Portable Submersible Density meter DM-250.2 best suited for liquid density and temperature measurements directly in the storage or process tanks (up to 30 meters depth). No labor extensive and errors critical sampling required. Instead, the sensor of DM-250.2 is submersed at any required level and record spot density and real temperature at that point directly in the liquid. The operation personal can get in minutes the average density in the tank and its density / 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 DM series has 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 OLED facilitates nighttime operation.
Density determination directly in the tanks is faster, easier, more precise and cost effective comparing with conventional technique requiring sampling and use of glass hydrometers by qualified personal. That is why the DM series portable density meters from LEMIS process have found wide application, first of all in oil industry upstream and downstream operations where control of quality (density) and quantity (mass) of petroleum products at movement and storage is very critical. Continually, the DM series gain success in other industries proving obvious advantages and cost effectiveness compare to traditional methods.
