Abstract: The device serves for the qualitative and quantitive detection of particles in a fluid and includes a light source (1), an optical sensor (2) and a sample carrier (4) which is arranged therebetween and which is for receiving fluid to be examined. The sample carrier is (4) movable relative at least to the sensor (2) and is connectable via a fluid inlet (9) to a conduit (11) for feeding the fluid, and via a fluid outlet (10) to a conduit (12) for the discharge of fluid. The sample carrier (4) is exchangeably arranged in a receiver of the device, so that this sample carrier can be replaced by another one in a rapid and simple manner when the sample carrier (4) is contaminated.

Abstract: A method serves for operating an electronically controlled pump assembly (1), with which setting parameters of the pump (2) can be adjusted in an electronic control (6), for adaptation to the hydraulic demands of the location installation situation (4, 5). Operating data is registered during the operation of the pump assembly (1). After a predefined time and on the basis of the registered operating data, it is examined as to whether the pump assembly (1) has been set vis-à-vis the factory settings. If this is not the case a signal (11) is issued in order to point out the necessary setting.

Abstract: A method for the quantitative and/or qualitative detection of particles in fluid, with which the fluid to be examined is introduced into a beam path of an optical device, between at least one light source and the image acquisition sensor with a matrix of light-sensitive cells. Pixel values of the cells are detected and the distribution of the pixel values is at least partly determined. The pixel value or values which have been determined most often are used as a value or average value for a background signal. A signal is outputted or the method is interrupted, on reaching a maximal permissible value for the background signal.

Abstract: A method serves for determining particles (3), in particular bacteria in fluid and operates using an imaging optical device with a light source (1), with an optical sensor (4) with a field of light-sensitive pixels and with a fluid sample, which is to be examined, arranged between the light source (1) and the sensor (4). Characteristics of at least one particle (3), which is detected with regard to imaging, are compared to characteristics of a characteristics collection for determining the detected particle (3). The image acquisition is effected with darkfield technology and a light-sensitive pixel comprises several subpixels which are used for image acquisition.

Abstract: A centrifugal pump assembly includes an electric motor (2) driving a centrifugal pump (1) and includes an electronics casing (8). In the electronics casing (8), the control electronics (10, 11) for the pump and motor are integrated. A device for detecting particles in a fluid fed via a bypass (6, 7) of a delivery conduit (3) is also in the electronics casing (8).
