GENERAL

1.1 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
be connected to a data collection platform (DCP) using the SDI-12 interface for data logging capability

Figure 1-1: Bubbler components

The system forces air at a continuous rate through an orifice line, the end of which is mounted at a
known, fixed position. A sensor measures the pressure required to maintain the air flow down the
orifice line such that bubbles emerge from its end, compares that to atmospheric pressure, and
computes the stage level (water depth). Any change in water level causes the air pressure in the
orifice line to vary resulting in updated stage levels.

FTS’ proprietary design allows for a larger orifice (18 times larger than the standard metering valve
orifice of 0.035mm). Not only does this minimize fouling of the manifold but it also allows the purge
to flush particulates throughout the entire system from the compressor valve to the orifice line end
fitting. The purge is achieved without bypassing a portion of the system, as systems which use a
metering valve must do. This results in highly accurate readings, even in environments with high
humidity or containing airborne particulates.

To maintain the integrity of the internal components, FTS suggests maintenance should be conducted
by factory trained personnel at the FTS factory.

1.2 DISPLAY AND KEYPAD

The front panel has a display and keypad which is used to view information and perform specific
actions (purge, set stage, setup, and diagnostics). The display will normally be off in power save mode.
Pressing any key will display the status screen. The arrow keys are used to navigate through the
different functions and configuration parameters.

The front panel allows the user to do the following:

 Set purge pressure
 Conduct a manual purge
 Manually bleed the tank
 Set stage
 Set stage units
 Set bubble rate
 Set averaging duration
 Set temperature units
 Set the SDI-12 address

Details of the interface and menu items are contained in Chapter 3.

1.3 CONFIGURING THE BUBBLER

The Bubbler can be configured through its front panel or through a data logger. However, certain
features, those which require a timer, can only be set through a data logger. Refer to Table 1-1.

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. If not using an Axiom Datalogger and it is desired to maintain the integrity of the
Bubbler’s SD card timestamp, this will have to be manually set every 24 hours using the Set time and date X­command ( See section 5.2 )

700-Bubbler-Man Rev 2 14 Aug 2017 Page 2/35

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.

If using a data logger other than the Axiom, configuration is done using the X-commands. Refer to
Chapter 5.

1.4 FIRMWARE UPDATES

Periodically, the Bubbler’s firmware may need to be updated. In that event, FTS will issue a
notification with instructions on how to conduct the update.

700-Bubbler-Man Rev 2 14 Aug 2017 Page 3/35

Chapter 2

INSTALLATION

2.1 PRIOR TO PROCEEDING TO THE SITE

2.1.1 EQUIPMENT

Unpack the Bubbler and conduct a visual inspection for any signs of shipping damage. If any damage
is found, contact FTS Service and Support immediately. Retain the shipping container to transport the
Bubbler to the site or to return the unit to FTS should damage have occurred during shipping.

A 3/32” head size flathead screwdriver will be required for the screws on the terminal blocks. Ensure
you bring the required tools and hardware for mounting the Bubbler in accordance with your site
characteristics.

2.2 SITE SELECTION

The Bubbler should be mounted adjacent to the body of water to be measured, typically in a
hydrology shack or gauging house. The position of the Bubbler should allow for a continuous
downward run of the orifice line to its final termination point. The water should be relatively calm and
where sediment accumulations are not likely to block the orifice.

The orifice line with a terminating orifice should be laid out into the water so that the stream ward end
will remain in a fixed position and at a depth that will not be exposed at low stage. Should the orifice

line need to be installed in an area with high currents, it should be installed in a static tube.2

2.3 MOUNTING

The Bubbler should be firmly bolted to a vertical surface using the mounting plates located on the
corners of the enclosure. 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.

It is not recommended to mount the Bubbler so that it rests on a horizontal surface
such as a table top or shelf as this can bend the orifice line permitting moisture to
accumulate and prevent the correct operation of the device.

2.4 CONNECTORS AND WIRING

When installing the Bubbler connections, do not apply power until all other connections are made.

The following connections should be made:

1. Data connections (SDI-12)

2. Desiccant assembly

3. Orifice line

4. Power

2

Refer to USGS publications TM3-A7 Stage Measurement at Gaging Stations http://pubs.usgs.gov/tm/tm3-

a7/pdf/tm3-a7.pdf and TWRI_8-A2 “Installation and Service Manual for U.S. Geological Survey Meters”
http://pubs.usgs.gov/twri/twri8a2/html/pdf.html

700-Bubbler-Man Rev 2 14 Aug 2017 Page 4/35

2.4.1 SDI-12 Connections

SDI-12 connections are made using the removable terminal block on the bottom of the Bubbler.

