An apparatus for dispensing liquid from a container, and for monitoring the level of liquid within said container, comprises a container for storing liquid to be dispensed; and a conduit, the conduit comprising: a feed tube extending from the container to an appliance; a dip tube extending in the container to the bottom of the container; a liquid supply channel extending through the feed tube and dip tube and having an open first end defined by a lower end of the dip tube, which, in use, is arranged to be immersed in said liquid in said container, and a second end arranged, in use, to extend outside of said container; and a pressure measurement channel branching from the feed tube at a point located between said first and second ends of the liquid supply channel. The apparatus further comprises a pressure transducer in fluid communication with said pressure measurement channel, and a means to draw liquid from the first end of the liquid supply channel to dispense liquid from the second end of the liquid supply channel. The pressure measurement channel branches from the feed tube at a fixed height relative to the bottom of the dip tube.

System and method for distributing and dispensing liquids
The invention relates to a system for distributing and dispensing liquids, the system comprising a plurality of re-usable containers, each container comprising a removable closure arranged to engage with a neck of the container, the closure comprising a liquid flow passage extending through the closure; and a dip tube fluidly connected to or forming the liquid flow passage of the closure and extending into the container. The system further comprises a dispensing assembly comprising a dispensing pump, a dispensing tube fluidly connected to the dispensing pump, and a connector arranged to releasably engage with the closure so as to fluidly connect the dispensing tube to the liquid flow passage of the closure. The removable closure is a tamper-proof or tamper-evident closure, arranged to deter or prevent removal of the closure by an unauthorised person. A method for distributing and dispensing liquids using the inventive system is further provided. A further aspect relates to a hand-held displacement pump for use with the system and method of the present invention.

The invention provides a chemical dosing system (1) for adding a chemical concentrate (3) to a diluent (5), the system comprising: a container (4) for holding a diluent (5) and receiving the chemical concentrate (3); a dispenser mechanism (7) for dispensing a known quantity of concentrate (3) into the container (4); a detector (9) arranged to detect the quantity of diluent (5) in the container (4); and a processor (11) arranged to control the dispensing mechanism (7), so as to dispense a volume of concentrate (3) in dependence on the quantity of diluent (5) in the container (4). The invention aims to assist in achieving more accurate and easier dosing of chemical concentrates.
G01F 23/26 - Indicating or measuring liquid level or level of fluent solid material, e.g. indicating in terms of volume or indicating by means of an alarm by measuring physical variables, other than linear dimensions, pressure or weight, dependent on the level to be measured, e.g. by difference of heat transfer of steam or water by measuring variations of capacity or inductance of capacitors or inductors arising from the presence of liquid or fluent solid material in the electric or electromagnetic fields
G01F 11/28 - Apparatus requiring external operation adapted at each repeated and identical operation to measure and separate a predetermined volume of fluid or fluent solid material from a supply or container, without regard to weight, and to deliver it with stationary measuring chambers having constant volume during measurement
The invention provides a chemical dosing system (1) for an appliance (2), such as a laundry washing machine or a dishwashing machine, having a water inlet (16), the system comprising a meter (7) for determining the volume of water supplied to the appliance (2), a pump (20) for dispensing a quantity of a chemical to the appliance (2) and a control unit (19) arranged to receive a signal (26) from the meter (7) and to cause to be dispensed to the appliance (2) a volume of chemical that is proportional to the quantity of water supplied to the appliance. The invention may enable a correct quantity of chemical to be automatically dispensed to many types of appliance, without the need to know anything about the appliance, or to derive electrical signal from the appliance.
