A dispenser system including a source of chemical concentrate, a source of diluent, and a mix chamber in fluid communication with the source of chemical concentrate via a first line and with the source of diluent via a second line to mix chemical concentrate and diluent to form a dilution. The dispenser system also includes one or more metering devices disposed in one or both of the first line and the second line, a discharge fluidly coupled to the mix chamber to deliver the dilution to a downstream receptacle, and a control system in communication with the one or more metering devices. The control system is programmed to adjust a concentration of chemical concentrate in the dilution via control of the one or more metering devices based on an environmental factor affecting a physical environment to be cleaned using the dilution.

Dilution adjustment system and method

The invention relates to a self-contained and wireless monitoring device () for use in a washing machine () to indicate shortage of detergent in said washing machine. The monitoring device comprises a sensor () arranged to monitor detergent concentration in washing liquid () of said washing machine and to provide an alarm signal (A) when said monitored detergent concentration is below a target value. The monitoring device is capable of floating in said washing liquid and comprises signalling means () for indicating said shortage of detergent in response to said alarm signal. The invention further relates to a package containing such a monitoring device and a method for indicating shortage of detergent.
