A magnetic levitation conveying system conveys products on trays and measures the weight of the product without requiring removal of the product or tray. A track below the trays has magnetic levitation coils that generate a magnetic field when energized. The trays include magnets or other levitation elements that interact with the magnetic levitation coils to generate a propulsive levitating force on the tray. A sensor measures a parameter in the system to correlate the parameter with the weight of the conveyed product. The parameter can be a floating height of the tray above the track, an amount of energy necessary to maintain a particular floating height of the tray above the track, a force resulting from accelerating or decelerating the tray, a force required to maintain a desired curve radius when the tray moves around a curve, a force that counteracts an acceleration caused by an incline or other suitable indicator of weight.

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.

A flow rate measurement device improves the flow rate measurement accuracy without increasing the size of the metering tank. The flow rate measurement device includes a metering tank having a supply port at its upper portion and a discharge port at its lower portion, an on-off valve that opens and closes a flow channel inside the metering tank, a weight measurement unit that measures a weight of the metering tank, and flow rate computing unit that supplies powders and/or grains continuously from the supply port to the metering tank, computes a flow rate of the powders and/or grains multiple times in a temporally-overlapped state on the basis of the weight of the metering tank measured by the weight measurement unit in a state where the on-off valve is closed, and computes an average flow rate of the powders and/or grains on the basis of the flow rate computed multiple times.

A construction machine, which is a feeder vehicle or a road finisher, comprises an operating platform, a material hopper, a conveyor belt system and an electronic control system. The conveyor belt system comprises a conveyor belt and one or more weight sensors which are configured to measure weight force of paving material located on the conveyor belt. In addition, the conveyor belt system comprises one or more inclination sensors which are configured to measure an inclination angle and/or a roll angle of the conveyor belt system. The electronic control system is configured to receive and process data from the one or more weight sensors and the one or more inclination sensors to calculate a mass of the paving material.
