一、概述容积式流量计机械计数所采用的传统计数器在4个方面存在不足:一是体积庞大;二是制作成本高;三是没有互换性;四是计量准确度不够。本文要解析的这种新型计数器,自身的设置可以调节出的转数比能覆盖流量计腔体容积从0~100%的任何一个容积点。转数比的点和点之间的间隔平均在万分之六左右,即平均准确度为万分之三。该计数器 First, an overview of the volumetric flowmeter mechanical counter using traditional countermeasures in four aspects: First, bulky; Second, high production costs; Third, there is no interchangeability; Fourth, the measurement accuracy is not enough. This new type of counter to be analyzed in this paper can be adjusted by its own settings to cover the capacity of the flowmeter cavity volume from 0 to 100% of any volume point. The interval between points and points of rotation ratio is on the average of about six ten thousandths, that is, the average accuracy is three ten thousandths. The counter
