Chapter 1. Installation

Chapter 1. Installation

1.1 Introduction

To ensure safe and reliable operation of the Model XGS868i Ultrasonic Flow Transmitter, the system must be installed
in accordance with the guidelines established by GE engineers. Those guidelines, which are explained in detail in this
chapter, include the following topics:

• “Unpacking” on page 1

• “Site Considerations” on page 2

• “Installing a Flowcell” on page 4

• “Installing Temperature and Pressure Transmitters” on page 4

• “Mounting the XGS868i Electronics Enclosure” on page 5

• “Making the Electrical Connections” on page 5

WARNING! The Model XGS868i flow transmitter can measure the flow rate of many gases, some of
which are potentially hazardous. In such cases, the importance of proper safety practices cannot be
overemphasized.

WARNING! Be sure to follow all applicable local safety codes and regulations for installing electrical
equipment and working with hazardous gases or flow conditions. Consult company safety personnel
or local safety authorities to verify the safety of any procedure or practice.

Attention European Customers! To meet CE Mark requirements, all cables must be installed as
described in Appendix A, CE Mark Compliance.

1.2 Unpacking

Carefully remove the electronics enclosure, the transducers, and the cables from the shipping containers. Before
discarding any of the packing materials, account for all components and documentation listed on the packing slip. The
discarding of an important item along with the packing materials is all too common. If anything is missing or damaged,
contact the factory immediately for assistance.

Chapter 1. Installation

1.3 Site Considerations

Because the relative location of the flowcell and the electronics enclosure is important, use the guidelines in this
section to plan the XGS868i installation. Figure 1 below shows a typical XGS868i flowcell ready for insertion into a
process line.

Figure 1: A Typical Model XGS868i System

1.3.1 Electronics Enclosure Location

The standard Model XGS868i electronics enclosure is a powder-coated, cast-aluminum, Type-7/4X explosion-proof
enclosure. An optional stainless-steel enclosure is available. Typically, the enclosure is mounted as close as possible to
the transducers. When choosing a site, make sure the location permits easy access to the electronics enclosure for
programming, maintenance and service.

Attention European Customers! 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 unit.

2 DigitalFlow™ XGS868i Startup Guide

Chapter 1. Installation

1.3.2 Flowcell Location

The pipeline flowcell consists of the flow rate transducers and any pressure and/or temperature transducers employed
as part of the flow measurement system. Ideally, choose a section of pipe with unlimited access to the flowcell. For
example, a long stretch of pipe that is above ground. However, if the flowcell is to be mounted on an underground pipe,
dig a pit around the pipe to facilitate installation of the transducers.

1.3.3 Transducer Location

For a given fluid and pipe, the Model XGS868i’s accuracy depends primarily on the location and alignment of the
transducers. In addition to accessibility, when planning for transducer location, adhere to the following guidelines:

1. Locate the transducers so that there are at least 20 pipe diameters of straight, undisturbed flow upstream and
10 pipe diameters of straight, undisturbed flow downstream from the measurement point. To ensure
undisturbed flow, avoid sources of turbulence in the fluid such as: valves, flanges, expansions and elbows, and
dips or low spots in which condensed liquid may collect.

2. Because condensate or sediment at the bottom of the pipe may cause attenuation of the ultrasonic signal, locate
the transducers on the side of a horizontal pipe, when possible. If limited pipe access necessitates top-mounted
transducers and the sound beam path includes a reflection, shift the transducers to at least 10° off top dead
center. This will minimize the influence of any sediment on the reflected ultrasonic signals.

1.3.4 Cable Lengths

Locate the electronics enclosure as close as possible to the flowcell/transducers, preferably directly on the flowcell.
However, the factory can supply transducer cables up to 1,000 ft (300 m) in length for remote location of the
electronics enclosure. If longer cables are required, consult the factory for assistance.

