1.Standard throttles are universal and approved by the International Standards Organization. They can be used without actual flow calibration and are the only ones in flow sensors;
2.The structure is easy to copy, simple, strong, stable and reliable performance, and low price;
3.Wide range of applications, including all single-phase fluids (liquid, gas, steam), partial mixed-phase flow, the diameter and working state (temperature, pressure) of the general production process can be measured;
4.Detection parts and differential pressure display instruments can be produced separately from different manufacturers, which is convenient for professional scale production.
