IPC: G01N33/18
Filed: 1990-06-08
Abstract: PURPOSE:To make it possible to shorten useless time required for the preparation for measure ment by providing a flow-rate regulating valve, fully opening the valve before the measure ment, conducting a large amount of water to be measured through a sample water pipe, and washing out the sample water used in the previous measurement. CONSTITUTION:A flow-rate regulating valve 5 is fully opened before measurement. Aqueduct water 2 of a main pipe 1 is made to flow through a sample water pipe 3. Sample water 9 which is used in the previous measurement is washed out. The valve 5 is opened to the adequate degree in measurement. Part of the aqueduct water 2 flowing through the main pipe 1 is made to flow through the water pipe 3 as the sample water 9. The water quality of the sample water is measured with each sensor 6 at a measuring part 4. Namely, the concentration of the object to be detected such as residual chlorine contained in the sample water 9 is detected with the sensor 6 as the electric conductivity and the like of the sample water 9. The concentration is converted into the numerical-value signal in a data processing device 7, and the signal is sent into a monitoring and controlling board 8. In this way, the effect of the remaining sample water in the previous measurement in the measuring part 4 is excluded in a short time by the flow of a large amount of the water before the measure ment, and the measuring environment is quickly formed in the measuring part 4. Therefore, the useless time can be shortened.
