Barton's Scanner(R) Family of Flow Computers Reduce Operating Costs and Maximize Profits in Natural Gas and Hydrocarbon Liquid Processing


Functionally and computationally superior Electronic Flow
Measurement/Remote Telemetry Units (EFM/RTUs) support all common primary devices

City of Industry, Calif. (December 5, 2001) -- Barton's powerful, fast and flexible Scanner(R) EFM/RTUs provide custody transfer measurement data and control functions to production, transmission, and distribution markets. Available in either field
mount or rack mount configurations, Barton's intrinsically safe flow computers reduce operation costs and maximize profits by providing accurate information for monitoring, measurement and control of natural gas or hydrocarbon liquid processing. The
Scanners are either solar or 24 VDC powered and provide fast, flexible operation including selectable sampling frequency, user calibration points (linear or custom), number of points, hysteresis correction, and static pressure effect compensation on
different pressure inputs. To enhance and simplify the process of configuring and communicating with remote EFM/RTUs, Barton's ScanWin® and other data management software tools are available. Using a Windows-based platform, ScanWin® is able to guide operators through the process of setting up hardware, flow runs, controllers, and primary devices as well as collecting hardware, system, and flow run data.

The Scanner 1131 works with up to 12 user-defined inputs. These multi-stream inputs can be from orifice and turbine meters, RTDs, low-power transducers and transmitters, and the Barton dual-pressure electronics sensor, which provides both static and differential pressure readings. Status outputs can be used to trigger external devices such as counters and alarms. The system employs an Intel 386 EX 16/32 bit embedded processor operating at 16-20 MHz, making it more than adequate for fast computational operation. Four serial communication ports are also available.

The Scanner 1140 and 1140C single-stream flow computers work with 1 flow run input, using Barton's dual pressure electronics sensor, and 1 RTD input. They also feature 2 analog channels for local signals, 4 digital inputs/outputs for control and status and 1-4 to 20 mA output and 1 frequency input. Configuration can be performed on-site or remotely with optional communications capability. Up to 60 days (hourly and daily) flow history can be stored with an audit trail of all events, alarms and user changes. The 1140C computer has all of the functionality of the 1140 with the addition of communication via integral radio, modem, cell phones and LEO (Low Earth Orbit) satellite.
