Abstract

The paper presents an analysis of the existing structures of thermal energy metering systems and the equations for calculating thermal energy amount used in these systems. The authors defined a complex for calculating the integral amount of energy between two points of heating system. This complex is a part of each equation used for the thermal energy metering systems. The algorithm is developed for automated calculating the thermal energy amount for systems based on standard pressure differential devices. It implements a complete mathematical model of a differential pressure flowmeter.
