In the above table, the DES series densitometer from PhoTime Inc. of the United States is undoubtedly the best choice in terms of both performance and price.


PHOTIME)DES series densitometers: click to enter


DES series on-line densimeter is a high-precision density measuring instrument based on differential pressure principle introduced by PHOTIME Company.  It is an instrument for continuous on-line measurement of liquid density and is mainly used for automatic control of industrial processes.  DES series on-line densitometers are based on Archimedes principle: P=ρgh, the static pressure of a liquid column at a certain height is proportional to the density of the liquid, so the density of the liquid can be measured according to the static pressure value measured by a pressure measuring instrument.  Guangzhou won the exclusive agency authorization of U.S. Fortis DES Densitometer in 2011.



PHOTIME inc. introduces:

U.S. Forte Company is a professional high-tech company in the field of industrial on-line measuring instruments and meters. The company is located in Austin, known as Silicon Valley in the central United States. It was founded in 2001 by senior technical and market experts in the field of instruments and meters and famous scholars in the field of modern sensing science.  Fu Tai Company has many internationally leading patented technologies in flow measurement and on-line analysis instruments, and has become the most growing enterprise in the same field by cooperating with Thermo Fisher, Baker Hughes and other companies to develop on-line measurement products and industry standards.


DES densimeter product features:


◎ 4-20mA, Hart bus or RS485/MODBUS communication function is adopted

◎ The instrument itself has its own level to ensure the accuracy of field installation

◎ Online remote check, digital local display

◎ Touch screen display interface is more friendly

◎ Wireless remote communication


Features of Touch Screen Densitometer Converter:


TS-3200 Intelligent Density Meter Converter is a new type of density meter converter specially designed for DES series on-line density meters (compatible with wall hanging, embedded and desktop mounting methods).  It integrates many functions such as display, processing and recording, and can collect, save and analyze the data of liquid density in industrial process, providing a convenient, intelligent and modern management window for industrial application site.  It has an RS-232 communication interface, an isolated RS-485 communication interface and a U disk interface.  The collected data are stored in RAM memory, which can display real-time data or recall historical data in various forms such as curves, engineering quantity data and percentage components, and can also transmit data remotely through RS-232 or RS-485 communication interface.


At present, it has been widely used in various industrial fields such as petroleum, chemical industry, food, brewing, paper making, mining, sugar making, pharmacy, dairy products, etc.
