ANALYSIS AND EVALUATION OF THE MEASUREMENT SYSTEM BASED ON KAMA ORIFICES FOR MEASURING THE FLOW OF SEWAGE IN THE LIGHT OF THE WATER LAW REQUIREMENTS

Aim of the study Analysis and evaluation of the operation of KAMA measuring systems in relation to the currently used other measuring devices and techniques to control sewage discharge in accordance with the requirements of the new WATER LAW. Material and methods Measurement data of controlled measuring systems KAMA R1500 and KAMA 1000 and characteristics of measuring devices from other producers. Results and conclusions Control measurements of KAMA measuring systems in a circular collector and in a rectangular open channel are presented as examples of the most common variants of geometry of drop points. The obtained accuracy of measurement of the flow rate of KAMA orifices were referred to other currently used techniques and measuring devices, indicating the most important reasons for lower than one would expect accuracy in this range. The awareness of the equivalence of the used devices and measurement techniques in constant monitoring of the flow rate of discharged wastewater may be helpful in a rational construction of the control and measurement system.
