<P>PROBLEM TO BE SOLVED: To provide a liquid sampling/measuring system facilitating the maintenance and capable of reducing the cost by a possible simple structure. <P>SOLUTION: The liquid sampling/measuring system includes a sub-line that is branched from a main line and communicated with the main line, the sub-line is formed with a sampling/measuring mechanism unit, and the sampling/measuring mechanism unit is sequentially provided with a back pressure valve and a measuring instrument towards the downstream side. During operation when the main line passes liquid, the back pressure valve is "open" to alow measurement liquid, or processing liquid to pass through the measuring instrument disposed in the downstream side and, when stopping the operation where the main line passes no liquid, the back pressure is "closed". The liquid sampling/measuring system is configured to measure the liquid quality by the measuring instrument installed in the downstream side during the operation when the back pressure valve is "open". <P>COPYRIGHT: (C)2012,JPO&INPIT |
