DC52 series of process meters has been carefully engineered to fit large range of applications within the oil and gas, petrochemical, chemical, food processing and other industries.
Use the proven vibrating element technique that is widely accepted as the most accurate method of continuous online density measurement, LEMIS process engineers did new step ahead introducing unique proprietary design of streamlined resonant tube that is washed on either side by measured liquid. The oscillation period of the vibrating tube and its frequency characteristics depend on behaviour of the measured liquid allowing simultaneous and accurate direct measurement of both density and dynamic viscosity, and future calculation of kinematic viscosity. An integral high accuracy Pt100 temperature probe provides liquid temperature measurement that allows calculation of reference density and viscosity.

VDC-30 principle of operation is based on the changing of frequency characteristics of the sensitive element in the measured liquid. Device measures continuously Dynamic Viscosity and Real Density to calculate Kinematic Viscosity of the liquid.
Usually all the industrial measuring systems operate with dynamic viscosity unlike most of laboratories measure kinematic viscosity via capillary viscometers. So it is critically important to compare laboratory measurements with measurements made by process meters and evaluate measuring system`s performance.

Portable Submersible Viscometer VM-250 SERIES best suited for liquid viscosity and temperature measurements directly in the storage or process tanks (up to 6 meters depth). No labor extensive and errors critical sampling required. Instead, the sensors of VM-250 SERIES can be submersed at any required level and record spot viscosity and real temperature at that point directly in the liquid. The operation personal can get in minutes the average viscosity in the tank and its viscosity / temperature / level profile, for example, at every meter. Hundreds of measurements can be stored locally and future transferred to a PC or printer via built-in bluetooth connectivity. The VM series have robust design for heavy duty year round indoor or outdoor operation, even in severe climatic conditions at –40°C to +85°C (-40°F to +185°F). Backlighted LCD facilitates nighttime operation.
Viscosity determination directly in the tanks is faster, easier, more precise and cost effective comparing with conventional technique requiring sampling and use of glass capillary viscometers by qualified personal in laboratory. That is why the portable viscometers from LEMIS process have found wide application, first of all in oil industry upstream and downstream operations where control of quality (viscosity) of petroleum products at movement and storage is very critical. Continually, the VM series gain success in other industries proving obvious advantages and cost effectiveness compare to traditional methods.
