步进电机驱动的高精度液位智能测量仪

A Step Motor Driven High Precision Intelligent Apparatus for Measuring Liquid Level

本文首次推出用步进电机驱动的钢绳浮子式液位测量仪。它由罐顶测量仪、脉冲电源、STD工业计算机及多路转换器组成。特点是罐顶测量仪的机械结构和电路都很简单,测量精度高,几乎不受环境温度变化的影响,价格较低,操作方便。容易维护,可用于罐群液位远距离的巡回测量,也可与集中管理系统的上位计算机联网,直接调用数据。

This paper for the first time presents the steel rope —float type apparatus for measuring liquid level. It is composed of a top tank gage, a pulsed power source, an industrial STD computer and a multiplexer. The characteristics of the apparatus are: it is simple in mechanical structure and circuits; its precision is high and it will almost not be affected by environmental temperature variation. Besides, it is cheap and easy to maintain and operate. It can be used in automatic long distance tour inspection.
