Dual Orifice Bubbler
  • Dual Pressure Measurements
    • Measure Inflow and Outflow
  • Density Measurement
    • Measure Water Density
  • 2 Outputs - Orifice Tube Connections
  • Desiccant Mounts Outside of the Enclosure

The CFB’s Default Setting Will Operate The System Properly For Most Users - Very Little Change To the Initial Setup Is Required. -Default Bubble Rate is 90 Bubbles per Min.

-Default Measurement Interval is 15 Minutes

-Default 10 Second Averaged Measurement -Default Measurement Units is Feet of Water

-Default Purge Pressure 50PSI

  • 3 Ways to View and Modify the CFB’s Default Setting.
  • -Front Panel Key Pad and 2-Line Display
  • -SDI-12 Commands
  • -Command Line Interface Using Hyperterm or Procomm or Other Terminal Interface Software

-Command Line Interface

-Make Serial Connection to CFB using Hyperterm

-Baud Rate 115200, No Parity, 8 Data Bits, 1 Stop Bit

Type “Help” at the command line prompt to see a list of commands including Measure, Log, Leak Test, Purge, Setup, Status…

For some commands type Help in front of the command to get more information. Such as Help Setup, or Help Log to view or download setup information or logged data.

-SDI-12 Commands

-View and modify the CFB’s default setting via SDI-12 commands, using your data logger’s SDI-12 Interface

-Setting the Stage Level with SDI-12 Command

0XS+10.00+1! – This command sets the water level reading to 10.00 feet of water

-Changing measurement units

0XUP+4+3! – This command sets the units of water level measurement to Meters of Water (4) with 3 Right Digits resolution

See CFB Manual For a Complete List of SDI-12 Commands.

purging the orifice tube
Purging the Orifice Tube
  • 2 Setup Options for Purging
    • Auto Purge – Schedule an Orifice Line Purge at Regular Scheduled Interval
    • AutoBlockage Detection
      • If Auto Blockage Detection is Enabled the CFB Will Save Battery Life and Desiccant Life By Purging Only When a Blockage of the Orifice Line is Detected.
