摘要

搭建了一个完整的校准试验台,研究了不同俯仰和滚转位置对微波固体型流量传感器测量误差的影响。结果表明,当斜槽俯仰(下降和上升)和滚转角位置在1.5°~ 4.5°范围内变化时,测量误差分别为2.50% ~ 6.82%和1.80% ~ 8.86%。在低螺旋输送机转速范围内,测量误差较大。然而,对于任何典型的湿水田地形,误差的幅度都在可接受的范围内。

Online Measuring Of Grain Flowrates and Its Measurement Sensitivities with Pitch and Roll Angles
A complete calibration test stand was constructed and instrumented to examine the effect of varying pitch and roll positions on the measurement errors of a microwave solid type flow sensor. Results indicated that measurement errors ranging from 2.50% to 6.82% and 1.80% to 8.86% were obtained by the changing of chute pitch (descending and ascending) and roll angle positions from 1.5° to 4.5°, respectively. Greater measurement errors were found at the low screw auger conveyor speed range. However, the magnitude of errors is within the acceptable margin for any typical wet paddy land topography.
