NSTALLATION
Level meter is installed into the upper lid of the tank (vessel), using a fi xing nut or a fl ange.
If installed in an open channel (sumps, reservoirs, etc.), install the level meter as closest as you can to the maximum level
expected.
The front of the level meter must be vertically to the measured level.
Foam on the level absorbs the acoustic wave refl ection which might cause malfunction of the level meter. If possible select the
location where the foaming is as low as possible.
Protect the level meter against direct sunlight.
In the case of uncertainty we recommend to consult the application with the producer.
