  • Page 5: Introduction

    Introduction The 5600-0131 and 56-0131 ACCUBUBBLE™ Self Contained Bubbler System utilizes a solid-state pressure transducer suitable for data collection and monitoring applications. The ACCUBUBBLE™ system has been designed with the following features to operate in a wide range of applications: High silting Purges before every measurement by default.

  • Page 6: Initial Setup Guide

    Initial Setup Guide A few quick comments first. The AccuBubble utilizes the SDI-12 command syntax. This means that all commands are case sensitive and are immediately responded to if recognized. If they are not recognized, there is no response. The first character of every command is the address of the unit. By default this is 0 (zero).

  • Page 11: Setup And Operation

    To issue commands to the ACCUBUBBLE via SDI-12, you will need to connect it to a data recorder, such as a Sutron 8200, 8210, or 8400 which is capable of issuing standard and extended SDI-12 commands. Follow the instructions in Sections 2 and 3 in order to make these connections.

  • Page 12: Verifying The Address And Operation

    The ACCUBUBBLE will respond with an identifying message when it receives the send identification command, I. The format of the command is: Where a is the address for the ACCUBUBBLE.

    1.0, version 1.1, version 1.2, and version 1.3 plus some extended commands defined by Sutron. All commands start with a single-character address and end in an exclamation point. The address is a single character with values 0 to 9, A to Z, and a to z. Values are entered in the form of a polarity sign (+ or −) followed by up to seven digits, including a decimal point.

  • Page 14: Making A Measurement

    Making a Measurement There are four classes of measurement commands which will be referred to as M commands (Measurement Commands), C commands (Concurrent Measurement Commands), MC commands (Measurement commands with CRC-16), and CC commands (Concurrent Measurement Commands with CRC-16). Concurrent measurement commands are new to version 1.2 of the SDI-12 specification.

    Similarly, the slope and offset can be set to any values that will produce the desired units. NOTE: Remember that both an XUU and an XUP command are required for the ACCUBUBBLE to report in user-defined units.

  • Page 22: Field Calibration

    Field Calibration The ACCUBUBBLE may have a change in the calibration over time. The most common change is a change in sensor zero (value read when the pressure is 0). The ACCUBUBBLE has two commands that can be used to adjust for this change in zero. The XE command allows direct setting of an offset which will be added to the measurement to compensate for this drift: where o is adjustment value with units u.

    This command also supports setting the step rate for the quadrature output. The factory default for the step rate is 100 steps per second. This corresponds to the maximum step rate for the Sutron 5600-0126-1 Chart Drive. This means that if the ACCUBUBBLE detected a one foot change, then the output would be ramped at the rate of 0.1 foot per second for 10 seconds (1000 steps divided by...

    For this example the pump would only have 13% of the duty cycle it would have from purging every reading, an 87% reduction in its power consumption. As can be seen from a typical on_time of 0.5 seconds versus a typical purge time of 10 seconds, substantial power savings can be achieved when frequent measurements are occurring.