These connections are used to connect the Bubbler to an SDI-12 capable DCP, such as an Axiom
Datalogger.

The SDI-12 interface has connections for power (12 v), serial data, and ground. Connect the SDI-12
leads to the data logger in accordance with the manufacturer’s direction. Connect the flying leads
from the data logger to the Bubbler’s terminal strip as shown.

Insert the terminal block into the Bubbler’s connector port and secure.

Pin Description
1 12 volt line
2 Serial data line
3 Ground line

Figure 2-1: SDI-12 Connections

2.5 DESICCATOR

An external desiccator must be connected to prevent the accumulation of moisture in the compressor
manifold and throughout the system. The desiccator should be mounted close to the Bubbler to
minimize the length of the output hose. 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.

2.6 CONNECTING AND INSTALLING THE ORIFICE LINE3

The orifice line should be black polyethylene 3/8” outer diameter, 1/8” inner diameter USGS approved.
The maximum length of the line should not exceed 1000 ft. There will be an induced error caused by a
pressure drop in lines which exceed the maximum recommended length.

The orifice line should be laid out and the run established and set up before connecting it to the
Bubbler.

The run should be as straight as possible in a continuous downward path to minimize moisture
collection in catenaries. No part of the line should be lower than the line exit in the water. The run
should terminate in a calm area.

Consider enclosing the line in a protective conduit to prevent damage from animals, vandals, etc.

The orifice line should be laid out in calm water and secured so that the stream ward end with the line
outlet will remain in a fixed position and at a depth that will not be exposed at low stage. The stream
ward end should be directed pointing down.

Should the orifice line need to be installed in an area with high currents, it should be installed in a
static tube.

DO:

 Use only USGS approved line
 Install the line outlet pointed downwards

in calm water

 Ensure the line’s run is downward with no

catenaries or bows

 Ensure no part of the line’s run is lower

DO NOT:

 Face the stream ward end of the orifice

line facing upstream, downstream or
upwards

 Mount the line outlet in turbulent water

or in the wake of an obstruction (boulder,
bridge footing etc.)

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.

Fittings” on the Swagelok website. https://www.swagelok.com/downloads/webcatalogs/en/ms-13-151.pdf

700-Bubbler-Man Rev 2 14 Aug 2017 Page 7/35

1) Mark a line along the back of the nut and Bubbler

outlet. These marks will be used to return the nut to
this position.

2) Use two wrenches as shown in Step 4 of the

assembly directions to loosen the nut.

3) Once maintenance is complete, replace the nuts and

ferrules, and re-insert the line as shown in Step 1 of
the assembly instructions.

4) Using the wrenches as shown in Step 4 of the

assembly instructions, turn the nut to the marked
position. At this point, resistance will increase.
Tighten the nut slightly.

2.7 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.

IMPORTANT! If the Bubbler is sharing an external battery source with other

equipment, the combined power draw will need to be considered when calculating
the site’s power budget and power requirements.

To connect the power cable:

1) Remove the power terminal block from the port

2) Secure the power wires to the appropriate pins (positive and
negative – see Figure 2-4).

3) Connect the power cable to the power source (positive to
positive, negative to negative).

4) Re-insert and secure the power terminal block.

When the status screen is displayed, pressing the right arrow on the keypad will initiate a fresh stage
reading.

3.3.1 FAULT

The FAULT display line can only show a single fault. Possible faults are prioritized, with the
understanding that a higher priority fault is normally the cause of lower priority faults (e.g. an
apparent compressor fault is caused by a battery fault). The priority of faults (highest to lowest) is:

 BATTERY

 TEMPERATURE

 LINE_BLOCK

 LINE_HIGH

700-Bubbler-Man Rev 2 14 Aug 2017 Page 10/35

If the line becomes obstructed by silt, dirt or other debris, or water has accumulated in the line, the
line must be cleared. This is done by conducting a purge. No readings can be taken during the purge.

Input the desired pressure for the purge. The pressure range is 20-90 psi; the default setting is 90 psi.
The set purge pressure must be greater than the running tank pressure for the purge to take place. .
During a purge, the pump increases to the set purge pressure. Once the input purge pressure is
reached, the outlet valve is opened and the air is forced out until the tank pressure has dropped to 3
psi greater than the tank pressure was prior to purge. This prevents the ingress of water into the line.
Once the purge is complete, the tank pressure will equalize to the line pressure, and the bubble rate
will return to the settings prior to the purge.

To conduct a purge, select PURGE: START. Once the purge starts the screen will display
PURGE: STOP. The purge can be stopped during the process by selecting the PURGE: STOP option.

