Applications
Measurement of liquids and gases
SITRANS F C Coriolis mass flowmeters are designed for measurement of a variety of liquids
and gases. The flowmeters are multi-parameter devices offering accurate measurement of
massflow, volumeflow, density, temperature and, depending on product variants, fraction,
including industry-specific fractions.
Main applications
The main applications of the Coriolis flowmeter can be found in all industries, such as:
● Chemical & Pharma: detergents, bulk chemicals, acids, alkalis, pharmaceuticals, blood
products, vaccines, insulin production
● Food & Beverage: dairy products, beer, wine, soft drinks, °Brix/°Plato, fruit juices and pulps,
bottling, CO
2
dosing, CIP/SIP-liquids, mixture recipe control
● Automotive: fuel injection nozzle & pump testing, filling of AC units, engine consumption,
paint robots
● Oil & Gas: filling of gas bottles, furnace control, test separators, bore-hole plasticizer dosing,
water-cut metering
● Water & Waste Water: dosing of chemicals for water treatment

Approvals
Note
For further details see Approvals (Page 239).
The device is available with approvals for general purpose and for hazardous areas. In all
cases, check the nameplate on your device, and confirm the approval rating.

Theory of operation
The Coriolis principle of measurement
The flow measurement is based on the Coriolis law of motion. Particles moving in a rotating /
oscillating system will resist imposed oscillations in a manner consistent with their mass and
velocity (momentum). Oscillation produced by a Coriolis flowmeter where the process media
is accelerated around bends results in phase distortions of the measuring tubes.
The SITRANS F C sensors are energized by an electromagnetic (voice coil) driver circuit which
oscillates the pipes at their resonant frequency. Two pickups are placed symmetrically on either
side of the driver to provide position signals for digital processing.
