The display will shut off automatically after a configurable amount of time (usually about 30
seconds). To “wake-up” the display, press the “wake-up” button.
Scanner Software
ScanWin Lite is a Windows
™
-based software program for monitoring, configuring and
downloading Scanner Measurement RTU data on-site. ScanWin Lite’s “wizards” guide the
operator through the setup of hardware, flow runs, and primary devices as well as the collection
of hardware, system, and flow run data. Reports can be exported and printed from ScanWin.
ScanWin Lite also facilitates the upload and download of configuration settings.
ScanWin Pro, an optional upgrade from ScanWin Lite, combines all of the functionality of
ScanWin Lite with a flow run catalog and a relational database that stores historical information
for off-line review. ScanWin Pro also supports the configuration of advanced control and data
capture functions and various connection methods for remote communication with the Scanner
1141.
Scanner Firmware
The Scanner 1141 supports current NGas, NFLo and IGas firmware. Gas calculations meet both
North American (NGas/NFLo) and international measurement standards (IGas).
All three programs accept signals from orifice or turbine meter inputs and RTD temperature
inputs. Gas composition values can be automatically updated through a gas chromatograph
interface using the RS-232 communications port, or they can be manually entered.
All calculations are performed in SI metric units. The Unit Manager automatically converts other
units as required.
IGas
The international standard (IGas) includes ISO-5167, which supports a variety of differential
pressure meters, venturi and flow nozzles. ISO-T30SC1088 is supported for turbine meter
measurement.
NGas
NGas firmware solves Manual of Petroleum Measurement Standards (MPMS), and American
Gas Association (AGA) (Reports 3 (1992), 5, and 7) calculations including volume, mass, and
energy. The calculation speeds meet or exceed API standards for flow computers. The
supercompressibility calculations performed include:
•
AGA-8 (1992)
•
Redlich-Kwong
•
