Environmental Compliance
Waste Electrical and Electronic Equipment (WEEE) Directive
Panametrics is an active participant in Europe’s Waste Electrical and Electronic Equipment (WEEE) take-back
initiative, directive 2012/19/EU.
The equipment that you bought has required the extraction and use of natural resources for its production. It may
contain hazardous substances that could impact health and the environment.
In order to avoid the dissemination of those substances in our environment and to diminish the pressure on the
natural resources, we encourage you to use the appropriate take-back systems. Those systems will reuse or recycle
most of the materials of your end life equipment in a sound way.
The crossed-out wheeled bin symbol invites you to use those systems.
If you need more information on the collection, reuse and recycling systems, please contact your local or regional
waste administration.

Programming Site Data
Introduction
The 2-Channel Model GS868 flowmeter cannot provide accurate flow rate measurements for either channel until the
instrument has been properly installed, the channel has been activated, and the basic system and pipe parameters
have been programmed into the meter. See the Startup Guide for detailed instructions on performing these tasks.
After completing the installation, proceed with this chapter to program the Model GS868’s advanced features.
Four submenus within the User Program provide access to the various programmable features of the Model GS868.
Step-by-step programming instructions for each submenu are presented in this chapter. Refer to the appropriate
section for a discussion of the following User Program submenus:
•
CH1/CH2 - use this submenu to activate a channel and to enter the basic setup parameters for that channel.
•
GLOBL - use this submenu to enter global meter parameters (i.e., clock, system, input/output, communications
and security), which apply to both channels.
•
SAVE - use this submenu to store both channel and global data in the meter’s memory, as a site file.
•
RECLL - use this submenu to recall and activate a stored site file.
Note:
It is not required that both channels of a 2-Channel Model GS868 be installed. The second channel connector
may simply be left vacant for future expansion.
As an aid in following the programming instructions, a complete set of menu maps for the User Program is included
in Appendix A, Menu Maps. The specific figure numbers will be referenced throughout this chapter, as required.
Note:
In the menu map drawings, plain text represents prompt area messages and boxed text represents option
bar choices. Fx represents a function key to select an option bar choice.

Chapter 1. Programming Site Data
Programming of the ACTIV, SYSTM (CH1 and GLOBL) and PIPE submenus is necessary for operation of the Model
GS868. Failure to accurately enter all of the required information will result in unreliable flow rate data. Therefore, be
sure to complete at least the sections of this chapter pertaining to those three submenus.
Because it is so essential, instructions for programming the ACTIV, SYSTM (CH1 and GLOBL) and PIPE
submenus are also included in the Startup Guide. If that programming has already been completed, skip the
corresponding sections of this chapter.
Note:
Except for the three submenus noted above, it is not necessary to program the Model GS868 flowmeter in any
particular order. Therefore, the sections of this chapter need not be completed in sequence. Proceed immediately to
any section of interest.

:As indicated in the above prompt, the Model GS868 flowmeter can take measurements in two different ways:
•
•
Skan is a low resolution technique for locating the acoustic signal and for high velocity measurements. It is more
robust in a noisy environment than the Measure technique.
Measure is a more precise technique best used for low velocity measurements.
If Skan is selected at the next prompt, the instrument uses this technique exclusively. However, if S/M is selected, the
meter uses Skan to find the acoustic signal and then tries to use the Measure technique for a more precise
measurement.
Note:
To change the Skan and Measure parameters, see the SIGNL submenu section on page 16.

MODBUS Register Map
When equipped with the optional MODBUS output card, the GS868 flow transmitter can send flow data and
diagnostic information to a flow computer (or SCADA) serially, using a Gould-type RTU protocol. In this case, only the
MODBUS function command, 3 (read multiple registers), 6 (write multiple registers) is valid. The format for the data
exchange is as follows:
•
The send command (initiated by the host flow computer or controller) comes in the form:
[time delimiter]<Addr><3><First Register MSB>
<First Register LSB><Register Count MSB>
<Register Count LSB><CRC Low><CRC High>[time delimiter]
•
The response (initiated by the host flow computer or controller) comes in the form:
[time delimiter]<Addr><3><Byte count><Data.........>
<CRC Low><CRC High>[time delimiter]
The format for the returned data types is as follows:
•
Integer (16 bit Integer) <MSB><LSB>
1 Register - 16 bit integer
•
Integer (32 bit IntegerI) <MSB><LSB><LSB><LSB>
2 Register - 32 bit integer
•
Floating Point (FP) <EXP><MAN><MAN><MAN>
2 Registers - 32 bit IEEE floating point number
To request specific parameters from the GS868 via the MODBUS, the control system must enter the appropriate
register number. Only registers 1 through 90 are available for MODBUS communications, while registers 508 through
512 are used by the GS868 to store the MODBUS parameters. For details, see Table 12 on page 32.

