| 7. | Application of time difference type ultrasonic flowmeter in large - bore circulating water pipe 时差式超声波流量计在大口径循环水管道的应用 |
| 8. | In the past , piezoelectricity transducer was adopted usually in the ultrasonic flowmeter development , so in higher temperature , for example , exceeds 150 " c , the measurement was not carried out 以往的超声流量计均采用压电超声换能器进行测量,这样在被测流体温度较高,超过150的情况下,就无法进行测量了。 |
