    GENERAL INTRODUCTION The FTS Bubbler is an SDI-12 user configurable system for accurately measuring water stage in streams and reservoirs using pressure differentials. It is a self-contained, sealed system that includes an air compressor, control electronics and a high accuracy pressure sensor for measuring water levels. It can...

    Bubbler or the data logger. This sets the Bubbler’s date and time which is used on the time stamp of the Bubbler’s SD card. It does not affect the time stamp of sent data or the timing of scheduled events as those are controlled by the data logger and the telemetry in use.

    The Set Stage and Setup sub-menus on the Bubbler’s interface are used to configure the Bubbler. Refer to Chapter 3 for details. If the Bubbler is used with an FTS Axiom Datalogger, configuration is done through the Bubbler sensor extension. See Chapter 4 for details.

  • Page 8: Chapter 2 Installation

    The connectors and outlets should be pointing down. The bottom of the Bubbler should be free of obstruction so the orifice line has a free downward run. Ensure the orifice line is not bent or crimped.

  • Page 9: Sdi-12 Connections

    Ensure there are no kinks or bends in the output hose. Connect the output hose from the desiccator to the inlet fitting on the Bubbler. Secure both ends of the hose with a hose clamp. Follow the manufacturer’s directions with respect to handling, mounting, maintenance, and disposal of the desiccator and desiccant.

     than the line outlet Once the orifice line run is securely laid out, connect the orifice line to the Bubbler outlet (refer to Figure 2-3) and secure it with the provided Swagelok® fitting. For a detailed explanation of the installation of an orifice line and static tube, refer to USGS publications: TWRI_8-A2: Craig, J.D, 1983, “Installation and service manual for U.

    2) Screw the nut on until finger tight. 3) Mark the nut at the 6 o’clock position. 4) Hold the Bubbler outlet steady with a wrench, and use another wrench to tighten the nut one and a quarter turns (pass the 6 o’clock position once and stop at the 9 o’clock position).

  • Page 12: Power Connections

    Tighten the nut slightly. POWER CONNECTIONS The Bubbler requires a dedicated +12V power source to operate. This is normally supplied by an external lead-acid battery. Although the Datalogger supplies some power through the SDI port, it is only enough to view and operate the Bubbler’s screen. It is insufficient to run the compressor.

    Press the Select/Accept to save the changes. STATUS SCREEN The Bubbler’s status screen will display the site identification or any faults, the latest stage measurement, the calculated offset and the tank PSI. Note that if a custom slope was used to calculate the stage, the displayed unit of measurement will be “cu”...

    If selected, the compressor will recharge the tank and operations will recommence. Once the tank is bled, the power connector to the Bubbler should be removed until maintenance is completed. Once maintenance is completed and power is re-established, operations will recommence.

    Figure 3-4: Set Stage sub-menu Stage – Use the arrows to input the stage height. The Bubbler will use this value to calculate the offset which will be displayed on the Status Screen. Units – Use the up and down arrows to select the measurement units. The displayed Stage value will automatically be converted to the equivalent stage value in the newly entered measurement unit.

    SETUP GENERAL INFORMATION Each of the field names created in the Bubbler Sensor Setup tabs responds to a data point which will be displayed on the Bubbler’s summary screen. Once a data point is created it will be available for other functions such as Logging, Current Conditions, Processes, etc.

  • Page 26 The polling option is meant as a temporary measure to confirm Bubbler operations and any data collected during the polling will not be recorded by the Datalogger. It will also not affect the Bubbler Setup values. That is to say, once polling is stopped, interval values will revert to those originally input in the Bubbler Setup Screen.

    EXTENDED (X) COMMANDS In addition to the standard set of commands, the FTS Bubbler has an extension of custom SDI -12 commands called X commands that access specific features of the sensor. The format of X commands follows the requirement for standard SDI-12 commands in that the first character of every command must be a sensor address which is then followed by the X command and terminated by an exclamation mark.

    Bubbler is still operating normally, but the bubbler’s SD card ’s time stamp will not be accurate. If your data logger can be programmed to set the Bubbler’s date and time every 24 hours (as the Axiom does), the appearance of this indicator can be mitigated.
