一种光电式水表的设计方法

A Design of Photoelectric Watermeter

目前的电子式水表大多采用磁感应元件进行基础采样,这种水表由于采样处容易受到磁干扰,电子计量和机械计量存在误差。有些改进的设计使用光电直读水表,由于结构复杂,所需光电元件较多,故障率较高。探讨一种新的光电式水表的设计,从而改进上述两种设计的不足。

Most of the electronic water meters use magnetic induction elements for basic sampling.This kind of water meter is susceptible to magnetic interference at the sampling site, and there are errors in electronic and mechanical measurement. Some improved designs use photoelectric direct reading water meter. Because of its complex structure, more photoelectric components are needed and the failure rate is high. This paper discusses the design of a new photoelectric water meter, so as to improve the shortcomings of the above two designs.
