Abstract

The desired liq. level detector has a water-jet pump connected in the liquid supply line. A level indicator (7) is connected to the suction side of the pump (4). At least one vent pipe lying with its free mouth opening at the desired level is connected to the pump suction side, so that when the desired level is reached the mouth is closed by the inflowing liquid. The mouth of the supply line may lie lower than the vent pipe mouth which determines the desired level.