If PURGE: STOP is selected, the pump will stop, the tank pressure will decrease, and operations will
resume at previously configured settings. The increased pressure may cause the bubble size to
increase briefly until the tank pressure drops to the correct value.

If after 45 seconds of purging, the line cannot be cleared and the tank pressure is greater than 35 psi, a
compressor fault will be indicated in the status screen and the compressor will stop. The M and M1
commands will continue to be sent but will return values of -99999.0. The unit will continue to
attempt to bubble (the solenoid will continue to open and close) in the event the blockage does get
cleared and normal operations can resume.

If the tank pressure is less than 35 psi, the unit will continue bubbling at the set rate.

3.4.1 BLEEDING THE TANK

The tank pressure must be bled prior to some maintenance such as removing the orifice line or
swapping the bubbler. Once started, bleeding can be stopped by selecting the BLEED: STOP option.
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.

However, if power is not disconnected after the tank is bled and no further actions are taken,
operations will resume after 24 hours.

Normal Tank Bleed Procedure:

1) Start Bleed (bleeding will stop once tank empty)

2) Disconnect Power connector

3) Conduct maintenance

4) Replace power connector

3.5 CONFIGURING THE BUBBLER USING THE BUBBLER INTERFACE

The Set Stage and Setup menus are used to configure the Bubbler.

IMPORTANT! After configuring, synchronize the Bubbler with the data logger by

issuing the aXCON! Command (see section 5.2).

The following variables can be set using either the Bubbler’s interface or through the data logger. The
Bubbler will retain the last input configuration regardless of which method is used.

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.

MEASUREMENT UNITS

 in (Inches)
 ft (feet)
 mm (millimeters)

 cm (centimeters)
 m (meters)
 cu (custom)

HINT: When initially setting the Stage, enter the units of measurement first, and then

the desired stage value to prevent inadvertently leaving an erroneous stage height.

Explanation:

The desired stage measurement is 3.0 m. The currently entered stage measurement unit is in
feet (ft). When you enter Stage Height 3.0, the Bubbler now recognizes 3.0 ft as the stage height.
If you subsequently change the units to the desired meters (m), the stage height will be
converted to 0.914 (3.0 ft = 0.914 m).

If you do not return to the Stage function and re-enter the correct stage height, the input stage
value will remain as 0.914 m as opposed to the desired 3.0 m.

address using the Bubbler’s Setup menu, will NOT be reflected in the data logger.

If the address is changed after the Bubbler has been configured with the data logger, you must ensure
the data logger configuration is also changed to recognize the new address. If this is not done, the
data logger will not be able to communicate with the Bubbler resulting in data loss.

moisture, dust and other airborne debris which may enter the enclosure.

1) Open the Bubbler and insert the SD card in the SD slot

on the circuit board

Figure 3-7: SD card slot

2) Close the Bubbler and go to the Diagnostics sub-menu and select UPDATE. It will display the
firmware version.

It is good practice to compare the VERSION and UPDATE displays to ensure the update is to
a more current version.

3) Press the “Select/Accept” button to initiate the download. The process normally takes
approximately 45 seconds.

The display will flash while the update is downloading. When the display stops flashing, the
download is complete and the Bubbler will reset.

To operate the Bubbler with other data loggers, refer to their operator’s manuals. SDI-12 commands
for the Bubbler are found in Chapter 5.

IMPORTANT! Specific variables can be configured using the Bubbler’s user interface or

through the Axiom’s Bubbler sensor extension. The Bubbler and Datalogger will retain
the last input configuration regardless of which method is used.

The following variables can be set using either the Bubbler’s interface or through the data logger

 Set stage
 Stage units
 Bubble rate
 Temperature units
 Averaging Duration

When used with an FTS Axiom Datalogger, the date and time will be set automatically.

Note that changes made on the Bubbler’s interface will not be reflected in the Datalogger’s screens
(and vice versa) until after the Datalogger has sent the SDI-12 command relating to the specific
variable. Once the command is sent, the Datalogger recognizes the latest change and will update its
configuration accordingly.

From the Datalogger’s Home screen, select the SDI-12 icon and then the Search icon. Select OK on the
SDI Detect screen. DO NOT check the “Include alpha in search” box.

The following screen will be displayed. Note that the Address displayed will be the address set in the
Bubbler. In this example it is the default address of zero (0). Tap on the “New” field to bring you to the
Bubbler Sensor Setup.

4.1 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.

Default names: Most fields have default names which can be edited if desired by selecting the field

and then inputting the desired name using the pop-up keyboard.

