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.
