VOLUME MEASURING DEVICE FOR GAS PRODUCED BY REACTION OF MICRO-ORGANISM IN REACTION TANK AND MULTI CHANNEL TYPE AUTOMATIC GAS ANALYZING SYSTEM COMPRISING THE SAME

摘要

This invention relates to the generation amount measuring device, a controlled amount of water is filled in the central part, one end of which is open so as to be exposed to the outer space of the atmospheric pressure U- shaped tubes; But provided with three ports including a first port to a third port, the first port is connected to a closed reaction vessel through a pipe, the second port is exposed to the outer space of the atmospheric pressure, the third port is a tubing It is connected to the other end of the U- shaped tube through the reaction tank and the U- shaped or U- shaped tube between the tube and the flow control means is selectively controlled to connect through the external space; And positioned at a predetermined height of one U- shaped tube, the level of water filled in the U- shaped tube detect if the optical sensor has reached a predetermined level to generate a signal; And an optical sensor, and the flow control means and electrically connected to, the counting by receiving signals from the light sensor, and control means for controlling the flow control means according to the received signal, the generation amount measuring device comprises a By providing, conveniently the amount of gas produced by the reaction of the anaerobic or aerobic microorganisms in a sealed reaction vessel in an automated way can be quantitatively measured accurately, but also, and accurate and easy change of the amount of the reaction duration so it can be measured.
