This MIVI viscometer offers an incredible measuring range of 0,02 to 2 mPa.s. The new design of the vibrating rod is the major characteristic of this sensor.

Online viscosity index measurement and calculation according ASTM 2270-04

Sofraser's THERMOSET MIVI which is a powerful online process monitor can measure dynamic viscosity (up to 10 000 mPa.s) at two different temperature points. When adjusting the two reference temperatures at 100°C and 40°C, the THERMOSET MIVI is able to calculate the VISCOSITY INDEX according to ASTM 2270-04.

The fluid is permanently drawn from the process, brought at the required temperature, its viscosity measured at 100°C and 40°C, then re-injected in the main line. The density is simultaneously measured and the calculations are proceed by the 8003 controller. The system takes advantage of the recognized quality of the Sofraser's MIVI viscosity sensor and it's good reliability and accuracy. THERMOSET MIVI allows incredible time and money savings when installing, maintaining or cleaning. In most cases the system fits its own needs and requires no annex installation (as primary loops with exchangers, pump, filters, pressure controllers…). The absence of bath or oven allows immediate and secure maintenance.

SOFRASER instruments exhibit at Interkama in Hannover Messe (Germany) world most important industrial fair.

Hans Michael STÄHLE, from ST-A-PRO Stähle the German rep., joined Sofraser team composed of Dr Luc BELLIERE and Dr Philippe BURG. Very interesting project was presented to us maybe because we were the only viscometer manufacturer present this year.

Sometimes you have to measure the viscosity of your product no matter when and no matter where. Process inline viscometer isn't the solution and taking the sample to lab costs time. In order to answer to this increasing market's request, Sofraser especially developed the new PIVI portable viscometer for field, factory and laboratory viscosity measurement. PIVI can be supplied with any range from 0,1-100 mPa.s to 100-100 000 mPa.s and handles a wide set of products. PIVI uses the vibrating type principle and profits by all the related advantages : easy to clean, no wear part, simple, rugged, accurate and reliable. PIVI displays instantaneously the viscosity value, can store up to 40 measurements and has an RS 232 link. Like the Sofraser's process viscometers PIVI can be equipped with temperature probe and handle product temperature up to 100°C.

Sofraser has developed a special set to allow a measurement on a straight line pipe. This is made of a Tee, two standard flanges and a special MIVI flange. This assembly is easy and dismountable in less than fifteen minutes using regular tools. Sofraser's viscometer can be adapted on a standard T and a tube that is soldered and which length depends on the pipe diameter. The vibrating rod is protected.

This assembly has a good strength level and the viscometer unit creates no or very little energy loss. Measuring the viscosity can be performed only when the output flow is rather stable and laminar.

SOFRASER is proud to be one of the first small size French company to get the new iso version certification. This illustrates the continuous will of its management to be on the leading pool of high technology and quality companies.

SOFRASER was also one of the very first to obtain the new ATEX agreement for its products.
