Andrei Ivanov We live in a cold country - is a geographical factor that can not escape. And eat a lot of heat. For heating of residential and industrial buildings, in industrial processes. The trouble is that most of the heat produced is used inefficiently. Cheap heat developed the habit of not saving it. Today teplosberezheniya was pressing energy and economic challenge. In its decision, there are two sides - taking into account the real consumption and optimize the use of heat. Thermal energy is absorbed by one or another object (a building), is calculated as a function of flow rate, temperature and pressure coolant flow and return heating system at the boundary of the object. Therefore, the heat meter, in general, consists of two meters (one - in the flow, the other - on the return), two temperature sensors, as well as teplovychislitelya. At sites with high thermal loads are applied more and pressure sensors. Also to computational heat meter can connect one or more additional meters (water meters) to measure and record parameters of cold and / or hot water. There are also heat meters, providing accounting through several heat input, ie, for several pairs of "pitcher - the return pipe. Depending on their constituent flow, heat meters can be tach, vortex, ultrasonic, electromagnetic, and the like.
