The application fields of differential pressure transmitters are very wide, mainly including the following aspects:
1、 Industrial automation control
Differential pressure transmitters are widely used in industries such as chemical, petroleum, natural gas, and petrochemical to monitor and control pressure, liquid level, and flow rate, ensuring stable and efficient production processes
In the power industry, it is also commonly used to monitor and control pressure changes of gases or liquids inside pipelines
2、 Flow measurement
Differential pressure transmitters are often used in conjunction with orifice plates, Venturi tubes, and other throttling devices to indirectly calculate flow rates by measuring the pressure difference before and after the fluid passes through the throttling element. They are widely used for flow measurement of liquids, gases, or vapors
3、 Liquid level measurement
In a sealed container, a differential pressure transmitter can convert the pressure difference between the upper and lower points into liquid level height by measuring it. It is particularly suitable for liquid level monitoring in open or sealed containers, such as storage tanks, reactors, etc
4、 Other special applications
In the filtration system, it is used to detect the pressure difference on both sides of the filter element and determine whether the filter is clogged
In a heat exchange system, it is used to monitor the temperature and pressure changes on both sides of the heat exchanger, determine the heat transfer efficiency, and check for scaling and other issues
It is also applied in the performance evaluation of steam trap valves, pump control monitoring, and monitoring of sprinkler systems
In addition, differential pressure transmitters are widely used in high cleanliness environments such as food processing and pharmaceuticals due to their reliability and ease of cleaning
