DYNAMIC VISCOSITY

IN PROCESS TO EXCELLENCE WITH

LEMIS PROCESS

Dynamic viscosity is a critical part and an important parameter for qualitative process control of a given liquid. Dynamic viscosity determination is required for wide range of products such as lubricants, oils, fuels etc.

LEMIS process offers the way to optimize your costs without saving on accuracy and repeatability of your measurements!

Our customers say: “to control dynamic viscosity means to control quality of the product”. It means faultless equipment that provides qualitative production, no errors, no downtimes, costs optimization and economy. LEMIS process viscometers range secure stabile continuous control at any conditions. All required measurement methods are supported: continuous in-tank or in-line; repeatable by portable meters (using submersible sensors without sampling or laboratory sensors with sampling). It is not an exaggeration to say that LEMIS process meters can operate everywhere and give the most accurate measurements.LEMIS Process offers a turnkey solution foryour process industry, providing many advantages to you as a customer. An individual approach, flexibility, tailored to your process solutions.

Unique resonant tube technology

The LEMIS process sensor comprises of a vibrating tube sensor, drive electronics and signal processing electronic.

ü Cylinder shape has symmetric geometry

ü Repeatable mechanical manufacturing

ü Repeatable metal structureü Low own mass of the sensorü Washed on either side by

measured liquid eliminates pressure effect

ü Allows both density and viscosity measurement

ü Ni-Span-C material offering low temperature expansion factor

Quickly measures dynamic viscosity of a liquid product in

tank.Measures level of liquid

products in the tank.They’re economical and easy to

operate.Calibration couldn’t be

simpler just use standard liquids.

Select a VM version according to the testing depths

you require.

VM-250.1 plunges to 6 meters, while VM-250.2 reportsdynamic viscosity and temperature measurements at

30 meter depths in seconds.Measures highly viscous liquids up to 1200 cP.

CalibrationCalibration of LEMIS process is

performed in-house according

ISO9001:2000 quality

assurance program by using

calibration materials that are

traceable to national standards.

In-house calibration and testing

is performed specified

dedicated calibration protocol

for every standard model of the

sensor. For most applications,

on-site calibration is generally

not required. LEMIS process

sensors allows simple, switch-

and-go field installation.

ApplicationsViscosity and temperature monitoring in storage tanks

Petroleum products, fuels, lubricants, LPG, LNG

Concentrations of acids or corrosive chemical

Food, Dairy & Beverages

Product identification and consistency

Concentration and dilution measurement

Monitoring of reaction end in reactors

In-tank mixing and blending

AdvantagesContinuous measurements

Easy cleaning
