KV100 Capillary Viscometer

For Low Viscosity In-Line System Applications

Product Description

KV-100® Viscometer

Model KV100 is a user-friendly capillary viscometer which operates excellent in rough process environments, on downgraded set-ups at pilot plants, as well as under semi-laboratory conditions.

The KV100 Capillary Viscometer easily measures low and medium viscosity materials. Based on the principle that the pressure decrease between the two ends of the measuring capillary is proportional to viscosity a permanent control signal is determined.

Features And Benefits

  • Continuous measurement eliminates need for "Grab" sampling and allows for prediction and constant control of final product properties
  • The gear pump forced internal sample flow via magnet coupling keeps the instrument resistant to pressure and temperature
  • 4-20 mA output signal provides a variety of display and control capabilities
  • Sample transport by aspiration tube into the viscometer creates bypass situation where measurement "Zone" is protected from main flow, allowing accurate, repeatable measurement under variable conditions
  • Availability of various standard viscosity ranges up to 500 mPas (cP); customized ranges on request
  • Display device for measuring data including calculation options
