The top-mounted tank indicator is a mechanically operated, on-the-spot indicator. The liquid level in the tank located below the indicator is determined proportionately to the filling level and is indicated. Control of the level is easily achieved through the installation of switching contacts. The switching points for level control can be steplessly adjusted, on-the-spot and at any time.
