There is a shortage of freshwater resources in coastal or nearshore areas. Desalination is an important solution to water shortages in these areas. During the seawater desalination process, data such as flow rate and liquid level need to be monitored. Monitoring of these data ensures that the system is operating properly.

Natural gas undergoes a long process of transportation pipeline transmission, filtration, odorization, and pressure regulation from extraction to end-user consumption. In this process, monitoring the pressure and temperature within the pipeline is critical to ensuring the proper operation of the system.

The MVR evaporation equipment requires the use of intelligent pressure transmitters to monitor the liquid level in the separator for feed control. It also monitors the liquid level in the condensate tank, providing timely water replenishment for the condenser, allowing it to condense rapidly. Concurrently, the liquid level height of the raw material tank and the mother liquor tank is monitored. When the liquid level is depleted, raw liquid is added to maintain the normal progress of the process. Intelligent temperature transmitters are used to monitor the steam temperature in the heater, continuously heating the raw liquid for the separation of the solution and the solute. It also monitors the temperature of the separator cavity for efficient separation of the solute and solvent. Flowmeters are used to calculate the volume of the raw material liquid in the feed pump, accumulating the flow.
