Abstract [en]

In this thesis, a solution to measure and track the ow in beverage pipes non- intrusively have been proposed. Di_erent ways to track uid ow have been analyzed, and the selected measurement system, ultrasonic time of ight, have been modelled with the help of Beam Tool 8 and simulated with Finite element analysis in Comsol Multiphysics. The result from this simulation was used in creating a prototype by using a ultrasonic front end solution from Texas Instruments. A Texas Instruments TDC1000-GASEVM evaluation module was also tested on the system to try to get the transmitted signal to a high enough output level to be detected by the receiving module. A test rig able to simulate the ow in a pipe containing beer was made to be able to get a accurate test system, before a eventual test on a real pipe system would take place. The results from the testing shows that due to a bad choice in material for a wedge and no proper matching layer on the transducers, a lot of the energy from the transducer is reected back. This made the proposed system not able to measure the ow in a pipe, although with better choices in materials and transducers, it should be possible to get an accurate measurement.
