The individual energy monitor in a multiple unit complex includes means for measuring the temperature differential at the inlet and outlet of each consuming unit. An on-site microprocessor functioning as a muliple meter unit is coupled to all such consuming units and stores the temperature differential with appropriate processing to record the heat usage during a known time. The microprocessor meter can store the individual energy usage of many consuming units and can be remotely or locally interrogated for purposes of collecting of the necessary data when and as required for billing and the like with equitable allocation of costs among the units based on such individual energy usage. The microprocessor meter continuously, sequentially and cyclically reads the inlet/outlet temperature sensors. The metering system may assume that the total fluid flow from the heat source unit is divided essentially equally amongst the several flow paths to directly allocate costs or may weight the temperature differential in accordance with various factors such as the flow resistance of each path, the flow characteristic of a common circulation pump, the output of a single flow sensor connected to detect the total flow rate, the actual opening of each consuming unit, and even the individual monitored flow through each consuming unit.
