Abstract: Arrangement for the regulation of the height of a liquid level, such arrangement being particularly suitable for the removal of condensate from the regeneration heaters of steam turbines. The arrangement includes a transmitter nozzle for forming a gas-liquid mixture in a first, influx chamber communicating with a tank containing the liquid, a second chamber connected with the influx chamber and containing a two-phase outlet sensor which separates the gas in the gas-liquid mixture, and a system for discharging liquid from the tank including a discharge valve controlled by the pressure of the liquid in the second chamber.

Abstract: Arrangement for sucking-off gases, creating by means of water supplied to an annular nozzle surrounding the outlet of a gas conduit and forming a first hydraulic pump with a vortex, thereby mixing the gas and water thoroughly and sucking off the mixture by a second annular water nozzle into an ejector or second pump extending into a diffuser which terminates below the level of water in a vessel, where separation of the gas and water takes place.

Abstract: There is disclosed a circuit arrangement for regulating the level of a liquid in vessels. The arrangement according to this invention comprises a draining vessel with a draining conduit, a fluid level pick-up device, a compensation pick-up device, and a working element. The main feature of the circuit arrangement is that the compensation pick-up device is connected to the draining vessel above the regulated liquid level and the upper part of the fluid level pick-up device is also connected to the draining conduit above the regulated liquid level. The lower part of the fluid level pick-up device is connected below the regulated level equally to the draining conduit.
