Nametre™

Viscometers

Delivering the Utmost in Ease-Of-Operation, Precise Measurements, Consistent, Field-Proven Performance – and Value

Whether you are blending asphalts or foods, refining oil or petrochemicals, or manufacturing consumer products, pharmaceuticals, or industrial polymers – precision, real-time viscosity measurements are critical to assuring product consistency and quality. Equally important in today’s competitive environment, well-placed viscometry measurement lets you optimize your processes for increased efficiency and lower costs. Galvanic’s Nametre viscometers are dual-component systems comprising a ViscoLiner® controller and a sensor with a variety of probes* to suit most applications − making accurate process measurement easy, reliable, and cost-effective in even the harshest process setting.

Hermetically sealed from the process and welded to a base, ViscoLiner sensors can be mounted in any position within a reactor, tank, or pipe. This way, real-time measurements are taken exactly where and when it’s most effective for process optimization and control to improve process economics. The sensor resonates torsionally and its oscillation is servo-controlled at a constant amplitude. A change in viscosity of the material surrounding the probe results in a change in the amount of electrical power required to maintain the constant amplitude. This change in power is a mathematical function of the material’s viscosity. Constant mechanical amplitude provides superior measurement precision. Nametre viscometers are factory-calibrated to NIST-traceable standards with Newtonian fluids so a second instrument will provide the exact same results as the first one. Cost of ownership, therefore, is reduced to a minimum.

*The controller was formerly referred to as ViscoScope model VS600 and the sensor was model VL500 or VL800

Features

  • Reliable measurement in harsh flow conditions – varying flow rate, suspended solids, high temperature, and high pressure
  • Flow variations as generated by a tank stirrer or agitator and pipeline flow does not influence the measurement
  • An RTD (PT100) is integrated into the sensors to provide temperature measurement at the same location as the viscosity measurement
  • Safety barriers (i.e., Zener) are used to make ViscoLiner sensors suitable for installation in hazardous areas
  • Factory-calibrated to NIST-traceable standards and no moving parts − because there is no wear and tear from the instrument itself, recalibration is not necessary
  • 3 optional 4 to 20 mA outputs configurable to displayed viscosity, temperature, etc.
  • Optional Hi/Lo relays
  • Optional RS232 or RS485 Modbus
