ABSTRACT:
An improved liquid filled gauge for measuring the temperature or pressure of a fluid. Gauge temperature or pressure readings are indicated by a pointer configured to produce substantial resistance to motion during pointer rotation. The preferred embodiment employs an elongated flat sheet pointer having three 90.degree. twists; two in the indication end of the pointer to bound a first resistive surface, and a third in the tail of the pointer to bound a second resistive surface.
