Measuring the turbidity of water is an important step in testing its quality, since it is one of the methods for determining whether it is safe to use. Today, there are many methods for measuring the turbidity of water, some of them are designed specifically for regular research, others are used to monitor the quality of water associated with the use of process control. The paper discusses the method of monitoring turbidity of river water at the water intake of the utility enterprise (KP) “Ivano-Frankivsk Water-Eotechprom” using the sensor of turbidity developed as a component of the distributed (WEB-oriented) water turbidity monitoring system. The system automatically shuts off the flow of river water for purification with a sharp increase in water turbidity. The development of the technique is due to the complex topography of the Bystritsa Nadvornyanskaya river bank, which is why water is forced into the turbidity sensor using a centrifugal pump to a distance of 150 m, which introduces a significant error in the results of turbidity measurement. The experimental stand on which the process of supplying water to the turbidity sensor is modeled is considered, the choice of parameters is justified (geometric - length and diameter of the pipeline, distance from the sensor to the centrifugal pump; and technological - rotational speed of the pump, installation in the sensor and after the turbidity sensor, etc.) that affect the measurement results, as well as the methodology for conducting experimental studies. The obtained results are presented, which form the basis of the method for monitoring the turbidity of river water, which is implemented in the developed system for monitoring the turbidity of water for the utility company Ivano-Frankivsk Water and Ecotechprom.
