摘要:
A method for a production of a heat exchanger for an inline measuring device includes the steps of: producing first opening provided for the connection of the heat exchanger to a temperature control piping system in a first sheet part serving for the production of one of the heat exchanger sheets; laying the first sheet part on a second sheet part serving likewise for the production of one of the heat exchanger sheets; producing an edge connection seam and inner connection locations by welding of the two superimposed sheet parts; introducing fluid through a first opening into a chamber remaining between the two sheets; superimposing a static pressure on the fluid in the chamber which exceeds a static pressure of a surrounding atmosphere to such a degree that an expansion of the chamber is initiated; and plastically deforming material of the thinner of the two sheet parts by expanding the chamber by means of the fluid with superimposed pressure.

The apparatus includes at least one heat exchanger secured on an inline measuring device. Temperature-control fluid flows through a heat exchanger, at least at times during operation, for the purpose of transporting heat. The apparatus additionally includes securement structure for the, especially releasable, fixing of the heat exchanger externally on the inline measuring device. The heat exchanger has an inner wall especially a trough- or dish-shaped inner wall, contacting the inline measuring device externally at least partially flushly, as well as an outer wall fixed to the inner wall. The outer wall is connected with the inner wall via a connecting seam running along an edge region and sealing against escape of the temperature-control fluid, and via a plurality of, especially point, or ring, shaped, inner connection locations, which are arranged spaced from one another in an inner region at least partially enclosed by the edge connection seam. Between the inner wall and the outer wall is at least one chamber having a plurality of sections communicating with one another and serving to convey the temperature-control fluid. The chamber is connected into a piping system conveying the temperature-control fluid via openings opening into the chamber.

摘要:
An apparatus for ascertaining, and/or monitoring, volume- or mass-flow of a medium flowing through a pipeline in the direction of the longitudinal axis of the pipeline. The apparatus includes: at least one ultrasonic sensor, which radiates/receives ultrasonic measuring signals at an angle of incidence/emergence into/out-of the pipeline; and a control/evaluation unit which provides, based on the ultrasonic measuring signals, information concerning volume- and/or mass-flow of the medium through the pipeline. The ultrasonic sensor includes at least one sound-producing element, a coupling shoe and a coupling adapter. The end region of the coupling adapter facing the coupling shoe has a securement mechanism for releasable securement of the coupling adapter to the coupling shoe. The end region of the coupling adapter facing the pipeline is embodied as a function of the pipeline in such a manner that it is form-fittingly securable to the pipeline.

An apparatus for ascertaining and/or monitoring volume- and/or mass-flow of a measured medium flowing in a flow direction through a measuring tube of predetermined inner diameter. The apparatus includes a plurality of ultrasonic sensors, which transmit and/or receive ultrasonic measuring signals along different, defined measuring paths, and a control/evaluation unit, which ascertains volume- and/or mass-flow of the measured medium in a pipeline/in the measuring tube on the basis of the ultrasonic measuring signals according to a sound entrainment method or the echo principle. At least two ultrasonic sensors, which transmit and/or receive the ultrasonic measuring signals on different measuring paths, are positioned in an opening located in the wall of the measuring tube.

An apparatus for determining and/or monitoring volume- and/or mass-flow of a medium flowing through a pipeline in a stream direction. At least two ultrasonic sensors are included, which are secured in a defined measuring positional relationship on the outer wall of the pipeline and alternately emit and receive ultrasonic measuring signal. A control/evaluation unit, which determines volume- and/or mass-flow of the medium in the pipeline on the basis of the travel time difference of ultrasonic measuring signals in the stream direction and opposite to the stream direction is also provided. For assuring rapid mounting and demounting of the ultrasonic flow measuring device on a pipeline, the at least two ultrasonic sensors are secured on a pliers-like clamping unit, which is embodied in a manner such that the ultrasonic sensors are brought into a measuring positional relationship by simple clamping onto the pipeline.
