Abstract: A method as well as a liquid mixing system for providing a liquid mixture of water with at least one additive. The liquid mixing system comprises a first water reservoir, a first additive reservoir, a mixing unit, a conveying device and a line network. At least one first measurement value of the flow of the first additive conveyed to a mixing device is determined by an additive flowmeter. The total stream of the liquid mixture conveyed by the conveying device is measured by a liquid mixture flowmeter. The determined measurement values are transmitted to a control device, and from there passed on to a data storage device where they are stored.

Abstract: A lance, in particular for jointly dispensing a pressurized fluid and an additive for penetrating walls, includes a lance body, a handle arrangement, multiple channels and actuator arrangements interacting therewith, a nozzle arrangement as well as at least one container for the additive. The actuator arrangements selectively control the fluid being conducted in the first channel, the additive being conducted in the second channel, and the ambient air being conducted in the third channel to a first nozzle body. The third channel forms a line connection between the ambient air and a mixing chamber of the first nozzle body. The second actuator arrangement with its second actuator directly acts on the third channel and indirectly controls the admixing of the additive via the second channel into the mixing chamber.
