Abstract
A mud flow measurement apparatus is described which is capable of measuring mud flow rate and density at or near the wellhead during a drilling operation. A riser assembly includes a torus wedge meter and density detection elements which are interconnected with a flow computer. Flow parameters are measured for unscreened drilling mud exiting a wellbore.
