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 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 highest integrity.

Integral heating is optionally available to avoid solidification of sensitive fluids during down time 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 chemical industry (dosing of chemicals), Food & beverage industry (beer, juices, liquid such as chocolate, dressings) and Automotive industry (Engine test rigs)
