Preface
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/EC.
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.

Using the Keypad
The Model DF868 keypad contains 39 keys, that are labeled with their primary (unshifted) functions. In addition,
pressing the red [SHIFT] key will access the secondary functions assigned to most of the keys.
The complete keypad is illustrated in Figure 1 and a detailed description of both the unshifted and shifted functions
for each of the 39 keys is listed in Table 1 on page 2.
Note:
Only the [SHIFT] key and the eight [Fx] keys have no shifted function.

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.
Note:
Because it is so essential, instructions for programming the ACTIV, SYSTM and PIPE submenus are also
included in the Startup Guide. If that programming has already been completed, those sections of this
chapter may be skipped.
Except for the three submenus noted above, it is not necessary to program the Model DF868 flowmeter in any
particular order. Therefore, the sections of this chapter need not be completed in sequence. Proceed immediately to
any section of interest.

Note:
The current status of the meter is displayed in the bottom line of the prompt area.
The Model DF868 flowmeter can take measurements in two different ways:
•
The Correlation Transit-Time™ technique uses a pair of transducers (either wetted or clamp-on) with each
transducer alternately sending and receiving coded ultrasonic signals through the fluid. When the fluid is flowing,
signal transit time in the downstream direction is shorter than in the upstream direction; the difference between
these transit times is proportional to the flow velocity. The DF868 measures this very small time difference and,
using various digital signal processing techniques combined with programmed pipe parameters, determines
the flow rate and direction.
•
The TransFlection® technique uses two transducers. One transducer shoots thousands of grouped ultrasonic
pulses in very rapid succession. The pulses bounce off “scatterers” in the liquid (bubbles, solids, or liquid droplets)
and are reflected back to the other transducer. Each received pulse group receives a “snapshot” of the flow. By
comparing all snapshots and averaging out objects that do not appear to move with the flow, the DF868 can
determine flow rate and direction.
Note:
If a customer has not ordered the DF868 with TransFlection mode, the TRNFL option does not appear.
Procedure Options

desired value (from 100 to 3200).
Use these two options to set the minimum and maximum time interval between transmissions. Increasing the
repetition period reduces the amount of background noise in the signal at the expense of reducing the maximum
measurable flow rate. Since the DF868 adjusts repetition periods to optimize the flow measurement (taking flow rate,
transducer frequency, and signal characteristics into consideration), you must enter a range, from 100 to 3,200 µsecs.
Rep Period 1 specifies the shortest repetition period possible, with a default of 200 µsec. Rep Period 2 specifies the
longest repetition period the DF868 can use, and defaults to a value of 800 µsec.

Note:
8.
Once the DF868 determines the appropriate repetition period within the limits of Rep Period 1 and Rep Period
2, it alternates between transmits at the determined repetition period and a period that is 20% longer. For
example, if the DF868 selects a repetition period of 200 µsecs, it first transmits a series of bursts at 200
µsecs, followed by a series at 240 µsecs. The DF868 then compares the receive signals of the first series of
bursts to those of the second series. If the two series of signals are too dissimilar, the DF868 displays an
incoherent signal error.
Press [ENT] to accept the current XMIT per Reading value, or use the numeric keys to enter the desired value
(from 1,024 to 30,000) and press [ENT].
This option specifies the number of transmissions used to obtain a flow rate measurement. While reducing this
number improves the flowmeter’s response time, it also reduces its sensitivity in poor signal conditions. The default
value is 5,000.
Note:
To calculate the response time, divide the XMITs Per Reading value by the number of transmissions per
second. To determine the number of transmissions per second, divide 1 sec by the repetition period. For
example, if the XMITs Per Reading value is 10,000 and the repetition value is 200 µsec, the number of
transmissions per second is 5,000 (1/200), and the response time is 2 sec (10,000/5,000). Other examples
appear in Table 17.

