System for determining filling level in tank - forms sensor as flexible container linked to display in operators cabin by pipe and contg. liquid displaceable by weight of goods

摘要

The liquid medium in the sensor (44) is displaced to the indicating system (48) through the line (46), depending on the wt. of the goods bearing on the sensor. The indicating system is at least partly transparent and has a scale for different goods or is connected with such a scale. The medium is a coloured liquid and/or with a fluorescent substance. A float visible from the outside floats on the surface of the liquid. The liquid is frost proof. The float of the indicator cuts off the supply in its upper end position. ADVANTAGE - System can be produced at low cost and indication is delivered remote from tank. USE - Harvesting machine.
