ABSTRACT:
A flowmeter has a vertical flow tube with a float member therein and an electrically illuminatable display to provide a vertically graduated scale. The numeric scale indicia are preferably provided by a multiplicity of cell clusters, each comprised of one or more electrically illuminatable cells and the cell clusters are illuminated to show selected numerical scales that are chosen as a function of the specific gravity of a fluid and the pressure of the fluid being measured. The flowmeter includes a memory device containing stored information as to numeric values corresponding to various specific gravities and pressures to generate the appropriate scales and electrical signals corresponding thereto to illuminate the display.
