  • Page 6: Introduction

    Introduction The Sutron Accubar ® Continuous Flow (CF) Bubble Gauge/Recorder (part number 56-0133-25-1) s a self- contained, precision device for measuring water levels. The device combines into a single package a pump, tank, manifold, control board, front panel (display and keypad), Accubar sensor, SDI-12 and RS232 interfaces, and enclosure for the purpose of measuring water levels using long established bubble gauge principles.

  • Page 7: Dual Orifice Bubbler

    Dual Orifice Bubbler The Sutron Accubar ® Constant Flow (CF) Dual Orifice Bubble Gauge/Recorder (part numbers 56-0134-25- 1, -2 and -3) is an enhanced version that is capable of providing redundant measurements, measuring water level in two separate bodies of water, accurately measuring water density, or providing an extended range of water level measurement.

  • Page 13: Setup And Operation

    Bubble Rate The bubble rate is the measure of the amount of air going down the orifice line per unit of time. The Sutron Bubbler supports two units for bubble rate: Bubbles per minute (BPM) and Standard Cubic Centimeters per Minute (SCCM).

  • Page 14: Purge

    Pump Run Time The Bubbler tracks the cumulative pump on time. That is the total amount of time that the pump has been running. It is possible to reset the pump run time. Both the single and the Dual Orifice Bubbler are equipped with a single pump. The Dual Orifice Bubbler has two tanks and operates a valve in order to select which tank is being filled by the pump.

  • Page 15: Blockage Detection

    Sutron provides a cap with each unit that can be used to cap the outlet for the leak test. When the leak test completes, the system will display a status indicating whether the unit has passed or failed the leak test along with a score.

  • Page 16: Starting The Bubbler

    A Dual Orifice Bubbler can run leak tests on each line independently. Leak test information for each line is stored separately. To start a leak test, use Diagnostic > Leak Test, or LEAK TEST via command line. Starting the Bubbler The Bubbler starts operating as soon as power is applied.

The CF Bubbler Accubar features an autozero ability that eliminates the errors due to a drift in zero resulting in more accurate water level readings. The Bubbler will automatically autozero the Accubar at the end of a purge. The autozero will take approximately half a minute to complete.

The 3/8” tubing provided by Sutron can be installed directly on the ground, buried in the ground or in a conduit. When running the tube to the water, try to ensure that the line is run with a continuous downward slope.

    Leaks inside the Bubbler can be a source of inaccuracy and/or excessive pumping and use of desiccant. To check for leaks, you must cap the outlet or orifice and run the built-in leak test routine. Sutron provides a cap with each unit that can be used to cap the outlet for the leak test. When the leak test completes, the system will display a status indicating whether the unit has passed or failed the leak test along with a score.
