Indicator tube: Borosilicate glass (Pyrex®)
U-rail: Aluminum, anodized, natural color
End pieces: Technopolymer plastic (Polyamide PA), matte black
screws: Stainless steel
O-ring: FKM rubber (Viton®)
Due to the U-rail and cover, Elesa®
design EN 654.1 fluid level indicators are extremely stable and therefore suitable for long lengths. The fluid level can also be viewed from the side.
These fluid level indicators have a high chemical resistance and are also suitable for media containing or based on glycol.
Temperature resistant to 212°F (100°C).
For special requirements of chemical, pressure,and temperature resistance, please contact us.
Other l1 lengths, temperature display, and electrical temperature monitoring available upon request.
||Installation of EN 654.1 oil level indicators is very simple and economical. You need to drill two Ø 10.5 or Ø 12.5 mm (depending upon "d" thread) holes in the container wall, l1 distance apart.
Oil level indicator can also be installed directly,
i.e. without nuts, if the container wall has a mounting thread.
All individual parts necessary for the assembly are provided, including
hex nuts, O-rings and serrated lock washers.
For a perfect seal using the O-rings, the screws should not be too
strongly tightened (max. 12 Nm). Recommended roughness of the sealing surface is RA = 3 μm.
