What to do if Brookfield Measuring Instruments viscometer ranging is too high?
- J
  Joshua Ortiz MDAug 20, 2025
  If the viscometer ranging of your Brookfield Measuring Instruments is too high, and the reading is consistently less than 10% of the scale, it could be due to the viscometer being empty, partially empty, containing trapped air, no turnover of fluid in the measurement zone, improper calibration, the wrong operating range selected, or fouling of the torsion element and inner cylinder by solids. Make sure the viscometer is installed properly and clean the viscometer.

  connie41Aug 21, 2025
  If the viscometer ranging of your Brookfield Measuring Instruments is too low, with readings consistently greater than 90% of the scale, the possible causes are torsion element damage, improper calibration, or the wrong operating range selected.

Why Brookfield TT100 viscometer reading is over 100%?
- J
  Joe NicholsAug 23, 2025
  If your Brookfield Measuring Instruments viscometer reading is continuously over 100% of scale or different from a bench top viscometer, this may be due to: 1. Damaged torsion element. 2. Solids in measuring chamber. 3. Incorrect wiring on the sensing end cap. 4. Rheology of process fluid. 5. Temperature difference between process fluid on-line and fluid at bench top. You can ensure that both readings are taken at the same temperature.

What to do if Brookfield TT100 motor will not operate?
- Z
  Zachary SheppardAug 26, 2025
  If the motor of your Brookfield Measuring Instruments won't operate or needs assistance to operate, the possible causes are a damaged motor or gearbox, damaged drive shaft bearings or seal support seizure, the process system pressure or temperature setpoint has been reached, a damaged pressure or temperature interlock, or the motor being wired incorrectly. You can check the bearings, repair the process system, and verify the motor wiring.

What to do if Brookfield Measuring Instruments has no output?
- C
  Craig OlsonAug 27, 2025
  If your Brookfield Measuring Instruments has no output, no change in output when torqued, or no response to calibration attempts, it could be due to no power to the torque sensor electronics and motor control enclosures, a damaged torque sensor electronics board, a damaged Microsyn field coil, or the sensing endcap being improperly wired. Make sure power is applied to the torque sensor and motor enclosures.

What to do if Brookfield TT100 motor runs in either direction?
- M
  Michele FloresAug 30, 2025
  If the motor of your Brookfield Measuring Instruments runs in either direction depending upon assistance, the cause may be a damaged phase-shifting capacitor in the motor. You can replace the capacitor.

Why Brookfield Measuring Instruments motor rotation does not match torque response?
- N
  Nathan MitchellSep 1, 2025
  If the motor rotation of your Brookfield Measuring Instruments does not match the torque response, this could be due to the torque sensor response not being properly calibrated or incorrect motor wiring.

Why Brookfield TT100 has no change in output?
- P
  pjohnsonSep 2, 2025
  If your Brookfield Measuring Instruments shows no change in output when the motor is energized or when fluid changes, and there is no torque response, the possible causes are: 1. The viscometer is not completely flooded with process fluid. 2. The motor is not operating. 3. Solids build-up within the viscometer. 4. Open or shorted wiring to the Microsyn field coil assembly. 5. Damaged Microsyn field coil assembly. 6. Damaged torsion element. Make sure the viscometer is installed properly and clean the viscometer.

Why is Brookfield Measuring Instruments giving reverse torque response?
- H
  Heather HernandezSep 4, 2025
  If your Brookfield Measuring Instruments is giving a reverse torque response, it could be due to: 1. Incorrect coarse zero calibration. 2. Reverse motor rotation. 3. Incorrect transducer wiring.

Why is Brookfield TT100 Measuring Instruments giving partial torque response?
- R
  Richard AcostaSep 6, 2025
  If your Brookfield Measuring Instruments is giving a partial torque response, the causes may be: 1. Incorrect coarse zero calibration. 2. Excessive load on output. 3. Solids build-up within the viscometer. 4. Incorrect/shorted Microsyn field coil wiring. 5. Excessive friction on readout wire at jewel. 6. Damaged torsion element. 7. Incorrect span calibration. 8. Loose or misaligned armature assembly. 9. Optional elliptical baffle installed incorrectly. You can reduce the load and clean the viscometer.
