The problem of Cun Zaiing as can be seen:
1, owing to be static reading, open, stop that tested table can be subjected to air-flow inertia impact amount in the process at bell jar, make the flow distortion of tested table running, particularly minimum, the maximum flow point influence is bigger in calibrating.
2, promoting bell jar is manually-operated, and it is inhomogeneous to exist pulling speed, and the fluctuation of bell jar cylindrical shell is big, influence calibrating quality.
3, the temperature of medium and pressure, the temperature of tested table are manually to read in the bell jar, easily produce personnel's number reading method error.
4, verification result adopts artificial calculating, calculates loaded down with trivial detailsly easily to make mistakes, and owing to reasons such as artificial value, correction choice also easily produce error,
5, the calibrating flow is by manual shift, and the pressure of being unrealized, temperature compensation are revised in real time.
Technology contents
