Versions
The SITRANS FC flowmeters uses the Coriolis principle to measure flow and is available in a
remote and a compact version.
● Compact version: The MASS2100 is a single mechanical unit where the transmitter is
directly mounted on the sensor.
● Remote version: The MASS2100 sensor unit is remotely connected to a SITRANS FCT
transmitter. Directly mounted on the sensor, its Digital Sensor Link (DSL) performs the
signal processing of all measured signals in the sensor. The 4-wire connection between
the transmitter and the sensor provides power and high-integrity digital communication
between the DSL and the transmitter.

Sensor design
All primary process measurement of massflow, volumeflow, density and process temperature
are made in the DSL/sensor front end.
The sensor comprises one single continuous bended tube, with no internal welds. The sensor
is available in an intrinsically safe (IS) design for hazardous area installations.
The sensors are available in AISI 316L stainless steel and Hastelloy C22. The enclosure is
made of AISI 316L stainless steel.
The sensor enclosure can be equipped with a pressure guard or flushed with dry inert gas at
the threaded ports for non-hazardous applications only.
In the remote configuration, the sensor front end (DSL) is available in an aluminum enclosure
with an ingress protection grade of IP67/NEMA 4X. For communication and power supply a 4-
