A system for real-time measurement of multiple properties of drilling fluids from a single sampling point may comprise: a pump for transferring fluids in the system, the suction of which may be alternately communicated through suction conduits with a reservoir of drilling fluids being measured and the source of cleaning fluids; valves connected in the suction conduits for alternately allowing or preventing fluid communication between the pump and the drilling fluid reservoir or the source of cleaning fluids; a weight measuring device connected to the discharge side of the pump for receiving and measuring the weight of drilling fluids therefrom; and a viscosity measuring device connected to the discharge of the pump for receiving and measuring indices of viscosity of the drilling fluids therefrom. A source of power is connected to the pump, the weight measuring device, the viscosity measuring device and control apparatus. The control apparatus is also connected to the pump, the weight measuring device and the viscosity measuring device for controlling the operation thereof.

Apparatus and method for real-time measurement of drilling fluid

A vane-type liquid meter in which fluid input to and output from an annular measuring space are directed parallel to the rotational axis of a rotor. The fact that a separation block within the annular space is kept in place in a self-adjusting way gives the advantage of high accuracy.