1.10.4.4 The CODEL Option
Use this option to select the size of the transducer transmission signal. The option is helpful when measuring flow on
small pipes. Three selections are available:
•
AUTO - The meter determines code length (short or long) automatically, based on pipe size and transducer type.
•
1-bit - special use only (consult the factory before using)
•
2-bit - special use only (consult the factory before using)
•
4-bit - The 4-bit option consists of only a few pulses with no built-in code pattern. This option aids in cases where
a small pipe diameter does not give each transducer the time necessary to send a series of signals before
receiving a series of signals. It is also a good selection for pipes made of materials which tend to blur the signal
pattern, such as Teflon®.
•
11-bit - The 11-bit option consists of a series of approximately one dozen pulses with a distinctive binary pattern
that the meter can easily recognize during auto correlation.

MODBUS Register Map
When equipped with the optional MODBUS output card, the DF868 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 DF868 using the MODBUS, the control system must access the appropriate
register number, as shown in Table 20. Only registers 1-108 are available with the DF868 for MODBUS communications.
Registers 508-512 are used by the DF868 to store the MODBUS parameters.
Note:
If you request Ch2 or AVE data from a 1-Channel meter, the values will all be zero.

Temperature values must be entered in ascending order.
IMPORTANT: At the next prompt, the kinematic viscosity values entered must be in the range of 0.045 to 10000*10-6
ft^2/s or m^2/s. The values will appear as ft^2/s if the meter is set for English units or m^2/s if the meter
is set for metric units.
7.
Press [ENT] to accept the current Kin Viscosity value or enter a new value (with up to three decimal places) and
press [ENT].
The Temperature and Kin Viscosity prompts repeat until the number of pairs specified have all been entered. After
entering all the pairs, the meter returns to the User Program menu. If desired, repeat the above sequence to enter
additional tables for the other fluids (up to 3). To activate a table, refer to Calculating Kinematic Viscosity on page 34.
Activating this feature causes three changes to the standard software:
•
Whenever the temperature compensation option is active, the diagnostic parameter Fluid Temperature appears
for display and data logging.
Note:
If you are logging using PanaView, the Fluid Temperature diagnostic parameter is available even if the
temperature compensation option is deactivated. However, the units will be displayed as NOT ACTIVE.
•
If the current fluid temperature is outside the range of the tabulated values, then the last value that was within
the tabulated range will be used instead.
•
If the fluid temperature is in error due to an invalid analog input condition, the DF868 will continue to use the last
valid reading.
IMPORTANT: The tables entered for this feature are global, meaning that the same tables will be used for all sites in
the meter. Thus, editing the tables in any one site file will alter the values for all other site files. Also, the
tables are included as part of the site upload/download functions. For example, if you print out a site file,
the current contents of the tables will also be printed.

At any given time, the 120 records stored in one page of the log file will be graphed on the display screen. The cursor,
which is shown as a vertical line that extends the full height of the graph window, can be used to highlight any one of
these records.
IMPORTANT: Only the first of the three logged parameters is displayed in the graphical format of the LOG submenu.
Therefore, when creating a log file, be sure to specify the parameter to be graphed at the 1st Value

Introduction
This chapter explains how to use the Model DF868’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 DF868 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 cannot 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, 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.

are: 5sec, 10sec, 30sec, 1min, 3min, 6min, 12min, 30min and 60 min.
The time increment is the frequency at which the Model DF868 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:

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 DF868 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 [LOG].
a.
If you have activated the security feature (see Chapter 1, Programming Site Data, page 47 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 1, the number of
records = (24 x 60)/3 = 480 records. Then, from Equation 2, 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 two pages.

