Page 3 DESCRIPTION: The Fann Four Scale Mud Balance is an accurate, self-contained measuring device used to determine the density of drilling fluid. It has a range of 7 to 24 pounds per gallon or Specific Gravity of 0.84 to 2.88. The Mud Balance consists of a constant-volume sample cup and lid connected to a balance arm that has four graduated scales.
Page 4 CALIBRATION: The Mud Balance calibration can be checked using fresh water. At 70F (21C) fresh water should give a reading of 1.00 on the specific gravity scale, 8.34 on the lbs/gal scale, and 62.3 on the lbs/cu ft scale. This spot on the balance arm is marked with a longer scale division line called the water line. Small amounts of mud on the balance arm or rider can cause improper readings.
