Abstract
A gauge means according to the present invention comprises a gauge face and indicator means disposed adjacent the face, at least a part of the indicator means extending along the face in a first direction, and at least a part of the indicator means being movable along the face in a second direction generally transverse to the first. A first scale comprises a first series of indicia marks progressing longitudinally along the extending part of the indicator. Each mark of the first series corresponds to a given value of a first parameter. A second scale comprises a second series of indicia lines each of which extends along the face angularly with respect to the first and second directions. Each line of the second series corresponds to a given value of a second parameter. The movement of the movable part of the indicator means is responsive to a third parameter. The first, second, and third parameters are functionally related. The gauge means may be associated with a fluid handling apparatus containing a fluid having a fluid head. One of the first two parameters is a function of the density of the fluid and the other is a function of the fluid head. The third parameter is the pressure of the fluid, and the movable part of the indicator means is operably exposed to this pressure.
