摘要: A well depth measuring device that collects data so operators do not have to manually record the in field and then again into a computer. The is attached head. rotary encoder rotates as probe/sensor lowered via longitudinal strip of tape. sends pulses electrical circuitry handheld computer stores information. stored information can be easily transferred other computers databases.
