A multi-component fluid delivery system includes a first fluid pump and a second fluid pump. The first and the second fluid pumps are not mechanically coupled to each other. The multi-component fluid delivery system further includes a control system comprising a processor configured to derive a slip ratio for the first fluid pump and the second fluid pump. The processor is additionally configured to apply a master-slave motor control to deliver a specified fluid ratio via the first and the second fluid pumps based on the slip ratio.

A fluid delivery system includes a first pressure sensor disposed on or near a spray gun and configured to monitor a first fluid, and a second pressure sensor disposed on or near the spray gun and configured to monitor a second fluid. The fluid delivery system further includes control system comprising a processor configured to receive a first signal from the first pressure sensor and to receive a second signal from the second pressure sensor. The processor is further configured to derive a pressure difference between the first and the second pressure sensor representative of a fluid pressure difference between the first fluid and the second fluid and to control one or more pumps to obtain a desired pressure difference.

The present invention relates to the application of liquid active substances. The subject matter of the present invention is a system, a method and a computer program product for the application of an active substance concentrate from a replaceable cartridge in a diluted form onto a target object with the aid of a portable spray device, wherein important parameters of the spray process are exchanged between the cartridge and/or the spray device and/or an external computer system.

The invention relates to the application of liquid active substances with the acid of a portable spray device. The subject matter of the present invention is a system comprising a portable spray device and a replaceable cartridge that contains an active substance concentrate. The invention also relates to method for applying a liquid active substance formulation. In addition, the invention discloses a replaceable cartridge that has a memory unit in which information is stored relating to an adjustable dilution ratio for the active substance concentrate contained in the cartridge. The invention also relates to a spray device comprising a control unit that can be read out a memory unit of cartridge attached to the spray device and, on the basis of the read out information, adjust a dilution ratio for the active substance concentrate contained in the cartridge.

The present foam dispensing unit comprises a manifold defining a first channel and a second channel. The first channel defines an input for receiving a first liquid and an output for directing the first liquid into a mixing nozzle. The second channel defines an input for receiving a second liquid, and an output for directing the second liquid into the mixing nozzle. The foam dispensing unit further comprises a first flow adjustment mechanism positioned along the first channel for controlling a flow of the first liquid at the output of the first channel, and a second flow adjustment mechanism positioned along the second channel for controlling a flow of the second liquid at the output of the second channel.
