在现场总线技术的广阔天地里，共鸣着200个故事：选择玻璃转子流量计的智慧之歌

一、玻璃转子流量计的品种及选用

glass flow meter, according to its use and adaptability, can be divided into eight series: ordinary type, reinforced type, small flow rate and small exterior type, corrosion-resistant type, laboratory type, insulation type, alarm type and high-pressure resistant type. The maximum diameter of the glass tube is 100mm. The measured flow range is from 0.1ml/s to 40m³/h for liquids (water) and from 1ml/s to 1000m³/h for gases (air).

二、玻璃转子流量计的刻度修正

The calibration of a glass tube flow meter is based on the principle that when a liquid flows through the tube at a constant pressure difference between its ends, the volume of fluid flowing per unit time will be proportional to the square root of this pressure difference.

三、如何使用现场从流量计刻度读数求取实际流量值？

To obtain an accurate measurement in practice requires careful consideration of factors such as temperature variations in both gas properties and air density changes with altitude.

四、用户根据实际使用流量，如何选购合适的转子流量计？

When selecting a suitable glass tube flow meter for practical use conditions involving specific measurements or higher accuracy requirements than those provided by standard meters available on market shelves.

五、结语：

In conclusion,

Glass tube flow meters offer simplicity in design while maintaining precision.

Their versatility allows them to measure various fluids.

They are easy to read but require proper calibration considering variables like temperature change affecting gas properties & air density variation due to altitude differences during usage under real-world conditions.

Glass tubes are used because they provide stable readings over long periods without needing frequent cleaning; however their sensitivity makes them prone towards contamination which could lead potential errors if not cleaned properly before each test run; therefore proper care must always be taken during handling these instruments while working within environmental protection equipment systems where precise measurements matter most especially when it comes down measuring gas emissions accurately since slight deviations could mislead decisions leading potentially hazardous consequences.
