Fluid Level Indicators EN 654

Product description

Information

Fluid level indicators EN 654 are very stable due to the aluminum U-rail and the cover, which makes them also suitable for long lengths. The fluid level can also be viewed from the side.

For special requirements of chemical, pressure, and temperature resistance, please contact us.

Assembly Instruction

The assembly of EN 654 fluid level indicators is very easy and economical. It is sufficient to drill two holes of Ø 10.5 or Ø 12.5 mm at distance l₁ in the container wall. The fluid level indicator can also be mounted directly, i.e. without nut, if the container wall is provided with the corresponding thread.

All component parts necessary for the assembly are included: hexagon nuts, O-rings, and serrated lock washers for securing. For a perfect seal, the screws should not be overtightened (max. 12 Nm). Recommended roughness of the sealing surface, Ra = 3 μm.
