Abstract
A drilling fluid density measurement system uses a continuously operating bubble measurement system for an oil or gas well. A microprocessor correlates the signal output from a differential pressure transmitter connected to a pair of self-cleaning pressure probes which are positioned in a circulating drilling fluid. By manipulating solenoid valves, the microprocessor controls the intermittent zeroing of the output signal from the differential pressure transmitter and controls a periodic level check to determine if the pressure probes are submerged in the drilling fluid.
