Abstract
An atmospheric tide and air density detector. The detector includes a chamber having an inlet and an outlet. A barometer is positioned within the chamber. An impeller, driven by a motor, is positioned in the outlet for drawing air from the chamber. An air flow restrictor is positioned in the inlet. A gauge is connected to the air flow restrictor for measuring the pressure exerted on the air flow restrictor by air drawn into the chamber during operation of the impeller.
