The SITRANS FC MASS 2100 DI 1.5 has demonstrated superior performance in numerous applications and field trials relating to mass flow- and density accuracy and turn down ratio. The single continuous tube design without internal welds, reductions or flow splitters, offers optimal hygiene, safety and CIP cleanability for food & beverage and pharmaceutical applications. This makes the SITRANS FC MASS 2100 DI 1.5 the preferred meter for research and development and mini-plant applications for liquid or gas measurement, where measuring very small quantities (e.g. drops per hour) is important.

Select and order

In order to make a complete flowmeter, the SITRANS FC MASS 2100 flow sensor must be combined with one of the following MASS transmitters:


SITRANS FCT030: For general industry applications
SITRANS FCT010: For OEMs and skids in applications where space is limited
SITRANS FCT070: For SIMATIC ET 200SP distributed I/O 


  • Markets smallest and most stable zero point - Dual-drive pick-up and driver construction facilitate ultra low-weight pipe construction
  •  Optimal lifetime - Markets biggest wall thickness,corrosion resistent and high pressure durability
  •  Plug & Play - Multiplug electrical connector and SENSORPROM facilitate cost efficient installation and commissioning
  •  Enhanced safety - standard intrinsically safe EEx ia design
  • Outstanding accuracy - 4-wire Pt1000 temperature measurement for reliability in mass flow, density and % fraction
