资料介绍

射流电子水表因其检测到的是模拟低频小信号,其信号常被噪声电频所淹没,以至于无法正常测量流体信息。本文从射流电子水表计量原理出发,设计信号采集处理电路,并结合单片机技术,设计出一种高精度的小口径射流电子水表。该射流电子水表具有结构简单,计量精确等特点,同时在水质质量差的条件下也能测量,并具有不结垢、不堵塞、自清洁等特点。

The signal detected by Fluidic Oscillator type electronic water meter is simulated low frequency small signal, often overwhelmed with noise level, so it is difficult to measure the fluid information normally. Based on Fluidic Oscillator type electronic water meter measurement principle, this paper adopt the signal collection and processing circuit, combined with microcomputer technology, design a kind of high precision small Fluidic Oscillator type electronic water meter. The Fluidic Oscillator type electronic water meter has simple structure, precise measurement, at the same time can measure under the condition of the poor quality of the water, it also has the characteristic of no scaling, no jams, self-cleaning, etc.
