New online analyser able to directly monitor kinematic viscosity at reference temperature

Sofraser’s (France) Thermoset-KV is a powerful online analyzer specially designed to directly measure kinematic viscosity at reference temperature.

The measurement principle is based on the vibration at

resonance frequency technology developed and patented by Sofraser in 1981. The active part of the

measurement is a vibrating rod driven by constant electrical power. The amplitude and the

frequency vary according to kinematic viscosity.

Compared to other technologies available on the market, the Thermoset-KV is the only analyzer able

to directly monitor kinematic viscosity and to provide measures in cSt (up to 500 cSt). Matched with

9731 electronics, the analyzer provides an intuitive interface (touchscreen display, virtual keyboard).

With its hazardous area approved design, the Thermoset-KV is really simple to install close to the

main process flow line, directly on an existing secondary sampling loop or even on a fast loop.

Designed to prevent clogging, it requires minimal extra-installation. The analyzer uses a flow-cell that

is maintained at reference temperature and in which the product flows along the sensor. Direct

kinematic viscosity is then measured in real time on the same product, at the same time and with the

same instrument.

In compliance with Oil & Gas industries requirements, the Sofraser’s viscosity analyzer is directly

correlated to ASTM D445. It affords efficient analysis and monitoring of a single control point (one

target viscosity point at one reference temperature) while maximizing return on investment.

Sofraser’s Thermoset-KV is specially designed for kinematic viscosity at reference temperature

monitoring of various petroleum products such as crude oils, heavy and light fuel blends, visbreaking

etc. Through its various models of analyzers, Sofraser offers a solution for any application.
