AI Technical Summary
Technical Problem
When a vortex gas flow meter is in use, impurities in the gas adhere to the blades, causing the flow signal to be distorted and the blades to age, which affects the measurement accuracy.
Method used
The high-pressure gas inside the second airbag plate is ejected through the jet nozzle to flush the blades of the vortex generator, remove adhering impurities, and the reset speed of the movable plate is controlled by the damping rod to protect the piezoelectric sensor.
Benefits of technology
It improves the precision of gas flow measurement, reduces the impact of impurities on the rotation of the vortex generator, protects the sensor inside the metering tube, and ensures the normal operation of the device.
