    Abstract: A dispenser dispenses a consumable product from a container. The container is supported within a housing by a container holder. The container holder is vertically moveable within a movement range in the housing. A biasing structure biases the container holder upwardly. A sign is connected to move up and down with the container holder. An indicator associated with the sign is vertically fixed relative to the housing. When an amount of product remaining in the container reaches a low level, the biasing force of the biasing structure will lift the container holder, causing the indicator to be aligned with a portion of the sign that gives a visual cue to a user that the amount of product remaining is at a low level.

  • Publication number: 20120138628
    Abstract: Apparatus and related methods for continually measuring and dispensing precise amounts of bulk chemical in a car wash application. A gravimetric dispensing assembly can include a load cell and a syringe dosing pump that is suspended below the load cell such that an entire mass of the syringe dosing pump is communicated to the load cell. In this manner, the load cell can measure the actual mass of chemical being dispensed from the syringe dosing pump on a continuous basis without solely relying on the rated volumetric capacity of the syringe dosing pump. The syringe dosing pump can be driven by a stepper motor that can be pulsed as directed by a controller so as to maintain, increase or decrease an amount of bulk chemical being dispensed from the syringe dosing pump.

  • Patent number: 8028723
    Abstract: A receiving container is filled with a predetermined target mass mz of a free-flowing substance from a reservoir with the help of a dosage-dispensing device that dispenses measured doses of the substance. The device has a valve for variably setting the mass flow {dot over (m)} from the reservoir into the receiving container. The device is also able to determine the time t that has elapsed since the beginning of the fill cycle, the mass m of the substance present in the receiving container, and a unit for controlling the valve. The controller unit includes estimating and correction modules. At least once during the fill cycle, the estimating module performs an estimate of the mass {tilde over (m)}(t, t2) that is expected to be present in the receiving container at the end of the fill cycle at the time t2. This estimate is based on the assumptions that from the time t onward the valve is being closed according to a predefined closing-down profile and the fill cycle is completed at the time t2.
