Product description

Fluid level indicators EN 654.1 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.

These fluid level indicators are charactarized by their high chemical resistance and are therefore also suitable for media containing or based on glycol.

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