Measured quantities
7 Application and measuring ranges
In this chapter, all values related to pressure are gauge pressure values.
7.1 Measured quantities
The SITRANS FC Coriolis flow meter can be used to measure the following fluids:
▪ Liquids
▪ Gases
▪ Mixtures, such as emulsions, suspensions, slurries
Possible limitations applying to measurement of mixtures must be checked with the
responsible Siemens sales organization.
The following variables can be measured using SITRANS FC:
▪ Mass flow
▪ Density
▪ Temperature
Based on these measured quantities, the transmitter also calculates:
▪ Volume flow
▪ Partial component concentration of a two-component mixture
▪ Partial component flow rate of a mixture consisting of two components (net flow)
The net flow is calculated based on the known partial component concentration and the
overallflow.
The mass flow, volume flow, net flow measurements can be bi-directional.
Measured quantities for NTEP custody transfer approval
Measurement variables for NTEP approval options C17 are:
▪ Mass flow unidirectional
▪ Volume flow unidirectional
