TT-100 Viscometer

TT100 201x583

Now available with IECEx, ATEX, and North American Explosion-proof Certifications.

The TT-100 In-Line Viscometer is designed to provide years of trouble-free service in closed loop systems which require constant monitoring and associated control of product viscosity.


  • Continuous measurement eliminates need for "Grab" sampling and allows for prediction and constant control of final product properties
  • Concentric cylinder geometry (Couette type) provides viscosity measurements at defined shear conditions
  • Defined shear means agreement with Brookfield Laboratory measurements at equivalent shear rates
  • Constant or variable speed motors available
  • 4-20 mA output signal provides a variety of display and control capabilities
  • Capable of a wide range of pressures, temperatures, viscosities, flow and shear rates
  • Measurement "Zone" is protected from main flow, allowing accurate, repeatable measurement under variable conditions
  • Mounts in-line supported by connections: Available in 1", 1½", 2", or 4" pipeline connections; sanitary, threaded or flanged
  • Easy to check and maintain calibration
  • Can be operated at shear rates of 511 sec-1 as required by the Standards of the American Petroleum Institute (API)
  • Use in hazardous locations worldwide with optional IECEx, ATEX, and North American explosion-proof certifications



  • Viscosity Range: 10 - 500,000 (cP/mPa·s)
  • Speeds: Single speed: application specific
  • Input Power: 115 Vac: 50/60 Hz 230 Vac: 50/60 Hz 24 VDC
  • Output: 4 - 20 mA



  • TT-100 IECEx model certified to IECEx, ATEX, and North American explosion-proof standards
  • 3A approved food grade design STT-100
  • Variable speed motor
  • Computer controlled variable speed viscometer
