Experiment on Capability of Agriculture Irrigation Water Computation Water Meter

Abstract:

In view of the influence of a certain amount of the sediment in agricultural irrigation water and low temperature to water meter accuracy, experiment of performance and abrasion under the different sediment rate and experiment of the freezing heaving in the different temperature to water meter were developed, the results show, the error rate of water meter is different under different sediment rate, and the error rate become bigger after abrasion 500h under the different sediment rate, and the reading of numerous water meter become smaller. Under the condition of low temperature, the water meter is easy to happen the frost heaving damage phenomenon when the water meter chamber filled with water, and the water meter is generally not heave when water meter chamber not filled with water. The change of water meter accuracy is little after low temperature frost heave.