In Edit mode, three icons are displayed on the bottom banner and are present in all tabs.

Read: This will send the M1 command6 and trigger a sensor reading. It will return the Measurement

Time, number of data points returned with the values taken.

OK (green checkmark): This accepts changes in ALL the tabs. Input all desired changes in all the tabs

prior to selecting OK. Once selected it saves the changes and then displays the Sensor screen.

Cancel (red X): This will cancel all the changes made in all the tabs. Tabs will revert to the previous

inputs.

4.3 STAGE TAB

Stage Name: This is the name of the data point. Stage is the default name and can be changed if

desired.

Offset Name: Input the desired name for the Stage Offset data point. The offset is calculated

automatically by the Datalogger but will only be displayed on the main Bubbler Sensor screen if
the Offset Name field is populated. See section 4.6.

Precision: This indicates the number of decimal places to which the reading will be displayed. The
maximum number is three.

Units: Select the desired units of measurement using the drop down menu. The choices are

 m (metres)
 mm (millimetres)
 cm (centimetres)
 ft (feet)
 in (inches)
 cu (custom)

Setting Custom Unit (Slope)

Select Custom to input a slope. Once Custom is selected in the drop down menu, a blank field
will appear in which the desired slope can be input.

700-Bubbler-Man Rev 2 14 Aug 2017 Page 17/35

Averaging Duration: The period of time over which the samples taken. This will be used to calculate

the displayed stage value. It takes approximately 2 seconds to take a sample. The average
duration range is from 2-60 seconds.

Bubble Rate: This determines the number of bubbles per minute which will be released. The rate can
be set from 30-120 bubbles per minute.

Interval: This is how often a measurement will be taken. It is in HH:mm:ss format.

Offset: This determines the starting time the measurement will be taken based on time after

midnight.

For example: An interval of 01:00:00 and an offset of 00:15:00 means a measurement will be
taken every hour commencing at 15 minutes after midnight (00:15:00, 01:15:00, 02:15:00, etc.).

4.4 MECHANICAL TAB

Tank Pressure Name: The default name is TankP and can be changed if desired. Units are in PSI.

700-Bubbler-Man Rev 2 14 Aug 2017 Page 18/35

4.5 PURGE TAB

Purges are conducted to clear the hose outlet of silt or debris which may be blocking it. The frequency
of the purges and the PSI used to conduct them are dependent on the environment and conditions of
the site. The Datalogger can initiate purges on a regular schedule, if the line pressure reaches a
threshold value, or under both circumstances. Purges will only take place if one or both of the options
are enabled.

Figure 4-1: Purge tab showing Scheduled and Threshold purge options selected

Scheduled Purge

For a scheduled purge, ensure the Enable Scheduled Purge checkbox is selected.

Select the desired pressure at which to conduct the purge. The pressure range is from 20-90 PSI. The
default value is 90 PSI.

Interval: The interval is how often the purge will occur and is in HH:mm:ss format. The minimum
purge interval is 10 minutes (00:10:00).

Offset: Optional. This determines the starting time the purge will commence based on time after
midnight.

For example: An interval of 24:00:00 and an offset of 10:15:00 means the purge will take place
daily (every 24 hours) at 10:15 a.m.

Purge if greater than

To conduct purges when the line pressure exceeds a threshold value, select the Purge if greater than
checkbox and input the desired threshold value.

measured values. Use the setup cog to display and edit the Bubbler Sensor Setup screen.

700-Bubbler-Man Rev 2 14 Aug 2017 Page 20/35

4.7.1 CONDUCT A MANUAL PURGE

Purge Now: Select this to conduct a purge. Input the desired pressure. The Purge PSI will remain at

this value until changed.

4.7.2 SET STAGE AND CALCULATE/CLEAR OFFSET

Set Stage and Clear Offset enable the user to set and clear the stage offset value. They are present
when a Stage variable is configured on the Stage tab. Once the stage is set, the Datalogger will
automatically calculate the Stage Offset. The Stage Offset will be displayed as a data point if the Offset
Name field was populated in the Stage Tab.

Set Stage

Once the sensor has been configured and is operating, the Set Stage and Clear Offset buttons can be
used. They are present only if a stage variable has been configured on the Stage tab.

There are two methods available for setting the stage offset in the Datalogger depending on if the
staff gauge reading is known or not. If it is known use the Set Stage button. If it is not known, use the
Polled feature.

Staff Gauge Reading Known

If the staff gauge reading is known, press Set Stage, enter the staff gauge value, and confirm the
changes.

700-Bubbler-Man Rev 2 14 Aug 2017 Page 21/35

The Datalogger calculates the appropriate stage offset from the current stage sensor reading.