Activating Security
In order to prevent unauthorized tampering with the flowmeter’s programming, the Model GS868 is equipped with a
security feature that locks out the following menus:
•
•
•
•
Program Menu [PROG]
Calibration Menu [CAL]
Log Menu [LOG]
Clear Menu [CLR]
When the system is locked, access to the above menus will be denied unless the correct password is entered. The
Model GS868 is shipped with a default password, which is given later in this section. For increased security, the
default password should be changed.
DigitalFlow™ GS868 Programming Manual (2-Channel)

1.8.7
Saving Site Data
The currently programmed site data may be stored in the Model GS868’s non-volatile memory by saving it as a site
file. Up to ten site file names, consisting of up to five characters each, may be stored at any given time. To enter the
SAVE menu, press [F4] at the initial User Program screen. Refer to Figure 13 on page 85.
1.
Enter a new site file name and press [ENT], or use the ], ] and [F1]-[F4] keys to select and overwrite an
existing site file.
Note:
The option bar will show only as many choices as there are existing site files.
If ten site files are already stored in memory, an existing site file must be deleted before a new site file name can be
assigned. See Chapter 5, Clearing Data, for details.
When a site file is stored in memory, it becomes the active site file until another site file is created or retrieved. (See
the next section for instructions on retrieving a site file.) To verify that the site file has been saved, use the ] key to
scroll back to the SITE NAME prompt and see if the name appears on the option bar (use the ] and ] keys to
scroll through the list, if necessary). Whenever a new site file name is saved, it is automatically assigned to the next
available function key.
IMPORTANT: The CLOCK and I/O data is not saved with the site file, while the SYSTM and COMM data is saved with the
site file.
2.
Use the ] and ] and [F1]-[F4] keys to select another menu, or press [EXIT] to leave the User Program and
return to measurement mode.
1.8.8
Recalling a Site
Any site file currently stored in the Model GS868’s non-volatile memory may be recalled at any time. Up to ten site file
names, consisting of up to five characters each, may be stored at any given time. To enter the RECLL menu, press [?
and [F1] at the initial User Program screen.
1.
Use the ], ] and [F1]-[F4] keys to select and recall an existing site file.
Note:
The option bar shows only as many choices as there are existing site files. The files are listed in chronological
order by creation date.
Upon recall, the selected site file becomes active and all of its programmed parameters become current.
IMPORTANT: The CLOCK and I/O data is not recalled with the site file, while the SYSTM and COMM data is recalled
with the site file.
Note:
If you have loaded a site file into a GS868, but the option cards are not in the same slots or programmed the
same way as when the site file was first saved, the GS868 displays a warning to review slot information. This
display does not mean that the option cards have lost their program information!
Use the ] and ] and [F1]-[F4] keys to select another menu, or press [EXIT] to leave the User Program and
return to measurement mode.

At any given time, 120 data points will be shown on the GRAPH screen. The cursor, which is displayed as a vertical line
that extends the full height of the graph window, can be used to select any one of these data points.
The typical screen shown above is for a Velocity vs. Time graph with only the positive y-axis displayed. The
measurement parameter (VEL) is shown to the left of the y-axis and there is a message line below the graph that
initially indicates the starting date and time of the graphed data. Notice that most of the locator bar has been
replaced by a status line in standard video that shows the value, units and time of the measurement at the current
cursor location. However, there is still an inverse video pointer at the far right of this line to indicate that additional
option bar choices are available.
Note:
The date in the message line includes only the day and the month (not the year), and the times in the status
line and the message line includes only the hours and minutes (not the seconds).
Because the times displayed in the GRAPH format are in whole minutes only, movement of the cursor may not result
in a visible change in the posted times. For example, if a TIME INCREMENT of 30 seconds has been programmed, two
presses of either cursor movement key will be required to change the displayed time by one minute.

