Study Of The Immerging Water Level Measure System

This project stem is committed by Hefei SanLi automatic engineering co,. Ltd, aiming at developing a set of microprocessor based water-level measuring system to meet the requirement of market.The equipment of water level measuring plays an important role in the hydrology of all sorts of rivers. This water-level measuring system is a kind of intellectual in-field measuring system with the function of real time measuring being provided. And also, it can gather the water-level messages of different site transmitted by its communication interface to the staff of water-level supervision for their analysis.The theory of this measuring system is to utilize the piezoresistive transducer for the sensing of variety of water level and then the micro-voltage signal is converted by the A/D chip and processed by microprocessor. This water-level measuring system has high precisian, and is a kind of intelligent and compacted system, it obeys the design principle of intelligent instrumented, it takes the proponents solving proposal of the present-day instrumental design. Therefore, its circuitry works safely, its configuration is simple, its power consumption is low. With the combination of the measuring technology and the computer technology combined by the arithmetic of embedded instrumental software, the function of this measuring system are dike that zero self-regulation, self-calibration, software filtering, and etc. This water-level measuring system has good real-time performance of is-field measuring, it can automotive amend the errors resulted from the variety of air pressure, water temperature, sand capacity and other factors, while with the high reliability of communication and wide applicability, the performance of this measuring system is compatible with the domestic and overseas congener products.
