Abstract: In a method for selecting products via the Internet, an Internet connection is established between a customer-side client-computer, which contains a planning module, and a manufacturer-side server, which contains a product database. After selecting at least one product line from the product database by querying of basic data via the Internet, a first identifier characterizing the selected product line is transmitted to the client-computer by the server. The specifying of a product of the product line is done with the help of the planning module by local querying of application data at the client-computer using the planning module. The first identifier can then be expanded to a second identifier uniquely characterizing the specified product. No transmitting of application data to third parties via the Internet is required.

Abstract: The invention relates to a method for determining and presenting an optimized arrangement and assembly of a measurement system of process measurement technology, especially of a radiometric measurement system, at a container or pipe, in which measurement system at least one characterizing parameter of a medium contained in the container or pipe is to be measured. The method proceeds with the aid of at least a first electronic computer (10) and a second electronic computer (11) connected therewith and containing a display- (12), a processor-controlled, data processing- (15) and an input-device (13), wherein container- or pipe-specific data and information on medium and on expected measurement range are taken into consideration. The method establishes therefrom an optimized arrangement of the measurement system at or on the container or pipe and presents this arrangement in a sketch.

Abstract: The invention relates to a device for determining and/or monitoring the density and/or the level (L) of a filling material in a container. A transmitting unit which emits radioactive radiation and a receiving unit which is arranged in such a way that it receives the radioactive radiation or the secondary radiation that is produced by the interaction of the radioactive radiation with the filling material are provided. A regulating/evaluating unit which determines the density and/or the level of the filling material in the container using the measuring data that is supplied by the receiving unit is also provided. The aim of the invention is to provide a device which enables the level or the density of a filling material in a container to be measured reliably. To this end, the receiving unit consists of individual detector units.

Abstract: A level measurement device for measuring the level of material inside of a vessel which includes a conductive element, a signal generating unit, and a receiving unit. The conductive element does not come into direct contact with the material being measured. The signal generating unit generates measurement signals which are transmitted along the conductive element. Each of the measurement signals produces an electromagnetic field which travels along the conductive element and is reflected when it reaches the surface of material in the vessel. The reflected electromagnetic field produces an echo signal which travels along said conductive element to the receiving unit. The receiving unit receives the echo signal and determines the level of material in the vessel. The conductive element can be located outside of the vessel.

Abstract: A liquid level meter is provided for measuring a level of a liquid (1) in a container (3), which meter measures acceptably in the case of liquids with low dielectric constants, and the installation and maintenance of which are simple and cost effective. This meter comprises an electronic circuit (13), which generates electromagnetic signals in operation, a conductor (7), which projects into the container (3), along which a float (11, 11a, 11b, 11c, 11d, 11e) moves along with the level, which has at least one segment reflecting electromagnetic signals, an injector (9), which transmits the signals from the circuit (13) to the conductor (7), which conductor (7) leads the signals into the container (3) and leads out a signal reflected at the float (11) and a receiving and evaluating circuit (15), which receives the reflected signals, which determines a travel time of the signals and which ascertains the level from the travel time.

Abstract: The instant invention relates to a method to compensate for extraneous radiation caused by the effects of intermittent active radiation sources (not effects due to cosmic or terrestrial radiation) that can cause errors in radiation measured values. For the purposes of suppressing these extraneous radiation effects in radio-active measuring methods, the commencement and termination of the extraneous radiation and the attainment of a stable condition in the extraneous radiation are determined. The difference between the measured value (before commencement of the extraneous radiation) and the measured value (on attainment of the stable condition) is determined. The measured value is then reduced by the determined difference for the duration of the extraneous radiation.
