The Foxboro CFT51 series digital Coriolis Mass Flow and Density Transmitter is an improvement of the CFT50 flow meters that introduced a completely new technology in the field of coriolis flow measurement. In combination with a Foxboro CFS10 or CFS20 flow tubes, the CFT51 series forms a mass flow and density meter. The digital signal processing (DSP) offers improved flowmeter performance and adds new functions to previous transmitter versions. The CFT51 uses HART or Modbus protocol for remote communication.
