Abstract
A device for simultaneously measuring various parameters such as the flow rate, the density and the temperature of the drilling mud issuing from a well during the drilling operation, and for recording said parameters, comprising a V-shaped measuring conduit the upstream portion of which is connected to the upper portion of a chute through which said mud flows and which opens into the atmosphere, while the downstream end of said measuring conduit is connected to a down spout directing said mud to oscillating screens.
