A weighing apparatus includes a conveyance unit configured to convey an article, a weighing unit configured to weigh weight of the article conveyed by the conveyance unit, a processing unit configured to process an original signal related to weighing, by a plurality of digital filters set in advance, the original signal being output from the weighing unit, and a display unit configured to display information output from processing unit, in which the processing unit is configured to generate evaluation information for each digital filter to be applied, based on a result of sequentially applying the plurality of digital filters to the original signal that is output when the conveyance unit is in operation and the article is not conveyed by the conveyance unit, and the display unit is configured to display at least one of the evaluation information.

Provided is a weighing apparatus with a flowmeter function includes a load sensor unit configured to detect a load of a flow rate calculation target, an A/D conversion unit configured to sequentially convert load signals from the load sensor unit into digital load data at predetermined intervals, an arithmetic processing unit configured to sequentially convert the load data into weighed values to calculate flow rate values, and a storage unit for storing the weighed values. The arithmetic processing unit calculates change amounts in weighed values and calculates a flow rate value based on a flow rate calculation cycle set based on a minimum time by which the change amounts become equal to or more than a change amount in weighed value, the change amount being calculated based on a minimum indication of weighed value and the required resolution of weighed value and satisfying a required resolution.

Checkweigher system embodiments and associated weigh-in-motion methods that are usable to produce increased object weigh time and improved weight determination accuracy without a decrease in object throughput. Generally speaking, exemplary methods initiate weight data collection earlier than, and terminate weight data collection later than, known methods. An exemplary method may also make use of derived mean error data associated with object weight measurements at various locations along a checkweigher to determine if an object weight measured over less than a desired weigh time is nonetheless acceptable.

An assembly for processing fruit and vegetable products includes a plurality of units for containing fruit and vegetable products (A), which can move in sequence along a conveyance line. The assembly includes at least one vision element, arranged along the line and intended at least to check the actual number (N) of containment units on which each product (A) lies and is conveyed along the line, with such actual number (N) being able to depend randomly or otherwise on the size, shape, arrangement and/or method of loading on the line of the respective product (A). Downstream of the element there are at least one first device for weighing a first predefined number (n.sub.1) of consecutive containment units and at least one second device for weighing a second predefined number (n.sub.2) of consecutive containment units.
