Embodiment

[0104] Experiment content: Measuring the viscosity coefficient of irrigation water

[0105] This detection method is by using two different magnetic fields (one of these two magnetic fields comes from the permanent magnet in the magnetic ring 15, and the other comes from the excitation pulse generated by the electronic components in the sensor electronic chamber 14 along the waveguide made of magnetostrictive material in the sensor. The wire 17 runs at the speed of sound.) After the strain pulse signal generated when intersecting is captured by the sensing circuit of the sensor electronic warehouse 14, it is output in the form of an electrical signal, and the irrigation water with different viscosity coefficients encountered in the excitation pulse propagation, its corresponding The energy attenuation coefficient is different, and the different energy attenuation coefficients of irrigation water with different viscosity coefficients are measured, and the corresponding viscosity...

Abstract

The invention discloses a detection device and method for an irrigation water viscosity coefficient based on a magnetostrictive displacement sensor, and belong to the technical field of liquid viscosity coefficient detection. The detection device comprises a triangular iron support, a magnetostrictive displacement sensor, a temperature sensor, a measuring cylinder, a pressure sensor and a data processing and displaying device. The temperature sensor and the pressure sensor which are used for measuring temperature and density are arranged in the device, the influence of the temperature sensor and the pressure sensor on an experimental measurement result is considered, an experimental result is further corrected, and the accuracy is greatly improved. The limitation is greatly reduced, measurement can be carried out after a metal feeler lever of the magnetostrictive displacement sensor extends into the liquid for a certain depth, and the measurement can be carried out in any liquid and atany place as the condition is met. The magnetostrictive displacement sensor outputs continuous signals, and compared with a pulse signal, the signals are stable, the response speed is fast, the precision is high, the transportability is good and the data processing and display device can be easily connected.

Description

technical field [0001] The invention belongs to the technical field of detection of the viscosity coefficient of irrigation water, in particular to a detection device and method for the viscosity coefficient of irrigation water based on a magnetostrictive displacement sensor. Background technique [0002] The implementation of water-based charging in irrigation areas is conducive to promoting the scientific and rational use of water resources and improving the efficiency of agricultural water use. The research and development of scientific and practical water metering facilities is a key link in realizing the goal of water conservation in irrigation areas. In the research and development of water metering facilities in irrigation areas, when constructing mathematical models through numerical simulation software, it is necessary to accurately input the viscosity coefficient of irrigation water. This parameter is very important to ensure the accuracy of mathematical model calcu...
