在近几年国外超声料位测量技术有了迅速发展,新一代的超声料位仪装有微机,并采用了判别接收数据、自动声速补偿、多路转换和电子扫描等项新技术,从而使其成为高接收灵敏度、多功能、通用性强、自动化程度高和操作简便的仪器。 在安装调试超声料位仪的工作中,现在和过去的对比十分明显。在七十年代一个高水平的技术员需几天时间才能完成这项安装调试工作,他有时得蹲在工作环境十分恶劣的槽罐内;有时得趴在地上一边仔细观察示波器屏幕一边不断地调节数个电位器以完成校准工作。但现在一个普通技术工人只需化30分钟就能做好同样工作。这种简化应归功于微机和其他新技术的应用。
In recent years, foreign ultrasonic level measurement technology has developed rapidly, a new generation of ultrasonic level meter equipped with microcomputer, and used to determine the receiving data, automatic sound velocity compensation, multiplexing and electronic scanning and other new technologies, so that It becomes a high acceptance sensitivity, versatile, versatile, highly automated and easy to operate instrument. In the installation of ultrasonic level gauge debugging work, the contrast now and in the past is very obvious. In the seventies a high-level technician took a few days to complete the installation and commissioning work, he sometimes had to squat in a very bad tank environment; sometimes have to lie on the ground while carefully observing the oscilloscope screen while constantly adjusting the number A potentiometer to complete the calibration work. But now an average skilled worker can do the same job in just 30 minutes. This simplification should be attributed to the use of microcomputers and other new technologies.
