  • Page 9: Background - How It Works

    BACKGROUND – HOW IT WORKS The Well Watch 700 works by pushing an air pressure wave or low frequency sound wave into the well. For this reason, it is important that the probe be connected to a closed end of the pipe to prevent the air pressure from just escaping the open end.
  • Page 10 When set to 9ft, the depth would read 12. When set to 14ft, it would read 18 etc. In this case, it may be helpful to leave a small leak at the probe to help dissipate the pulse. Eno Scientific Well Watch 700 Page...
