Abstract
Apparatuses and methods measuring properties of drilling fluids in which the drilling fluid is contained in a structure, and a measuring device and a processor are used to measure the properties. The measuring device is immersed within the drilling fluid. The measuring device can comprise a shell defining a chamber, a weight adapted to cause the measuring device to sink through the drilling fluid, a transmitter and at least one sensor adapted to measure a property of the drilling fluid. The transmitter is adapted to transmit data representing the property to the processor.
