GAS DENSITY MONITOR COMPRISING A TRANSMISSION ELEMENT, AND GAS DENSITY MONITORING METHOD

摘要

In order to improve the accuracy of the density monitor 22 for monitoring the gas density of the test volume, the density monitor 22 according to the invention is connected to the test volume in such a way that it moves in the test volume when the gas density changes And a membrane movement detection device 26 connected to the membrane 24 for converting the movement of the membrane into an electrical signal and wherein the membrane movement detection device 26 mechanically amplifies the membrane movement path And is connected to the membrane 24 by a transfer element 28 for the purpose of controlling the flow of the fluid.
