AI Technical Summary
Existing transducer testing equipment lacks the ability to simulate high-pressure gas environments, and the pressure control is inaccurate, failing to truly reflect the dynamic response and stability of the transducer in high-pressure gas.
A high-pressure testing device for ultrasonic transducers was designed, including an ultra-high pressure pipe section assembly and an ultrasonic flow meter main unit. Through the coordinated dynamic adjustment of the inlet valve and the pressure relief valve, precise pressure control is achieved, simulating high-pressure and ultra-high-pressure gas environments, and supporting multi-gas medium testing.
It enables real and reliable testing under high and ultra-high pressure environments, improves testing accuracy and functionality, supports transducer parameter optimization, extends service life, and reduces maintenance costs.
