How to select a sight glass?
Marine sight glass is a kind of instrument for observing and measuring the liquid flow state, which is mainly used in ship pipelines and valves. When choosing a marine liquid flow viewer, first of all, we should clarify the requirements, such as the type of liquid to be observed, flow range, installation location and so on. Secondly, the precision and stability of the product should be considered, the higher the precision the better the stability. In addition, the appearance, size, weight, price and after-sales service of the product also need to be considered to facilitate the subsequent stable use.
Overview
Size and connection:
Select the appropriate size to match the specifications of the pipe or tank.
Common connection methods include flanged and threaded connections, which should be selected with ease of installation and sealing in mind.
Pressure and temperature ratings:
Ensure that the observer can withstand the maximum operating pressure and temperature in the system.
Check the pressure and temperature ratings provided by the manufacturer and select a model that meets or exceeds the system requirements.
Maintenance and replacement:
Consider the ease of maintenance and cleanliness of the observer and select a model with a simple design and easy disassembly.
Select a viewer with replaceable parts to facilitate maintenance and replacement when needed.
Other special requirements:
If the application is in a flammable or explosive environment, select a observer that meets explosion-proof standards.
For particularly corrosive liquids, select a model with a special anti-corrosion coating.
