This sight flow indicator is ideal for you to visually check the flow, presence, colour and condition of a liquid.
Features
- Screwed and flanged connections
- High visible PTFE spinner
- CE marked and fully PED compliant
- High temperature and pressure ratings
- Short lead times
- Designed and manufactured in the UK
Applications
With the highly visible PTFE spinner the style S sight flow indicator is used to check the flow of a liquid in a pipeline. It can be used in vertical or horizontal lines and is ideal for flow monitoring in full pipes.
Construction
The standard bodies are cast in either carbon steel or 316 stainless steel, though we can produce them in other materials.
The glass windows are held in place by stainless steel covers and screws, and sealed with PTFE gaskets, giving superior protection. For ease of maintenance, the glasses can be individually removed and replaced.
For standard applications, the indicator is fitted with toughened soda lime glass discs to BS3463 and rated to 16 bar.
For steam and condensate we recommend toughened borosilicate glass, while for alkaline liquids mica discs can be used to protect the glass.
The sight glasses can be supplied with screwed connections to NPT, BSP parallel or taper. The standard flanges available are ANSI 150, ANSI 300 and PN16, though other flanges can be supplied.
