Mud and Slurry Density Transmitter

PSM has designed and developed the 290 Series as a mud and slurry density transmitter specifically for use in the onshore and offshore oil and gas market. It is the first fluid density transmitter that is fully submersible for use in drilling mud and fluid circulation tanks.

This density transmitter is rugged yet accurate, providing reliable measurement of the density or specific gravity in drilling mud holding tanks and return sumps.

290 Series

The 290 Series transmitter measures density as a function of differential pressure. Each unit has two pressure sensitive diaphragms mechanically separated by a fixed distance on a mounting pole. Under normal operation, with both diaphragms submerged and the distance between them fixed, any variation in the pressure differential between them must be a function of the liquid density. The diaphragms are protected by enclosure cages to prevent damage from mechanical impact or debris.

Key Features

  • Designed specifically for mud and slurry density measurement in oil and gas drilling applications
  • Rugged, reliable and accurate with field proven operation in hundreds of installations
  • Pressure sensor diaphragms are protected against mechanical damage
  • Compact with a simple installation
  • 2 wire 4 to 20 mA industry standard output
  • Intrinsically safe versions available
