A monitoring device for monitoring crop yield is disclosed. The monitoring device is mounted to a housing of a grain elevator of an agricultural work machine proximate a crop conveyor assembly arranged in the housing and has at least one aperture formed therein. A material engagement member is arranged on the mounting structure and is pivotal with respect to the mounting structure about a pivot point. The material engagement member can comprise first end and a second end opposite of the first end. At least one rotational sensor is arranged in the monitoring device and is configured to detect spatial movement or position of the material engagement member. A processing device is coupled to the at least one rotational sensor and is configured to determine an aggregate crop yield based on the detected rotational magnitude of the displacement of the first end or second end.

Flow sensors, systems, and methods for continuous in situ monitoring of a rheologically complex fluid flow within a vessel, such as particulate and multiphase media for ascertaining certain fluid flow parameters, such as flow rate, dynamic viscosity, fluid density, fluid temperature, particle density and particle mass, from flow sensor measurements, the sensors, systems, and methods involving a fluid flow sensor having a body member with internalized strain gauges configured to measure the deformation of certain segments of the body member and, based, at least in part, on these deformation measurements, the system is used to compute the fluid flow parameters.

Apparatus, systems and methods are provided for monitoring yield while harvesting grain. Grain released from paddles on the clean grain elevator chain of a harvester contacts a flow sensor which reports the rate of grain flow through the clean grain elevator. In some embodiments a brush is mounted to the chain and disposed to clean the flow sensor surface. In other embodiments a bucket mounted to the clean grain elevator chain releases grain against the flow sensor at a rate dependent on a grain property.

A forage harvester gathers crop by a crop receiving assembly and delivers the crop via infeed units to aggregates for comminuting and conveyance. The crop is then conveyed to a transport vehicle via a discharge chute provided on a discharge tower. A device for adjusting the tilt angle of the discharge chute is provided for guiding the crop mass flow onto the transport vehicle. A method for measuring a crop mass flow on the forage harvester is based on sensing a force proportional to the crop mass flow, which acts upon the device for adjusting the tilt angle of the discharge chute, and calculating the crop mass flow in a computing unit based on the sensed force.
