A DEVICE FOR CONSECUTIVE MEASURING RESIDUAL CHLORINE IN WATER DISTRIBUTION SYSTEM

摘要

An apparatus for measuring the residual chlorine continuously in the water service network system is provided to allow the accurate concentration of residual chlorine to be predicted even in case of the change of temperature. An apparatus(1) for measuring the residual chlorine continuously in the water service network system collects the filtered water of a filtration plant to calculate the water reaction coefficient (Kb) obtained by considering the effect of temperature, and measures the residual chlorine at the specific point of the network to calculate the pipe wall reaction coefficient (Kw), thereby predicting the concentration change of residual chlorine in the water service network system, wherein the apparatus comprises a small-sized tank(10) where the collected sample is filled and which is pressurized by a pressure lever(12) and is provided with a temperature controller(14); a buffer tank(20) which controls the flux of the sample discharged from the small-sized tank to relieve the instantaneous change of the discharge amount when the pressure lever is operated; a metering pump(30); a sensor which senses continuously the concentration of residual chlorine of the sample flowing with constant flux and velocity by the metering pump; and a display unit(40).
