ELESA original design 
A special feature of EN 650.1 fluid level indicators is that the fluid level is visible even from the side.
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 white lacquered aluminum plate with black marking lines or temperature scale. The scale is located outside of the fluid, thus it is specially protected.
The design of the fluid level indicators offers a magnifying effect that makes the scale easily legible.

The assembly of EN 650.1 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. |
