Abstract:
A filling machine comprising:a plurality of filling pipes placed in proximity to each other for injecting fluid into each of a plurality of containers; a valve provided for each of said filling pipes for opening and closing each of said filling pipes based on an open and a close signal respectively; an electromagnetic flow meter provided for each of said filling pipes for calculating a flow based on electromotive force generated by applying an alternating magnetic field to said fluid in each of said filling pipes and outputting a flow signal; control means for outputting said open signal to each of said valves, and also outputting said close signal to each of said valves based on said flow signal outputted from each of said electromagnetic flow meters after outputting said open signal so as to fill each of said containers with a fixed amount of said fluid; exciting frequency setting means provided in only one of said electromagnetic flow meters for generating a synchronous signal having a desired frequency; and synchronization means for transmitting said synchronous signal to all the other electromagnetic flow meters for performing excitation in synchronization with said synchronous signal.
