Fluid dispensing apparatus and method

A portable fluid dispensing apparatus for dispense of a fluid into a diluent and configured to be supported on an upper rim of a reservoir wall, the dispensing apparatus comprising:

• a housing;
• an inlet into which diluent is configured to flow into the housing;
• an outlet from which diluent is configured to exit the housing;
• a flow path extending through the housing along which diluent is configured to flow from the inlet to the outlet;
• a fluid reservoir within the housing, the fluid reservoir configured to support a chemical concentrate, and the fluid reservoir in fluid communication with a second flow path along which chemical concentrate is configured to be dispensed;
• and
• an attachment device defining a bearing surface oriented to contact and shaped to connect to the reservoir wall and to support the dispensing apparatus on the upper rim of the reservoir wall, the bearing surface positioned below the outlet,
• wherein a portion of the housing is disposed below the attachment device in an installed position of the dispensing apparatus on the reservoir wall,
• wherein dispense of diluent and chemical concentrate from the dispensing apparatus includes partially or fully mixed diluent and chemical concentrate, or unmixed diluent and chemical concentrate, and
• wherein the housing defines a portable unit configured to be selectively mountable on and removable from the reservoir wall via the attachment device.

• an attachment device defining a bearing surface oriented to contact and shaped to connect to the reservoir wall and to support the dispensing apparatus on the upper rim of the reservoir wall,
• a wheel located exterior of the housing and having a plurality of vanes, at least a portion of the wheel located within the first flow path and rotated by flow of diluent along the first flow path,
• wherein rotation of the wheel is configured to draw chemical concentrate from the fluid reservoir along the second flow path and to dispense chemical concentrate into the diluent flowing along the first flow path,
• wherein dispense of diluent and chemical concentrate from the dispensing apparatus includes partially or fully mixed diluent and chemical concentrate, or unmixed diluent and chemical concentrate, and
• wherein the housing defines a portable unit configured to be selectively mountable on and removable from the reservoir wall via the attachment device without the use of tools.