Polling

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.

The user can select the Polled checkbox and then press Set Stage to begin a series of Bubbler
readings while the user checks the staff gauge reading. After checking the staff gauge reading and
returning to the Datalogger, the user can select the appropriate time stamped Bubbler reading and
then enter the staff gauge value so that the Datalogger can calculate the appropriate stage offset.

The stage reported on the Display screen and on the Stage Offset Tool screen will use the units that
the user has selected during the setup process (If the FTS pressure transducer (SDI-PT) is being used
with the Axiom, the SDI-PT calculation (SDI-PT calc) will be applied if enabled during that sensor’s
setup).

The steps to set up polling follow:

1. Tap the Polled box, and then select Set
Stage.

700-Bubbler-Man Rev 2 14 Aug 2017 Page 22/35

2. The Stage Offset Tool screen is displayed.
Enter the desired Interval and Timeout
times.

Interval is the polling interval and Timeout is
the period of time over which polling will take
place. The Poll Sample Size refers to how
many readings will be averaged per interval.

3. Synchronize your timepiece to the
Datalogger and select Start.

The screen is displayed in view only mode
and polling commences. Polling values will
be displayed until the Stop button is selected.

4. Go read the staff gauge. Note the time and
the Staff Gauge value.

5. When you return to the Datalogger select
STOP, scroll through the stage sensor
readings and tap on the time that
corresponds to your reading of the staff
gauge. Press Select.

6. The Enter Staff Gauge Value screen appears.
Enter the observed value and confirm.

700-Bubbler-Man Rev 2 14 Aug 2017 Page 23/35

7. Confirm the new Stage Settings

8. The new Stage Offset will be calculated.

9. De-select the Polled box.

5.2 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. Likewise, the first character of a response is also the address
character.

Some commands can be used to either view a parameter (“get”) or input a parameter (“set”). Set
commands use an optional parameter P or a float parameter P.p. To “set” a value, the P or P.p should
be replaced with the desired numeral(s). If the optional parameter is not used, it is a “get” command
and will return the previously set value. .

5.2.1 Required Formatting Elements

In order for X commands to be valid, the following format conditions must be met:

 the X must be capitalized; character case is not important for any other element

 there must be no spaces within the command



in “set” commands, the ’P or P.p’ or should be replaced with the desired numerals.

2) Ensure orifice is free from larger obstructions/blockages

3) Inspect along length of line for crimps, compressed areas.

4) May have to bleed tank, cut power and remove/replace line

B.3.1 MANAGING HEALTH STATUS INDICATORS

If using an Axiom Datalogger, health status indicators of 1, 2 and 4 (and by default 3 and 7) are
managed by the Datalogger. When one of the aforementioned indicators is detected, the Axiom
Datalogger will automatically send the required X-command to rectify the situation. If your Axiom is
continuously showing a health status indicator of 7, that indicates a failure of the Datalogger to fully
communicate with the Bubbler and a site visit is required to determine the cause.

If using a non-AXIOM data logger the most common health status indicator will be 4. A “4” means the
Bubbler is still operating normally, but the bubbler’s SD card9’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.

9

The SD card is used by FTS factory personnel for troubleshooting.

700-Bubbler-Man Rev 2 14 Aug 2017 Page 32/35

Also, for non-AXIOM data loggers, if any configuration change was made or the Bubbler was rebooted
(after a power cycle, for example), the aXCON! command should be issued to clear those health status
indicators.

B.3.2 DETERMINING MULTIPLE HEALTH STATUS INDICATORS

1) Value (a) is returned from the get data (aD!) command in the health status field. Find the value
(b) in the Health Status Table that is closest to but less than (a). Value (b) indicates the first health
status indicator.

2) Subtract (b) from (a): a-b= c

3) Find the value (d) in the Health Status Table that is closest to but less than (c). Value (d) indicates
the second health status indicator.

4) Subtract (d) from (c): c-d = (e)

5) Find the value (f) in the Health Status Table that is closest to but less than (e). Value (f) indicates the
third health status indicator.

6) Continue in this fashion until the difference of the two values = 0

Example: 0D0! +5.23+0+23.5+7-1.3+20+30+12.5+263

1) Value (a) = 263. Value (b) = 256 = Battery out of range error

2) 263-256 = 7. Health status value closest to 7is 4= Needs time and time set

3) 7 – 4 = 3 Health status value closest to 3 is 2 = the Bubbler has rebooted

4) 3-2 = 1 Health status Value closest to 1 is 1 = data logger and Bubbler are out of
Synchronization

5) 1-1 = 0 No further indicators
