    Scanner® 1141 Single & Dual Stream Measurement Remote Telemetry Unit (RTU)



    Cameron's Measurement Systems Division, manufacturer of Barton® Chart Recorders, the most rugged and reliable chart recorders in the world, continues to lead the way in accurate and easy to use gas measurement and control instrumentation. The Scanner 1141 is a single and dual stream measurement RTU designed specifically to provide flow monitoring and control for oil and gas gathering and production operations. Featuring a full range of operator-configurable mass, energy, and volume algorithms, the Scanner 1141 simplifies the collection, processing and transmitting of data.

    New application programs (firmware) can be loaded to the FLASH ROM using Scan Flash
    or Winsload utility programs on a Microsoft Windows® compatible PC.
    A memory backup battery powers the clock and maintains the contents of the memory for
    1 year minimum with no power.
    Display The “autoscroll” alphanumeric display provides quick access to current readings; parameters shown
    are user-assignable. The display can be activated by a push button on the main board, or it can be
    configured to always be on. The manual contrast adjustment is factory-set to optimize the display
    contrast and automatically adjusts for temperature variance.
    Backlighting is available on some hardware configurations. A jumper selection allows the user to turn
    only the backlight off or to turn the display off to conserve power.
    Type LCD, 2 line x 16 alphanumeric characters
    Viewable Area 99 x 24 mm (3.9 x 0.9 in.)
    Operating Temperature -20°C to +70°C (-4° to 158°F)
    Storage Temperature -40°C to +80°C (-40° to 176°F)
    System Board I/O Summary The system board contains the central processing unit, FLASH EPROM memory, RAM, NVRAM, interface
    circuitry for the display, and up to four serial ports. The system board provides analog I/O and status/pulse
    I/O to support up to two natural gas or liquid flowruns with proportional/integral control.
    (CL) Current Limited Transmitter Supply:
    Current limited output that is powered from the battery or power input voltage (whichever is higher).
    Approximately 50 mA.
    (12VL) 12V, 30 mA Voltage Limited Transmitter Supply:
    Outputs the higher of the battery and power input voltages, from less than 0.25V to a maximum of 12V.
    (12V Step-up) 12V, 30 mA Step-up Transmitter Supply:
    Outputs 12V regardless of battery and power input voltages, recommended for 6V systems with 12V transmitters.

    Power Supply & Battery For Division 2 applications, the main board includes an integrated 10-amp temperature-compensated battery
    Charge Controller Options charger. The charge controller can be firmware-configured to work with either 6V or 12V sealed lead acid
    batteries. The input supply must be limited to 10A DC. Input is 6 to 28 VDC.
    Peripheral Power Supplies Two separate short-circuit protected outputs are available for powering radios and other devices:
    • a +5V @ 200 mA output that can be used to directly power +5V radios or to act as a logic-level control signal
    for +12V radio systems; FL configurator only
    • a protected switch that outputs the same voltage as the battery, maximum 18 watts, example 1A @ 18V
    Both supplies can be scheduled to turn on and off in firmware to conserve power, and to shut off when the
    low battery alarm is active.
