Abstract
A system for measuring a flow parameter of a fluid, comprising a conduit defining a flow passage for said fluid, said flow passage having a central axis means located in said flow passage for measuring a differential between a first resultant drag exerted by said fluid at a first distance from said central axis and a second resultant drag exerted by said fluid at a second distance from said central axis different from said first distance and means for determining said flow parameter from said differential, whereby said flow parameter is accurately measured regardless of viscosity changes in said fluid.
