The new generation TUF-2000M is developed with the experience of 12 years of manufacturing and based on our version-7 and version-11 flow meters. By using the high performance MSP430FG4618 microprocessor made by Taxes Instruments, it is intend to provide our customers with lower cost but of high performance general purpose ultrasonic flow meter/heat meter/ultrasonic flow converter.

The PCB board used in a TUF-2000M module is our 13th version of ultrasonic flow meters, so that we usually call it version-13 flow meter. The PCB board measures 116x62 millimeter. It is encased in a plastic rectangle case that could be plugged easily onto an installation rail. The power supply is 8~36VDC@50Ma (10~36VAC is also applicable). It is equipped on board with a 96-segments LCD display, an isolated 4~40mA current output, 3 ways of analog input, one Serial Expanding Bus socket, 2 ways of OCT switch output, 2 ways of PT100 RTD inputs, one isolated and surge protected RS485.

The TUF2000-M flow meter can be applied to a wide range of pipe flow measurements. Applicable liquids include pure liquids as well as liquid with small quantity of tiny particles.

Examples are:

★ Water (hot water, chilled water, city water, sea water, waste water, etc.);

★ Sewage with small particle content;

★ Oil (crude oil, lubricating oil, diesel oil, fuel oil, etc.);

★ Chemicals (alcohol, acids, etc.);

★ Plant effluent;

★ Beverage, liquid food;

★ Ultra-pure liquids;

★ Solvents and other liquids
