Contrec 515–SC06 Steam Flow Computer

Contrec 515 Series with SC06 application measures the volume, mass and energy content of steam by using single or stacked differential pressure volumetric flow inputs in conjunction with a temperature and/or pressure input.

A selection of various modes makes it suitable for many steam applications. The instrument calculates the flow according to generic differential pressure equations and incorporates the conditions at which the flowmeter was calibrated.

The instrument calculates the mass flow and energy according to the IAPWS Industrial Formulation (1997) for the thermodynamic properties of steam. The equations use pressure and temperature values to determine the specific volume and the specific enthalpy.

CALCULATIONS

The steam energy calculations are based on the IAPWS Industrial Formulation (1997).

Superheated steam regions are:

0°C < t < 800°C P < 100MPa
32°F < t < 1472°F P < 14500psia

800°C < t < 2000°C P < 10MPa
1472°F < t < 3632°F P < 1450psia

Saturated steam regions are:

0°C < t < 374°C (critical temperature)
32°F < t < 705°F

P < 22MPa (critical pressure)
P < 3190psia

Water region is:

0°C < t < t saturation at system pressure
32°C < t < t saturation at system pressure

Formulas

Mass flow = Volume flow/Specific volume

Energy flow = Mass flow x Specific enthalpy
