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 required-circulated-refrigerant flow-rate calculating portion provided in a chilled-water flow-rate estimation calculation portion calculates an evaporator exchanged heat quantity exchanged between a refrigerant and chilled water at an evaporator based on a planned chilled-water-flow-rate value and a measured value of the temperature of the chilled water flowing in the evaporator, and calculates an evaporator-refrigerant flow rate based on that evaporator exchanged heat quantity. Then, a circulated-chilled-water flow-rate back-calculating portion back-calculates an evaporator-refrigerant flow rate based on the calculated evaporator-refrigerant flow rate and a ratio between a set value of differential pressure between a condenser and the evaporator and a measured value of that differential pressure, back-calculates an evaporator exchanged heat quantity exchanged between the refrigerant and the chilled water at the evaporator from the back-calculated evaporator-refrigerant flow rate, and back-calculates the flow rate of the chilled water.

Disclosed are utilitarian and ornamental features of fluid flow meter housing technologies. Such housing technologies comprises removable covers where such covers are associated with the meter housings without using bolts to better distribute pressure across the surfaces of the flow measurement components inside the meter. Such configuration reduces measurement component deformation over time. Further disclosed are damping elements configured to reduce noise from the measurement elements disposed inside a fluid flow meter.
