An instrument consisting essentially of a vertical tube inserted into a water-main, to show the pressure of the fluid at that point, by the height to which it ascends in the tube of the piezometer.

A sounding-apparatus in which advantage is taken of the compression of air in a tube by the pressure of the water at great depths to indicate the depth of the water.

An instrument for testing the pressure of gas in the bore of a gun.

An instrument for measuring the compressibility of liquids.

A gauge connected with a water main to show the pressure at that point.
