ABSTRACT:
Fluid density is measured in a fluid speed indicating apparatus by using a pair of rotor arms having a pair of asymetrically located venturis or equivalent venturis. A steady state pressure difference will be produced between the two pressure locations and will be a function of the rotational velocity and fluid density. Since the rotational velocity is a known constant, the fluid density can be derived directly from the steady state pressure difference.
