Abstract
A sampled flow of water is extracted from a water conduit 1 carrying impure water by a sampling tube 2, the pressure at a point in the sampling tube is kept constant by a constant pressure maintaining valve 4, and the sampled water passed through a filter 7. The flow rate of sampled water passing through the filter 7 is measured by a flow meter 8. A value corresponding to the total amount or level of impurity in the sampled water is evaluated by an operation circuit 9 at a prescribed time interval, based on the time-dependent change in the result of measurement of the flow meter 8 and the total amount or level of impurities in pure water is thus measured indirectly.
