  • Fluid Dispenser With Sensor for Determining the Volume of Fluid in a Collapsible Container
    Publication number: 20220240729
    Abstract: A method of determining the volume of fluid contained in a collapsible bottle, the collapsible bottle containing a fluid to be dispensed from a fluid dispenser. The fluid dispenser has a distance measuring sensor, and the collapsible bottle is coupled to the fluid dispenser so that a preselected surface of the collapsible bottle is positioned in a measurement path of the sensor. The fluid dispenser is activated to dispense an allotment of the fluid from the collapsible bottle, the collapsible bottle collapsing in a predictable manner as the fluid is dispensed from the collapsible bottle. The sensor is used to measure a distance between the sensor and the preselected surface of the collapsible bottle, the distance changing predictably as the collapsible bottle collapses. The volume of the fluid contained in the collapsible bottle is determined based on the distance between the sensor and the preselected surface of the collapsible bottle.

  • Fluid level gauge
    Patent number: 9027788
    Abstract: A fluid level gauging mechanism external of a reservoir bottle in a dispenser which mechanism emits electromagnetic radiation and senses the electromagnetic radiation emitted which passes through the bottle or is reflected from the bottle through a wall of the bottle into the bottle at a first height and senses reflected radiation passing outwardly from the bottle at a second different height.
