BT590178 Series Streamer Instruction Manual
1 Overview
The flow meter, also known as flow sight glass, flow indicator, and fluid indicator, can indicate the current instantaneous flow rate. It is suitable for industrial production pipelines such as petroleum, chemical industry, chemical fiber, medicine, food, power plants, pumps, and metallurgical equipment. It can be used at any time Observing the flow reaction of liquids, gases, steam and other media is one of the indispensable pipeline accessories to ensure normal production and product quality.
2. Working principle
The sight flow device consists of sight glass, nozzle, flap, dial, etc. The process connection can be in the form of threads, flanges, clamps, etc. The flow meter can measure the flow of liquid, gas, and steam. The flap rotates at different angles with the flow of the pipeline. The angle of rotation of the flap is proportional to the flow. The scale flow corresponding to the flap is the actual current flow of the pipeline. flow. The rotating plate flowmeter can only measure flow in a single direction, but the flow measurement is not affected by the installation direction. Flow measurement accuracy ±5%

3. Maintenance and maintenance of glass windows
3.1. The glass window is used to observe the flow reaction of liquid, gas, steam and other media and should be kept clean and dust-free.
3.2. The sight glass is a wearable part, so be careful when installing the sight glass.
3.3. The temperature and pressure resistance of glass has certain limitations, which will depend on the actual situation. The following provide the national standard glass manufacturing process physical experimental parameters: Temperature resistance: tempered borosilicate glass ≤ 200℃, quartz glass ≤ 1000℃, aluminosilicate glass ≤ 450℃ Pressure resistance: tempered borosilicate glass sheet ≤ 2.5MPa quartz glass sheet ≤ 10.0MPa Aluminosilicate glass ≤ 6.4MPa Ordinary glass ≤ 0.6MPa
3.4. The allowed sudden temperature change is < 60℃. The glass may break due to excessive temperature difference.
Glass testing standards: design, manufacture and acceptance with reference to the "Chemical Pipeline Manual" and HGJ501-502-86 "Pressure Window Sight Glass". 5. When repairing the sight glass, make sure that the fasteners, sight glass bottom plate, glass piece and sealing ring are free of debris before they can be installed evenly.
