Abstract
Apparatus for sensing hydrostatic pressure in a fluid, forming a head for a bubble tube for immersion into the fluid. The head is formed of a plate having a flat lower surface for horizontal disposition within a liquid, a first orifice for introducing a gas under pressure from above the plate whereby the gas can form a bubble under the plate within the liquid. The effect of the plate is as a surface on which a stable sessile bubble of a variable size can be grown. This results in a bubble having a substantially increased radius of curvature at its interface, that is, the gas/liquid interface, on the underside of the bubble than previously obtainable. A pressure gauge measuring the gas pressure in the tube determines the pressure at the end of the tube within the fluid.
