A weighing apparatus includes a rough-charge weigher and a combination weigher. A plurality of weighing hoppers of the combination weigher are, when seen in a plan view, arranged in a manner to form a line that constitutes a part of a virtual circle. The plurality of weighing hoppers include a one-end weighing hopper disposed at one end of the line, an other-end weighing hopper disposed at the other end of the line, and a plurality of middle weighing hoppers arranged on the line between the one-end weighing hopper and the other-end weighing hopper. The rough-charge weigher is, when seen from the one-end weighing hopper and the other-end weighing hopper, disposed at an opposite side to the middle weighing hoppers, and at least a part of the rough-charge weigher is disposed inside the virtual circle or on the virtual circle.

The invention relates to a method for dosing a target component (20), wherein a dosing system (10) doses the target component (20) to a target value (Z20), which corresponds to a desired nominal value (S20soll), wherein an additional dosing system (12) doses at least one additional component (21, 22, 23) to be follow-on dosed, to a target value (Z21) of the component (21, 22, 23) to be follow-on dosed which is lower than a desired nominal value (S21soll) of the component (21, 22, 23) to be follow-on dosed, wherein an actual value (G20ist) of the target component (20) and at least one actual value (G21ist) of the component (21, 22, 23) to be follow-on dosed are then determined, a content (A) of the target component (20) then being calculated according to the actual value (G20ist) of the target component (20) and/or the actual value (G21ist) of the component (21, 22, 23) to be follow-on dosed and the content (A) being compared to a limit value (T) or tolerance band (T), at least the component (21, 22, 23) to be follow-on dosed being additionally dosed in the event of the limit value (T) or tolerance band (T) being exceeded.

A weighing apparatus includes a rough-charge weigher and a combination weigher. The rough-charge weigher includes: a feeding device; a lower hopper configured to hold and discharge objects to be weighed that are fed from the feeding device; a feeding adjuster configured to feed the objects to be weighed from the feeding device to the lower hopper, and adjust an amount of the objects to be weighed that are fed to the lower hopper; and a weight sensor provided on either the feeding device or the lower hopper. A controller: continuously measures, by the weight sensor, a weight of the objects to be weighed that are fed by the feeding adjuster from the feeding device to the lower hopper; and at a point when the weight of the objects to be weighed that are fed to the lower hopper has reached the rough-charge weight, stops the feeding adjuster.

An exemplary dispenser includes a housing and a refill unit. The refill unit being removable and replaceable. The dispenser also includes a processor, memory, a dose count stored in memory that is indicative of the number of doses in a full refill unit, a level sensor for detecting a predetermined level the refill unit and a dispense count indicative of the number doses of product dispensed from the refill unit. In addition, the dispenser includes memory and has logic stored in the memory for recalibrating the number of doses remaining in the refill unit as a function of the dose count, the number of doses of product dispensed and the predetermined level of product. The number of doses of product remaining in the refill unit may be displayed on the dispenser, on a remote station, or on both the dispenser and a remote station.

An opening portion (34) that is formed so as to pass-through an opening/closing plate portion (32) of a gate (30), can be disposed at a region overlapping a lower end opening (24A) of a hopper (20). The opening portion (34) is structured by a first pass-through portion (34A), and a second pass-through portion (34B) that is formed so as to be continuous with the first pass-through portion (34A). A width, in a direction orthogonal to a lined-up direction in which the first pass-through portion (34A) and the second pass-through portion (34B) are lined up, is narrower than the first pass-through portion (34A). Further, a driving mechanism (40) moves the gate (30) such that the opening/closing plate portion (32) moves in the lined-up direction as seen in a plan view. Based on a preset target value of weight of sand, a control section (18) controls the driving mechanism (40) so as to decrease an amount of overlap of the opening portion (34) of the gate (30) and the lower end opening (24A) of the hopper (20) in a stepwise manner in accordance with an increase in the weight of the sand measured by a scale.

A system of detecting loading and unloading of mobile containers such as grain carts utilizes two low pass filters to determine whether the contents of the container are changing by subtracting one filter signal from the other, and using the sign of the difference. Weighing performance is improved by utilizing accelerometers to compensate for measurement dynamics and non-level orientation. Failure and degradation of weight sensors is detected by testing sensor half bridges. Loading and unloading weights can be tied to specific vehicles by utilizing RF beacons.
