| titleOfInvention | Flowmeter transition time measuring device based on micromechanics piezoelectric supersonic wave transducer |
| abstract | The utility model discloses a kind of flowmeter transition time measuring devices based on micromechanics piezoelectric supersonic wave transducer.Mutually independent ultrasonic wave transmitting and receiving module are installed in the radial tiltedly opposite side of pipe under test, and two modules are separated by fluid to be measured；The ultrasonic wave transmitting module and ultrasonic wave receiving module is all made of micromechanics piezoelectric ultrasonic transducer array module；The micromechanics piezoelectric ultrasonic transducer array module bottom is basal layer, basal layer is equipped with transducer unit, transducer unit is successively formed by stacking by hearth electrode, piezoelectric layer and top electrode, and hearth electrode and top electrode pass through connecting line respectively and be connected from different terminals.By being arranged in, pipeline is radial tiltedly successively to be emitted mutually respectively along the downbeam of fluid and countercurrent direction to two pieces of independent micromechanics piezoelectric ultrasonic transducer arrays in direction and receives ultrasonic pulse the utility model, the transition time that ultrasonic wave concurrent-countercurrent is propagated is measured, for calculating fluid flow rate and flow. |
