NuFlo Cone Meter (DP Input). The Scanner 2000 supports steam measurement using industry-recognized
algorithms identied in the NuFlo Cone Meter User Manual. Fluid properties for steam are calculated
in accordance with the IAPWS Industrial-Formulation 1997 (IF-97) standard. Temperature is calculated
according to IF-97 for saturated steam, based on static pressure. Therefore, an RTD is not required. The
optional Steven wet correction method is supported for the measurement of vapor and uid.
Averaging Pitot Tube Meter (Annubar
®
). The Scanner 2000 supports steam measurement based on ASME
MFC-12M -2006 ow rate methods for averaging pitot tube meters. Fluid properties are calculated in
accordance with the IAPWS Industrial-Formulation 1997 (IF-97) standard. Temperature is calculated
according to IF-97 for saturated steam, based on static pressure. Therefore, an RTD is not required. Wet
correction methods are not supported.
Compensated Liquid
The Scanner 2000 measures compensated petroleum liquid ow using an orice, cone, liquid turbine, or
averaging pitot tube (Annubar
®
) owmeter. Users can select either of two uid property calculation methods
for use with any of these owmeters.
• The “generic” uid properties calculation method is used to measure liquids such as water or emulsions,
based on user-supplied viscosity values and either user-supplied density values or user-supplied liquid
thermal expansion coefcients.
• The API-2540 calculation method provides temperature corrections for the following petroleum liquids:
crude oil, gasoline, jet fuel, fuel oils, and lube oil.
Orice Plate (DP Input). The Scanner 2000 calculates ow rates in accordance with AGA Report No. 3, Part
1 (1990) or ISO-5167 (2003) methods. When measuring liquids, the expansion factor (Y) is always equal to
1.0. Fluid property calculations for temperature-compensated measurements are based on API-2540 (1980),
Petroleum Measurement Tables.
NuFlo Cone Meter (DP Input). The Scanner 2000 calculates ow rates in accordance with industry-
recognized algorithms identied in the NuFlo Cone Meter User Manual. When measuring liquids, the
expansion factor (Y) is always equal to 1.0. Fluid property calculations for temperature-compensated liquids
are based on API-2540 (1980), Petroleum Measurement Tables.
Liquid Turbine Meter (Frequency Input). The Scanner 2000 calculates ow rates in accordance with the
measurement principles upon which the AGA-7 standard is based. The user supplies a linear or multi-point
calibration factor, and the instrument performs the required compensation calculations, based on the RTD
input.
Averaging Pitot Tube Meter (Annubar
®
). The Scanner 2000 calculates ow rates in accordance with the
ASME MFC-12M-2006 measurement standard. When measuring liquids, the expansion factor (Y) is always
equal to 1.0. Fluid property calculations for temperature-compensated liquids are based on API-2540 (1980),
Petroleum Measurement Tables.
Uncompensated Liquid
The Scanner 2000 measures uncompensated liquid ow based on the input from a liquid turbine or PD meter.
Liquid Turbine Meter (Frequency Input) or PD Meter (Pulse Input). The Scanner 2000 calculates ow rate
from a liquid turbine meter via a frequency input, or from a contact closure (which requires the pulse input on
the optional expansion board). Flow rates and totals are calculated using a user-supplied linear or multi-point
calibration factor in accordance with API Manual of Petroleum Measurement Standards, Chapter 5, Section 3,
Measurement of Liquid Hydrocarbons by Turbine Meters (2005).
