Measuring system of gas flow velocity in heavy pipe |
| |
| Abstract: | Adopting gas ionized technology,gas flow velocity in heavy pipe is measured,influence of gas ionized technology and the configuration and bias voltage on detecting plates on measuring system is examined by experiments.A Φ630#mm pipe measuring system with β ray ionization is designed.Testing result indicates that the measuring accuracy of the system is in the range of 3% and it has fair capability of anti disturbance and anti pollution. |
