The SITRANS F C MASS 2100 DI 3-15 is suitable for accurate mass flow measurement for all kind of liquids and gases. The full bore design provides lower pressure loss due to the same internal diameter throughout the entire sensor and the single tube construction without internal welds, reductions or flow splitters offers optimal hygiene, safety and CIP cleanability. The sensor is also characterized by having a large dynamic turn down range better than 500:1 and the market’s thickest tube wall to ensure the highest integrity.

Integral heating is optionally available to avoid solidification of sensitive fluids during downtime or period between discontinuing processes.

In order to make a complete flowmeter, the SITRANS F C 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
SIFLOW FC070: For direct integration into SIMATIC based systems
SITRANS F C MASS 6000 (only remote installation): For general industry applications


Typical applications: Dosing within the chemical industry (dosing of chemicals), Food & beverage industry (beer, juices, liquids such as chocolate, dressings) and Automotive industry (Engine test rigs)

  • Center-block design decouples process noise from the environment such as vibrations, pulsations, pressure shocks etc. making installation flexible and versatile
  • Rugged and space-saving sensor design in stainless steel matching all environments
  • Multiplug electrical connector and SENSORPROM enables true Plug & Play facilitating cost-efficient installation and commissioning
  • 4-wire Pt1000 temperature measurement ensures optimum accuracy on mass flow, density and % fraction
  • Intrinsically safe Ia II C as standard, making service in the harzadous area possible without having to demount the sensor if the compact Ex d transmitter needs service
