概述本文介绍一种精密数字液位计,它的主要特点是:(1)能鉴别液面的微小变化,用数字直接显示出液面上升与下降的高度,显示的最低数位为0.1毫米,因此能自动测定液位的涨落变化情况;(2)可任意设定、显示数字的测量起始点,因此不仅能测量河流、水库的水 Overview This article describes a precision digital level gauge, its main features are: (1) to identify minor changes in the liquid level, digital directly shows the liquid level rise and fall height, the lowest digit of 0.1 mm display, therefore Can automatically determine the fluctuation of the liquid level; (2) Can set and display the starting point of the measurement of the number arbitrarily, so not only the water of the river and the reservoir can be measured
