Designed for recording, registration of remote monitoring of heat consumption and heat parameters in two open and closed systems of water heating systems, each of which can contain lines: supply, return and hot water, fe…Plus

The operating principle of electromagnetic flowmeters is based on the ability of the liquid to bring the electric current as it moves in a magnetic field. That is, electromagnetic energy meter is used in the phenomenon o…Plus

Ultrasonic heat meters operate on the principle of changing the time of the ultrasonic signal from the source to the receiver signal, which depends on the rate of flow. The basic principle of any one of them is similar t…Plus

The device gives the signal of fire in case of raising of ambient temperature

Power transformers with air-cooling, called dry transformers. Natural air cooling, the heat from the heated parts of the transformer a natural flow of ambient air, is sufficient for a small power transformer to winding v…Plus
