Option Description Measured variable
CA Mass; 316L; 316L (integrated temperature measurement) • Corrected volume flow
• Mass flow

• Energy flow
• Heat flow difference
• Specific volume
• Degrees of superheat
CB Mass; Alloy C22; 316L (integrated temperature
measurement)
DA Mass steam; 316L; 316L (integrated pressure/temperature
measurement)

temperature measurement)
Measuring range The measuring range is dependent on the nominal diameter, the fluid and environmental
influences.
The following specified values are the largest possible flow measuring ranges (Q
min
to
Q
max
) for each nominal diameter. Depending on the fluid properties and
environmental influences, the measuring range may be subject to additional
restrictions. Additional restrictions apply to both the lower range value and the upper
range value.
