摘要
首先介绍了应用超声技术来测量液位的基本原因,然后详细描述了一种适用于加油站油罐油位的自校准超声液位测量仪.文中还介绍了现场标定的方法.
The main reason of using ultrasonic technology to measure the liquid level is introduced firstly. Then a kind of self-calibrated ultrasonic level meter adapted in petrol stations for oil level measurement of oil tanks is described in detail. The method of field calibration is also introduced.