Chapter 3. Logging Data
3.1
Introduction
This chapter explains how to use the Model GS868’s data logging capability. The LOG menu, which is accessed by
pressing the [LOG] key on the keypad, is divided into four submenus:
•
•
•
•
STD - used to log up to three of the available measurement data parameters
MEM - used to check the data logger memory to determine if the specified log will exceed the available memory
STOP - used to terminate current data logging activity
ERROR - used to log any generated error messages.
Up to twenty standard or error log files may be created and stored in battery-backed memory. Each log file contains
up to three measurement parameters, the log start time and date, the log end time and date, the time interval
between updates, and any error messages. Error logs record data only when an error message is generated.
The Model GS868 allocates up to 120 pages of memory, each of which can contain up to 120 records, for data logging.
Each page is assigned a header, to distinguish one page from another. The header contains the log title, start date
and time, end date and time, and the time increment. Each record contains the date and time of the measurement
and the values for the three logged parameters.
Note:
Each log file uses at least one page of memory, and the same page can not be shared by two different logs.
Since a fixed amount of memory is allocated for data logging, the number of active logs, the log time increments,
and the length of the log runs will all affect how much memory is available for additional logging. For example, a log
that updates every 5 seconds will use more memory than a log that updates every 6 minutes, assuming that they
both run for the same length of time.
After a log file has been created, it may be displayed, printed, cleared or uploaded to a personal computer. Refer to
the appropriate chapters of this manual for specific instructions.
Refer to Figure 17 on page 89 in Appendix A, Menu Maps, and proceed to the appropriate section for the desired LOG
submenu. Each submenu may be followed in the sequence shown or the ] and ] keys may be used to scroll
through the prompts.

30sec, 1min, 3min, 6min, 12min, 30min and 60 min.
The time increment is the frequency at which the Model GS868 takes and records data measurements. If any reading
takes longer than the programmed time increment, the log is filled in with the next consecutive reading. For example,
assume that a velocity value of 3 ft/sec is recorded at 12:00:00 in a log with a time increment of five seconds. If the
next reading is 8 ft/sec and it takes the meter 12 seconds to read this value, then both of the missed readings
(12:00:05 and 12:00:10) will be filled in with the 8 ft/sec value.
Procedure Options
You have completed entering data for a standard log. You can now do one of the following:
•
Use ] and ] to review the previous menu prompts.
•
Press [F1]-[F4] to select one of the LOG submenus.
•

3.3
Checking the Memory
Use the MEM submenu to verify that the available log memory is sufficient for the desired log. If the expected amount
of logged data will exceed the remaining memory capacity, the Model GS868 suggests that some old logs be
cleared to make room for the new log.
Press the appropriate side of the [SCREEN] key to activate the desired pane of the display screen, and complete the
following steps:
1.
2.
3.
To access the Log Menu, press the [LOG] key.
a.
If you have activated the security feature (see Chapter 1, Programming Site Data, page 33 for details), enter the
assigned password and press [ENT].
Press [F2] = MEM.
After noting the information, press [ENT] to return to the main Log Menu screen.
The MEM screen lists the number of remaining unused memory pages out of the total number of 120 available pages.
Also, the number of pages expected to be used by all currently programmed logs is given. If the number of pending
pages exceeds the number of free pages, additional memory may be made available by clearing some old logs (see
Chapter 5, Clearing Data).
If it is undesirable to delete old logs to free up additional memory, the number of pages pending may be reduced by
altering the parameters of one or more of the currently active logs. For example, either increasing the time increment
or decreasing the total logging time will reduce the memory requirements for a log file. Use the following equations
to calculate the number of pages used by a log:
length of log
number of records = --------------------------time increment
number of records
number of pages = --------------------------------120
Consider a log that is set to run for 24 hours with a time increment of 3 minutes. From Equation 3-1, the number of
records = (24 x 60)/3 = 480 records. Then, from Equation 3-2 above, the number of pages = 480/120 = 4 pages. Thus,
at least four pages of memory must be available for this log to run to completion. Notice that increasing the time
increment to 6 minutes or decreasing the length of the log to 12 hours would reduce the memory requirement to only
2 pages.

