Methods of parameter measurement in testing hydraulic resistance. Unification of measuring instruments

Purpose: The study of heating networks; methods and technical equipment are proposed for testing heating networks.Methodology: The analysis of actual tests carried out on in the Tyumen region for heat networks with different diameter and heat supply sources, whether CHP or stand-alone boilers.Research results: Existing methods of organising hydraulic loss tests are evaluated, and the results obtained in the course of this work are analyzed. The test organization procedure is proposed to improve the parameter accuracy of thermal network state. The selection of computing equipment and determination of the most suitable ones for each type of tests.Value: The relevance of the topic under consideration is due to the imperfection of the requirements of the current regulatory and technical legislation of the Russian Federation for testing on heat networks of resource-supplying organizations. Existing test methods for thermal and hydraulic losses do not take into account the possibility of using modern instrumentation.
