Design for Intelligent Numeralization Matter Level Instrument for Big Bulk

介绍了智能数字化大仓物位仪的原理和设计方案。讨论了采取怎样的措施抑制温度的影响以及噪声和干扰的影响；怎样利用微机提高测量精度。从而保证在１２．５ｍ的测量高度内，最大测量误差不大于±０．０２ｍ。

The principle and disign are introduced for intelligent numeralization matter level instru-ment for big bulk.The control method are discussed for the influence on temperature,noise and dis-turbs.Then the how to optimize the sensitivity that the maximal error is not exceeded±0.02 metre in12.5 metre measuring range is described.
