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 controof finaproduct 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 signaprovides a variety of display and controcapabilities
  • 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", 1?", or 2" pipeline connections; tri-clamp; 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 optionaIECEx, ATEX, and North American explosion-proof certifications


  • TT-100 IECEx model certified to IECEx, ATEX, and North American explosion-proof standards
  • Variable speed motor
  • Computer controlled variable speed viscometer
