Examples
- Contact level 10a 600v
触点级别10a 600v - Contact level 600v 10a
触点级别600v 10a - Manufacture and worldwide sales of non - contact level measurement , density measurement , weight measurement process control equipment
产品涉及视频领域音频领域广播测试系统数字电视领域等。 - Traditional contacting level measurement systems , such as the hydrostatic and capacitive systems , are simple and cheap , but the measurement is affected by the physical properties of the media in the tank and thus it is difficult to achieve high accuracy
高精度液位测量对各种液位自动控制系统的正常运行，对保证各种液体货物的安全储运以及对保证各种液体货物贸易的公平合理进行、避免国家财产的流失均有重要意义。 - Laser , ultrasonic beam and microwave are used in non contacting level measuring systems . laser systems suffer from dirt , ultrasonic sensors are strongly affected by changes of the velocity of sound and usually a pipe is needed to couple the ultrasonic waves into the liquid tank , which is difficult when there is a high pressure or when explosion protection is necessary
压力式液位测量系统原理简单、成本低，但测量精度和应用场合有一定的局限性，超声液位仪精度较高，但设备复杂，一般需要用导管将超声波传到被测的液体中，因而安装维护较麻烦，激光测距系统对环境要求严格。
