ELESA original design 
EN 650.2 fluid level indicators are supplied with a protective housing made of zinc die-cast or plastic that allows them to be used in harsh operating conditions. The fluid level is visible from the side despite the protective housing.
The polyamide body consists of two parts, which are ultrasonically welded together. The fluid level indicators are individually tested for leakage at 3 bar air pressure.
These fluid level indicators can also be used on pressurized tanks. Tests regarding maximum pressure are available.
The reflector is a colorless anodized aluminum plate with black marking lines or temperature scale. The scale is located outside of the fluid, thus it is specially protected.
The fluid level indicators are supplied with the protective housing mounted.

The assembly of EN 650.2 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. |
