With the growing shortage of energy, more and more people pay attention to energy conservation, so pay attention to the energy measurement, measurement of thermal energy which has been a huge development. The accuracy of the experimental heat meter is in the heat meter standard apparatus. Its structure and working principle and the general liquid flow standard device are basically the same, except that it uses the media needs to be measured at different temperatures, such as 50 ℃, ℃. Commutator general liquid flow standard device 85 is open, and the commutator on the water heater is closed, because if the use of open commutator, then the water is likely to evaporate when the water temperature is higher, resulting in inaccurate measurement. Also from personal safety to consider, open commutator easy splashing liquid, at high temperature, people may be burned. Both in the structure is very different. 1. Closed application commutator heat meter standard device system. Heat meter standard device with closed commutator, the temperature water tanks, pumps, test piping, flow meters, commutator, weighing equipment, control equipment, heating systems and other components. 2. Open the commutator applications typically use liquid flow device open commutator, commutator open by the inlet nozzle, the deflector rotation axis, partitions etc. Closed and open commutator commutator working principle is the use of mechanical components to change the flow direction, but because of its structure, so that they are used in different devices. |
