This Master's Thesis was made for Metso Automation PLC valve assembly factory. Job objective was to construct new automatic functions to the old test bench, to develop pressure control system and examine the possibility of automatically determine the integrity of the valve body and find the appropriate flow meter. The work starts with a brief statement of Metso's test procedure. After that has been done literature review about hydraulic elasticity, influence of temperature and measuring of flows to seek a suitable meter to measure the leak flow. The development and automation of test bench was designed to be operated by three options, the selected one was controlling a pump based system. Body integrity was examined on the basis of go...
