1. n. [Well Workover and Intervention]

A device installed on a mixing or pumping system manifold to measure the density of fluids. The density of fluids pumped into a well is frequently a key operating parameter, requiring constant monitoring and control. This is especially true when mixing slurries and transport fluids for solids, such as fracturing or gravel-pack fluids.

Alternate Form: densimeter
