Paper Abstract

While filling a container like rectangular cavity with a fluid, the level of the fluid raises with time depending upon the rate of fluid flow. The pressure at various coordinates could be estimated by solving the analytical equations involving the density and other properties of the fluid with the boundary conditions. The verification of the results can be made by comparing with the numerical results obtained and by experimental set up, if available. This paper presents the analytical equations for pressure while filling a rectangular cavitiy and proposes an opto-electronic pressure sensor for experimental verification of the results. The proposed pressure sensor employs a metallic flexible circular shaped diaphragm incorporating an opto-electronic coupling by means of a silver coated mirror attached to the diaphragm which in turn would deflect a laser beam continuously on a photo sensitive mosaic. Dynamic variation in pressure causes variations in deformations in the surface of the diaphragm elastically, and hence varies the angle of the mirror resulting in a variation angle of the deflected beam on the photo mosaic. With this variation in angle, the exerting pressure acting on the diaphragm is computed.
