It can be applied to high temperature and high-pressure occasions.The measurement accuracy can reach +-1~2%.The structure is simple, firm, stable, and reliable, long service life, and low price.The advantages of throttling differential pressure flow meter: It accounts for about 70% of various flow measurement methods. Countries around the world are generally used on more important occasions. This method of using differential pressure to measure flow has a long history and is relatively mature. Most meters are also equipped with flow totalizers to display the cumulative flow for economic accounting. Since the differential pressure and the flow have a square root relationship, the flow display instruments are equipped with a square root device to linearize the flow scale. The differential pressure-sensitive components of differential pressure meters are mostly elastic components. The secondary device is a variety of mechanical, electronic, and combined differential pressure meters equipped with flow display instruments. The primary device of the differential pressure flow meter is often a throttling device or a dynamic pressure measuring device (pitot tube, velocity tube, etc.). It receives the differential pressure signal generated by the measuring element and converts it into the corresponding flow rate for display. The secondary device is called a display instrument. It is used for the secondary device to display the flow. It produces a pressure difference proportional to the flow (velocity). It is installed in the pipeline of the fluid to be measured. The primary device is called the flow measuring element. The differential pressure flow meter consists of a primary device and a secondary device.
