Mud density meter

Drilling Fluids & Logging

A mud density meter (or densiometer) provides a continuous, automated reading of the drilling fluid density entering or leaving the well. It typically uses a radioactive source (nuclear densiometer) or a Coriolis mass flow meter.

Real-time density monitoring is safer than manual mud balance checks (which are point-in-time) because it can instantly detect 'cut' mud (gas influx) or weighting up events.
