1. Heat meters
1.1 Principles and definitions
The thermal energy meter measures the amount of heat given off or absorbed in an exchange circuit by a fluid known as the "heat transfer fluid".
Heat is conveyed from a production source to the devices used (heat emitters or heat absorbers) by a heat transfer fluid, which loops back to the production device without undergoing any change of state. The fluid most commonly used in heat exchangers is water...