Introduction
The Model DF868 flowmeter has the capability to print any of the data stored in its memory using 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
information, refer to Chapter 6, Serial Communications and the brochure EIA-RS Serial Communications
(916-054).
After connecting the Model DF868 to a printer, the Print Menu is used to print live or logged data in either numeric or
graphical format. In addition, any site files stored in memory may be printed. The Print Menu is divided into the
following submenus:
•
•
•
•
•
PRNTR - use to specify the printer currently connected
DATA - use to print live data in numeric or graphical format
LOG - use to print a log file in numeric or graphical format
PROG - use to print a site file
STOP - use to terminate any active print jobs
For purposes of this discussion it is assumed that the left pane of the data display screen is active. If the right pane of
the data display screen is active, all of the instructions remain the same, except that any references to the [F1]-[F4]
keys should be replaced by the [F5]-[F8] keys.
Refer to the flow diagram in Figure 16, and proceed to the desired section for detailed instructions. Any submenu may
be followed in the sequence shown or the [ and [ keys may be used to scroll through the prompts.
Note:
If a printer has not yet been set up, the instructions in the PRNTR submenu on page 2 must be completed
before proceeding to any of the other submenus.

The Optional RS485 Serial Interface
Although the standard RS232 serial interface included with the Model DF868 is adequate for most applications,
Panametrics offers an optional RS485 serial interface upgrade for special situations. The Model DF868 is easily
modified to provide RS485 communications, and this section describes the wiring and use of the special RS232 to
RS485 converter.
Note:
For compliance with the European Union’s Low Voltage Directive (73/23/EEC), 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 DF868, just below the RS232 terminal block (see Figure 8). 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 (73/23/EEC), 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
DF868 may be wired directly to a single personal computer. To connect the RS485 serial interface, refer to Figure 8 on
page 3 and 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.
3.
Remove the clear plastic shroud that covers the electrical connectors.
Using a twisted-wire pair, connect the XMT+ terminal of the barrier strip to the T+/R+ terminal of the PC’s RS485
adapter and connect the XMT– terminal of the barrier strip to the T-/R- terminal of the PC’s RS485 adapter (see
the documentation provided with the RS485 adapter for details).
Note:
4.
The XMT+ terminal on the barrier strip is the screw opposite the red wire connection and the XMT– terminal
on the barrier strip is the screw opposite the green wire connection.
Reinstall the clear plastic shroud, close the cover to the electronics console and reconnect the main power.
The RS485 serial interface is now ready for point-to-point operation.
IMPORTANT: The installed version of the Model DF868 software must be Version F2Z or higher to support RS485
operation. If necessary, contact the factory for information about a software upgrade.
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.

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 DF868 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 DF868. 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.2
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).
C.3

E.16 Terminology
Configuration GUI and OPC Runtime modules use a specific terminology.
E.16.1 Communication Channel
A communication channel is a type of link on which an instrument is connected to a PC. Serial communication
channels such as RS232, RS485 (half/full duplex), and IR232 are supported for IDM based devices such as the
Panametrics XMT868i flowmeter and MIS1 hygrometer. Portable instruments, such as the Panametrics PT878GC gas
flowmeter and PM880 hygrometer, use the Infrared IRDA communication channel. Ethernet enabled devices, such as
the RF ValProbe and other Panametrics instruments, use the TCPIP channel.
E.16.2 Device
A device in the OPC configuration module is mapped to the corresponding physical instrument that performs actual
measurement. This device is added under a communication channel. Multiple devices can exist on one
communication channel, but the same device cannot exist under two or more communication channels.
E.16.3 Device Channel
A device has logical groups of entities to be measured. Device channels are embedded in firmware inside each
instrument. For Panametrics PanaLink instruments, device channels are mapped to Unit Types. Devices’ channels are
grouped under device; they are not editable and are specific to each device.
E.16.4 Attribute
An attribute is the entity measured by the device. Attributes are grouped under device channels, and cannot be
edited.
The hierarchy (parent-child relationship) of all of the above entities is summarized in Figure 47.

Creating a Communication Channel (cont.)
Once you have clicked on this option, a dialog form opens for you to enter details of various communication channel
properties. Refer to Figure 49.
Various fields in GUI will be appropriately enabled or disabled when you select a particular communication channel
type. For TCP/IP, the view does not allow you to select parameters, but provides the IP address and IP Port, as shown in
Figure 49. Be sure to follow the Naming Conventions for communication channels.
