Owing to adopted technique scheme, the utlity model has following advantage and effect:
1, the utility model can be under the working condition of medium-60 ℃～about 500 ℃ operate as normal.Wherein the capacitive detector resistance to shock is good, and distributed capacitance is little, and noise is low, and is highly sensitive, safe and reliable, practical;
2, the utility model is considered the demand of user's different levels, make high-performance capacitor formula detecting device and piezoelectric type detecting device have interchangeability, when the user need upgrade, only need a small amount of investment just the piezoelectric type vortex flow sensors can be upgraded to the condenser type vortex flow sensors.
3, ball valve jacking gear of the present utility model can be under situation about continuing to flow, and very conveniently changes quickly, the care and maintenance flow detector;
4, the part that contacts with medium of the utility model also can adopt stupalith or nonmetallic materials except adopting metal material, therefore can adapt to the flow measurement of the strong medium of corrosivity.
