Ultrasonic Liquid Level Indicator
-
摘要: 介绍利用单片机W77E58作为主控元件的超声波液位测量原理，给出设计方法和系统框图。该液位测量仪具有温度补偿，用标准反射杆作基准进行校正，可提高测量精度，且价格低廉，可靠性高。Abstract: The theory of ultrasonic liquid level testing was introduced. The design and the frame of the system with temperature compensation and the standard reflect as the basis for calibration were detailed, in which MCU W77E58 was used as the main control component. The measuring results showed that the system was low in price and high in reliability.
