Abstract:
A fluid analysis system (10) is provided for analysis of a fluid flowing in a pipe or in a pipeline. The fluid analysis system (10) comprises a pipe portion (12) which, when the fluid analysis system is put to use, forms a part of the pipe or the pipeline through which the fluid flows. The pipe portion (12) is provided with a fluid sample outlet (35) for withdrawal of fluid samples from the fluid flowing through the pipe portion (12) and a fluid sample return outlet (36) for returning fluid samples to the pipe portion (12), where the fluid sample return outlet (36) is arranged downstream of the fluid sample outlet (35). The fluid analysis system (10) further comprises a fluid analyser (16) which is provided in fluid communication with the fluid sample outlet (35) and the fluid sample return outlet (36), and a propeller unit (22) which is provided with at least one upstream propeller (29) and at least one downstream propeller (30). The propeller unit (22) is mounted in the pipe portion (12) in such a manner that the upstream propeller (29) is located upstream of the fluid sample outlet (35) thereby enabling the upstream propeller (29) to mix the fluid in the pipeline before fluid samples are withdrawn through the fluid sample outlet (35), and in such a manner that the downstream propeller (30) is located downstream of the fluid sample outlet (35) and upstream of the fluid sample return outlet (36), thereby enabling the downstream propeller (30) to provide a pressure drop in the pipe portion (12) between the fluid sample outlet (35) and the fluid sample return outlet (36) which is sufficient to drive the fluid samples through the fluid analysis system (10). A method is also provided for operation of a fluid analyser (16).
Abstract:
The invention relates to a particle counter apparatus for counting particles in a fluid flowing in a pipe or a pipeline. The particle counter apparatus comprises a pipe portion through which the fluid flows, where the pipe portion is provided with a fluid sample outlet for withdrawal of a fluid sample. Furthermore the particle counter apparatus also comprises a first fluid transfer body extending from the fluid sample outlet to a particle counter, and a second fluid transfer body extending from the particle counter to a fluid return outlet mounted in the pipe portion downstream of the fluid sample outlet. In the pipe portion there is mounted a propeller unit comprising a propeller and a generator, with the result that particles are distributed uniformly in the fluid before the withdrawal of fluid samples, and electric power is provided for operation of the particle counter apparatus.
Abstract:
A pipeline pig (10) for inspection and cleaning of an inner wall (13) of a pipeline (12) is described. The pipeline pig comprises an elongate body (15) having a forward end portion (16) and a rear end portion (17), and a central portion (18) which, during pigging of a pipeline (12), is adapted to clean the inner wall (13) of the pipeline. The pipeline pig (10) is provided with a camera unit (21) such that the camera unit, during pigging of a pipeline (12), can take images and/or video film of the inner wall (13) of the pipeline. The pipeline pig (10), during pigging of a pipeline (12), is independent of external connecting means such as hoses, cables and/or other means.
