发明名称 Groundwater azimuth detection
摘要 An apparatus detects the azimuth of the migration of groundwater containing suspended microscopic particles. The apparatus comprises a probe consisting of a light source which emits light in a vertical orientation and a photodigitizer which faces the light source and is separated from the light source to permit the flow of groundwater between the light source and the photodigitizer. When the probe is submerged in migrating groundwater, the eclipses of light created by the suspended microscopic particles as the groundwater passes between the light source and the photodigitizer are detected by the photodigitizer. Information from the photodigitizer is processed and then visually displayed.
