一、前言玻璃转子流量计在流量测量中使用较广,它的特点是结构简单、价格便宜、压力损失小、测量范围宽、安装维护方便,改变转子材料后还可用于腐蚀性介质的测量,但它只能就地测量。由于无电信号输出,因而不能进行远传指示、记录、自动调节和累积。为此,我们经过两年多的努力,研制了GDL型光电远传玻璃转子流量计,实现了玻璃转子流量计信号的远传、指示、记录和自动调节。本仪器应用沈阳市玻璃仪器厂生 I. Introduction Glass rotameter is widely used in flow measurement. It is characterized by simple structure, low price, small pressure loss, wide measurement range, convenient installation and maintenance. It can also be used to measure corrosive media after changing the rotor material, But it can only be measured locally. Because there is no electric signal to output, therefore can not carry on the long-range instruction, record, adjust automatically and accumulate. To this end, after more than two years of hard work, we have developed a GDL-type photoelectric far-flow glass rotor flowmeter that enables remote transmission, indication, recording and automatic adjustment of glass rotor flowmeter signals. The instrument used glass factory in Shenyang Health
