oval gear wheels positioned in the chamber and together forming an intermeshing or non-intermeshing involute toothing, and a contactless magneto-reactive sensor means positioned outside of the chamber. At least one of the oval gear wheels is provided with at least one permanent magnet to form a trigger wheel. The sensor means is positioned in an appropriate position relative to the trigger wheel so that the sensor means is adapted to measure the rotation of the oval gear wheels by measuring the rotation of the trigger wheel. The trigger wheel is provided with a permanent magnet that generates a generally homogeneous magnetic field along one axis of symmetry of the trigger wheel so that the magnetic field is generally symmetrical relative to the rotational axis of the trigger wheel.

Abstract: The invention relates to a commercial dishwashing machine, where the detergent added to the first wash tank of the wash section is controlled by a regulator which controls a dosing device. The regulator is a fuzzy regulator, which in a learning phase determines characteristic influencing values of the system to be regulated. In the learning phase, detergent is continuously added to the first wash tank for a predefined period. The change in the water's conductivity over that period is determined. In the subsequent operating phase, the extent to which the conductivity measured deviates from a set value is determined. Dosing takes place by fuzzy regulation on the set value deviation, on the basis of the measured influencing values as fuzzy variables. Because in the learning phase all the influencing values of the dishwashing machine, dosage device and detergent are taken into account, dosing is automatically optimally adjusted to prevailing conditions.
