A differential dosing scale and method for dosing liquid. An immersion container in which the liquid to be dosed is contained and/or can be received and/or out of which the liquid to be dosed can be discharged for the dosed removal of the liquid. An immersion tube is immersed into the immersion container for the dosed removal of the liquid to be dosed from the immersion container. A dosing via which the liquid to be dosed can be suctioned out of the immersion container via the immersion tube and can be discharged from the differential dosing scale. The differential dosing scale being designed structurally and/or in terms of control technology to maintain, in the immersion container, a liquid level of the liquid to be dosed at a constant predefined and/or predefinable level relative to the immersion tube.

A dispensing system is disclosed for dispensing material from multiple hoppers to a convey line. As disclosed, material is dispensed from the hoppers via operation of a variable rate feed device. The application discloses a controller device configured to utilize input from a first load cell for a first hopper and a second load cell for a second hopper to determine a mass flow rate to increase or decrease the feed rate so that the flow rate of material dispensed into the convey line matches a set mass flow rate of material. In the embodiments disclosed, the hoppers include hoppers connected in series to the convey line and hoppers connected in parallel to the convey line. The controller device determines the mass flow rate based upon input from one of the first or second load cells during a first time period and both the first and second loads cells during a second time period for different operating phases of the system.

The present invention provides a way to monitor using a weight sensor to a high degree of precision the rate of material consumption from a reservoir while in operation by alleviating perturbations due to extraneous forces exerted on the reservoir by the connecting tubes and conduits that carry the material and transmit electrical signals between the reservoir and the other components of the dispensing system.

A granule-dosing system for plastics processing machines including a weighing container removably retained in an operating position on a framework; a plurality of supply containers having outlets which are connected to an inlet of the weighing container via dosing mechanisms; a mixer with an inlet which is connected to an outlet of the weighing container; and a safety switch and a control device designed to switch off the dosing mechanisms and/or the mixer when the safety switch emits a switch-off signal, wherein the weighing container is configured such that, in the operating position, it blocks access to the dosing mechanisms and/or to the inlet of the mixer, and the safety switch is arranged on the framework such that it emits the switch-off signal when the weighing container is removed from the operating position.

An addition system for introducing particulate material into an industrial process is disclosed. The addition system comprises a vessel for holding the particulate material, a weighing device, piping, a controller, and a frame to support the piping. The piping comprises a first valve for transferring the particulate material to the industrial process, and a second valve for transferring a first stream of pressurized gas from a source of pressurized gas to the vessel. The vessel comprises a quick-release hatch located on the top of the vessel.
