Abstract: Device for mounting and demounting of a probe (12) to be arranged in an access tube to a process pipeline. It comprises an hydraulic cylinder (14), accessing the access tube (26) with a gripping tool (15) to engage a probe (12) for moving this probe into an operating position in the access tube and retrieving the probe from this position. A revolving unit (17) with at least two chambers (27, 28) is provided, each for accommodating an axially movable probe (12). The chambers (27, 28) are accessible by the gripping tool (15) to move a probe into a chamber and in a subsequent step from the chamber into the access tube. A power means (30, 31) is arranged for revolving the revolving unit (17).

Abstract: A method for measuring properties of a flowing fluid composition comprising at least two different components, while the fluid composition is flowing through a duct or channel, which flow meter comprises: at least one sensor (2, 3) in the shape of a cavity resonator through which at least a portion of the fluid composition passes; at least one electronic circuit (4) comprising a transmitting means (11) adapted to transmit an electronic signal (9) into the flowing fluid via a probe (7, 11); at least one receiving means adapted to receive a signal which has traveled through the flowing fluid composition; and at least one signal processing unit (12) adapted to deduce fluid specific signals from the received signals. An oscillator included in the electronic unit (4) may, in a preferred embodiment, be phase locked to the resonant frequency of the sensor (2, 3) (in a so-called FSA (feedback self-oscillating amplification) method).
