Should pressure gauges and thermometers be installed on both the inlet and outlet pipelines of the cooling circulation system in the plant area? Do all of them require remote access? How do you usually do it? Is it necessary?
For pressure gauges and thermometers, only the main pipe of the unit needs to have remote transmission; this is usually located in the boundary area. Individual heat exchangers do not require pressure gauges – a local thermometer at the return water side is sufficient. Of course, if you have plenty of money, there is no limit to the number of instruments that can be used
Local thermometers are installed on each supply and return branch pipe, while local pressure gauges are installed only on the supply branch pipes； A remote thermocouple and a pressure transmitter are installed on each of the supply and return main pipes in Sheung Shui
Generally speaking, if installation is desired, it should be done on the outlet pipeline; as for the water inlet side, one can simply consider the operating conditions of the water tower to determine the efficiency of heat exchange
First, it depends on whether the process you have designed is a high-end automated one Some owners want these things. Personally, I think it’s sufficient as long as normal operation can be ensured. In other words, circulating water is used for on-site pressure gauges and thermometers; for cold water, pressure gauges and remote temperature sensors need to be installed on the main pipes. Installing pressure gauges before and after the heat exchanger allows one to determine the pressure loss across the heat exchanger, which indicates that it is time to clean it if it is blocked. Do you understand? For many things, it’s not only the design that needs to be considered, but also the ease of operation and maintenance. Remote transmission can help reduce costs; inexpensive on-site meters can solve many problems
