る。However, in the conventional concentration measurement using the filtration gravimetric method, when the concentration of suspended solids is low, it is necessary to collect a large amount of sample water to obtain a predetermined amount of suspended solids, and filtration takes a long time. In addition to this, there are problems with waste disposal of a large amount of sample water after filtration (especially in the case of radioactive liquids), and depending on the type of suspended solids, they may dissolve due to oxidation during the first filtration operation and may dissolve during measurement. There are disadvantages such as reduced analysis accuracy and risk of exposure to radiation.

かできる。The present invention has the above-mentioned configuration, in which a sample line is arranged as a bypass path in a distribution line for a liquid containing suspended solids to be sampled, and a filter holder is attached and detached in the sample line through which the sample liquid is distributed. At the same time, a differential pressure gauge for detecting the differential pressure across the filter holder is attached to the filter holder, and a flow rate control valve and an integrated flow meter are installed at the front and rear of the sample line. The sample liquid mixed with suspended solids flowing through the sample line can be bypassed into the sample line whenever desired, and the sample liquid flowing through the sample line can be controlled at an appropriate flow rate by a flow rate control valve. The suspended solids are efficiently captured by the filter holder, and the captured sound is detected by the differential pressure gauge, and the amount of sample liquid flowing into the sample line is also detected by the integrating flow meter. By detecting the sample flow rate and detecting the sound of suspended solids captured by a differential pressure gauge, it is possible to detect the suspended solids concentration in the suspended solids-containing liquid flowing through the distribution line at any time and with great ease. At the same time, the suspended solids can be captured by a filter holder and taken out for analysis.

Since the suspended solids are captured, the accuracy of detecting the concentration of suspended solids and its analysis accuracy are significantly improved, and since the sample liquid is returned to the distribution line of the liquid containing suspended solids, there is no need to treat the waste liquid. Furthermore, there is no risk of contamination such as radiation exposure due to the liquid mixed with solid matter in the suspension.
