A system, or apparatus combination, and apparatus components, for the measurement of fluid flow. Such system, or apparatus can be used, e.g. for measuring the amount or flow of drilling fluid, or mud, introduced into a well bore, the amount or flow of mud returned from the well bore, and differences in flow rate and density between the mud introduced into the well bore and the mud returned from the well bore. The system measures or calculates, inter alia, flow rates, viscosity, temperature, density and gas content and compensates for variations; and in marine installations the system additionally measures vessel motion and compensates for wave and tide motions.

A constant area flow conditioning and process sensing instrument mounting block for mating engagement with a straight section of meter tube such that a particle-containing fluid can flow through said block and meter tube, which comprises: an axial opening extending through said block from a front face to a rearward face, outer faces one or more of which is provided with a lateral opening extending from an exit side thereof into said axial opening and into which a process sensing device can be mounted with an essentially flat diaphragm portion thereof flush with a flat wall surface surronding the exit side of said lateral opening, indentations of hemi-elliptical shape cut within said wall surface to the front and rear of said lateral opening, the narrow side of each identation being relatively shallow and touching alternate sides of said lateral opening while the wider side of each identation is cut deeper into said wall surface and faced away from said lateral opening, the forward indenation providing an upwardly inclined slope which, when said particle-containing fluid is passed through the block from an upstream source, directs the particles upwardly and prevents direct impingement of the particles upon the face of the diaphragm of a primary sensing device fitted into a lateral opening.
