摘要: A method and to an arrangement for ultrasonic flow measurement according to the transit-time method is provided for accurate and non-invasive flow measurement independent of the viscosity. At least one sound transducer pair is provided that has a clamp-on ultrasonic transducer operating in transmitting operation and a clamp-on ultrasonic transducer operating in receiving operation. The cross-section of a measurement tube through which a gaseous or liquid medium flows is substantially a pentagon having a base side and having sides adjacent at right angles and having sides adjacent thereto and lying opposite the base side, which include an angle of less than 180°. The sound transducer pair is arranged on the base side in order produce first sound paths. Because of flattening of the vertex lying opposite the base side, the same sound transducer pair additionally produces a second sound path.

摘要: The disclosure relates to a measurement of the wall thickness of samples such as pipes, containers or panels in which the interior or underside is inaccessible and to a measurement of the layer thickness of coatings or linings of the samples. Disclosed are special measuring arrangements using ultrasonic transmitters and ultrasonic receivers with pitch-catch and pulse-echo configurations, and the associated method for determining the wall thickness without prior knowledge of the sound velocity in the sample. Measuring individual layer thicknesses of a multilayered system without prior knowledge of their sound velocities is also disclosed. The method and the measuring arrangement allow the wall thickness to be measured independently of the knowledge of the sound velocity of the sample. This reduces the measurement uncertainty for the wall thickness and inner diameter of the pipe and thus reduces the measurement uncertainty for a clamp-on ultrasonic flow meter.

摘要: A joining method is for producing a sound transducer system. The method includes: providing a piezoelectric material and a plurality of components, each of the components being characterized by a solidus temperature; arranging the piezoelectric material and the plurality of components in the form of a stack, so that adjacent to a front face of the piezoelectric material there is a front stack part and adjacent to a rear face of the piezoelectric material there is a rear stack part; and consolidating the stack by the introduction of heat and pressure for a predetermined period of time, none of the solidus temperatures of the plurality of components being exceeded during the consolidation; and, during the consolidation, the piezoelectric material being directly acoustically coupled to an immediately adjacent component of the front and/or rear stack part.

摘要: A method and an arrangement for ultrasonic clamp-on flow measurement with the aid of an off-center sound path measurement via clamp-on ultrasonic transducers being fastened to an intermediate piece of a process pipe. Center sound paths as well as off-center sound paths are taken into account for the flow measurement via the arrangement and method. The arrangement for measuring flow includes a process pipe, through which a liquid or gaseous process medium flows, and an acoustic transducer pair and second clamp-on ultrasonic transducer operating in receive mode is disposed on the process pipe where two bodies are disposed on the inner wall of the process pipe to aid the off-center measurement.

摘要: The invention relates to a method and an arrangement for an ultrasound clamp-on flow measurement according to the transit-time method. The problem addressed by the invention is to provide a measurement arrangement for clamp-on flow measurement, which enables measurement using only two pairs of acoustic transducers in both reflection configuration and in X configuration, without requiring the acoustic transducer position to be changed when switching between configurations. For the method according to the invention, at least four acoustic transducers are arranged on a measurement pipe, which are controlled in such a way that the flow measurement is performed consecutively in an alternating manner in the X configuration and in the reflection configuration. For this purpose, two acoustic transducers are connected for each transmission-receiving pair for a flow measurement in X configuration, and/or two acoustic transducers are connected for each transmission-receiving pair for two reflection configurations.