Introduction
The Model GS868 flowmeter has the capability to print any of the data stored in its memory via the built-in RS232
communications port. In order to use the function, the RS232 port must be connected to a printer with a serial port
input. A printer with a parallel port input may be used with a third-party serial-to-parallel adapter.
Note:
See Chapter 1, Installation, of the Startup Guide for instructions on wiring the RS232 port. For additional

Introduction
The Model GS868 flowmeter is equipped with a standard RS232 serial interface. By using this interface, any log files
stored in the GS868’s memory may be easily uploaded to a personal computer. In order to accomplish this, the
following steps must be completed:
•
Connect the GS868 to the personal computer
•
Check the GS868 baud rate setting
•
Set up the personal computer’s terminal software
•
Transfer the log files to the personal computer.
6.2
Wiring the RS232 Interface
The first step is to connect the built-in RS232 port in the GS868 to one of the serial ports (COM1 or COM2) on the
personal computer. Table 26 below lists the standard cables available from the factory for this purpose.

Optional RS485 Serial Interface
Although the standard RS232 serial interface included with the Model GS868 is adequate for most applications,
Panametrics offers an optional RS485 serial interface upgrade for special situations. The Model GS868 is easily
modified to provide RS485 communications, and this section describes the wiring and use of the special RS232 to
RS485 converter.
IMPORTANT: This section refers to the PC communications port (labelled “RS232” on the main board). If you have a
MODBUS card installed, the terminal block on that card will always be RS485. The MODBUS card only
sends MODBUS data and cannot be used to set up the GS868. IDM communication always passes via
the RS232 port described here.
Note:
For compliance with the European Union’s Low Voltage Directive, this unit requires an external power
disconnect device such as a switch or circuit breaker. The disconnect device must be marked as such,
clearly visible, directly accessible, and located within 1.8 m (6 ft) of the electronics console.
6.5.1
Interface Converter Mounting
A special bracket containing the serial interface converter and a three-terminal barrier strip is mounted inside the
Model GS868, just below the RS232 terminal block (see Figure 9 below). The standard RS232 terminal block is wired to
the input of the serial interface converter, and the RS485 output of the serial interface converter is wired to the barrier
strip.

Point-To-Point Wiring
Note:
For compliance with the European Union’s Low Voltage Directive, a transparent plastic shroud protects the
electrical connections. The shroud must remain in place, except while wiring the unit. Reinstall the shroud
after the wiring has been completed.
Standard factory wiring of the RS485 serial interface is configured for point-to-point wiring. That is, a single Model
GS868 may be wired directly to a single personal computer. To connect the RS485 serial interface, refer to Figure 9 on
page 75 and complete the following steps:
DigitalFlow™ GS868 Programming Manual (2-Channel)

Chapter 6. Serial Communications
6.5.3
Multi-Point Wiring
The standard point-to-point wiring configuration for the serial interface converter may be modified to permit the use
of a multi-point wiring arrangement. In a multi-point RS485 system, one flowmeter (the master) is connected to the
personal computer, while a number of additional flowmeters (the slaves) are chained together and connected to the
master flowmeter. In order to implement such a system, the DIP switch settings inside each serial interface converter
must be changed.
IMPORTANT: The serial interface converter in the last slave unit in the chain should not be reconfigured.
6.5.3.1
Reconfiguring a Serial Interface Converter
To reconfigure a serial interface converter for multi-point wiring, complete the following steps:
1.
Disconnect the main power to the electronics console and open the cover.
WARNING! Dangerous voltages exist within the electronics console. Do not perform any wiring
operations until the main power to the unit has been disconnected.
2.
Remove the clear plastic shroud that covers the electrical connectors.
4.
Loosen the two screws that fasten the DB9 connector to the mounting bracket, and remove the serial interface
converter from the bracket.
3.
5.
Remove the serial interface converter mounting bracket by removing the standoff located just below the RS232
terminal block and the grounding screw to its left (see Figure 9 on page 75).
Use a small screwdriver to pry open the plastic case of the serial interface converter, as shown in Figure 10 on
page 78.
The serial interface converter contains a main printed circuit board and a daughter printed circuit board. The
daughter board has a small terminal block attached to it and the main board has a DIP switch (SW1) mounted near
the center of the board.
6.
Locate the switch assembly on the main board, and move the switch in position 1 from ON to OFF. The standard
ON state for this switch is for point-to-point operation, while the OFF state is needed for multi-point operation.

Appendix C. Programming with PanaView
C.3
Introduction
The PanaView™ graphical user interface offers interactive communications between Windows-based PCs and
Panametrics instruments compatible with the company’s IDM protocol, such as the GS868 ultrasonic gas flowmeter.
PanaView is compatible with 32-bit Windows operating systems such as Windows 98SE, NT 4.0 (with Service Pack 6),
2000, XP and ME. With PanaView, you can:
•
load and save site file data
•
create and save graph and log files
•
display text output and graphs of live measurement data
•
create custom templates for displaying text, graph and log data
•
interface with multiple Panametrics instruments.
This document focuses on particular applications suitable for the GS868. For general PanaView applications such as
creating graph and log files, displaying live measurement data, and creating custom templates, please refer to the
general PanaView User’s Manual (910-211).
C.4
Wiring the RS232 Interface
All IDM-protocol instruments utilize an RS232 interface to communicate with a PC. For details on wiring your RS232
interface, please refer to the Installation chapter of your instrument’s User’s Manual, and to the document EIA-RS
Serial Communications (916-054).
DigitalFlow™ GS868 Programming Manual (2-Channel)
95
C.5
Setting Up the Communications Port
Use the steps below to establish communications with the GS868.
1.
2.
3.
Open the “New Meter Browser” window and expand the network tree. Then, highlight the My Computer(Name)
branch by clicking on it.
Pull down the “Edit” menu by clicking on it in the menu bar.
Click on the “New” menu option to select it, and a submenu opens with two choices on it (see Figure 18 below).
Figure 18: The Edit Menu
96
DigitalFlow™ GS868 Programming Manual (2-Channel)
4.
Click on the “Communications Port” option to select it. The Setup Communications screen appears similar to
Figure 19 below.
Figure 19: Setup Communications Screen
Open the Protocol menu (the first of the drop-down menus) and click on IDM.
Open the COM Port Type menu and click on the desired type (or on TCP/IP, if the GS868 is using an Ethernet connection).
Note: If you select TCP/IP, the menu changes. Proceed to the next page.
5.
6.
7.
Select any suitable available baud rate. A baud rate of 19,200 is appropriate for almost all applications. However,
if you experience periodic communication reliability problems, you may wish to consider lowering the baud rate
on your instrument and in PanaView.
IMPORTANT: Be sure all the communications port settings match those made in setting up the meter’s serial port.
8.
Click [OK] to complete data entry.
DigitalFlow™ GS868 Programming Manual (2-Channel)
97
C.5.1 Setting up Ethernet Communications
If you have selected TCP/IP in step 6 on the previous page, the Setup Communications window appears similar to
Figure 20 below.
Figure 20: Setup Communications for TCP/IP
Type in the desired Name and Timeout (in milliseconds).
In the IP Address text box, enter the IP address. If the IP address is unknown, run the Device Discovery software utility. All units found will be identified by their MAC address and the assigned IP address. In the Port Number box,
enter 2101 (the default value).
3. Click [OK] to complete data entry.
IMPORTANT: If you are using Ethernet communications, be sure the GS868 is set up with the default
communications parameters: 9600 baud, no parity, no handshaking, 8 data bits and 1 stop bit. The
port number must match the “Enable Raw TCP access using TCP Port” assignment shown under the
Device Discovery “TCP Server Settings” menu (Configuration>Serial Ports>Port).
1.
2.
98
DigitalFlow™ GS868 Programming Manual (2-Channel)
C.6
Adding the GS868
To add the GS868 on the IDM-configured communications port, complete the following steps:
1.
2.
Highlight the communication port to which the meter will be added by clicking on it, and then open the “Edit”
menu on the menu bar (if the communication port is not highlighted first, the “New Meter” option is not active in
the “Edit” menu).
Click on the “New” option in the “Edit” menu (see Figure 21 below).
Figure 21: “New” Option in the “Edit” Menu
3.
4.
After clicking on the “New” option, the “Meter” menu option appears. Click on this option to select it.
The “New IDM Meter” screen (shown in Figure 22 below) opens. Enter the Network ID number for the meter, and
click [OK].
Figure 22: New IDM Meter Screen
IMPORTANT:
The Network ID number must match the Network ID programmed in the meter’s Communications