1.3.5 Temperature and Pressure Transmitters

When installing temperature and/or pressure transmitters in the flowcell, locate them downstream of the transducers.
These transmitters should be positioned no closer to the Model XGS868i transducers than 2 pipe diameters and no
further away from the transducers than 20 pipe diameters.

1.3.6 Transducer Cables

When installing the transducer cables, always observe established standard practices for the installation of electrical
cables. Specifically, do not route transducer cables alongside high-amperage AC power lines or any other cables that
could cause electrical interference. Also, protect the transducer cables and connections from the weather and corrosive
atmospheres.

Note: When using non-GE cables to connect the flow transducers to the Model XGS868i electronics enclosure, the

cables must have electrical characteristics identical to the GE cables. Type RG-62 a/u coaxial cable should be
used, and each cable must be the same length to within ±4 in. (10 cm).

1.4 Installing a Flowcell

A flowcell is the section of pipe where the transducers are mounted. It can be created either by mounting the
transducers on the existing pipeline or by mounting them on a spoolpiece. A spoolpiece is a separately manufactured
pipe section, matched to the existing pipe, which contains ports for mounting the transducers. This approach allows the
transducers to be aligned and calibrated before inserting the spoolpiece into the pipeline.

Figure 1 on page 2 shows a typical Model XGS868i spoolpiece, with a mounting bracket to hold the electronics
enclosure. For detailed instructions on installing the transducers and/or spoolpiece, refer to the supplied drawings and
the appropriate GE Transducer Installation Guide.

1.5 Installing Temperature and Pressure Transmitters

Optional temperature and pressure transmitters may be installed near the ultrasonic transducer ports as part of the
flowcell. Be sure to observe the siting requirements given earlier in this chapter. These transmitters should send a
0/4-20 mA signal to the Model XGS868i. In turn, the Model XGS868i must be fitted with a suitable option card to
process the signals and to provide the required 24 VDC power to the transmitters. Any desired transmitters or sensors
may be used, but they must have an accuracy equal to 0.5% of the flow rate reading or better.

Note: Resistive Thermal Devices (RTDs) are a good choice for measuring the temperature.

Typically, a 1/2” or 3/4” NPT female threaded port is used to mount the transmitters on the flowcell. If the pipeline is
insulated, the coupling may need to be extended to provide convenient access. Of course, other types of mounting
ports, including flanged ports, may be used for the transmitters.

Figure 2 below shows a typical mounting arrangement for the pressure and temperature transmitters. The temperature
sensor should protrude 1/4 to 1/2 way into the pipe.

Figure 2: Typical Temperature/Pressure Transmitter Mounting

1.6 Mounting the XGS868i Electronics Enclosure

The standard Model XGS868i electronics package is housed in a Type-4X weather-resistant enclosure suitable for
indoor or outdoor use. Refer to Figure 8 on page 21 for the mounting dimensions and the weight of this enclosure.

The Model XGS868i electronics enclosure is fitted with a mounting boss that has a single 3/4” NPTF threaded hole at
its center and four 1/4-20 tapped holes at its corners. By using this mounting boss, the electronics enclosure may be
mounted by any of the typical methods shown in Figure 9 on page 22.

WARNING! Proper grounding of the XGS868i chassis is required to prevent the possibility of electric
shock. See Figure 9 on page 22 for the location of the chassis grounding screw.

WARNING! Always disconnect the line power from the Model XGS868i before removing either the
front cover or the rear cover. This is especially important in a hazardous environment.

1.7 Making the Electrical Connections

This section contains instructions for making all the necessary electrical connections to the Model XGS868i flow
transmitter. Refer to Figure 10 on page 23 for a complete wiring diagram.

Except for the power connector, all electrical connectors are stored on their terminal blocks during shipment and may
be removed from the enclosure for more convenient wiring. Simply, feed the cables through the conduit holes on the
side of the enclosure, attach the wires to the appropriate connectors and plug the connectors back onto their terminal
blocks.

Attention European Customers! To meet CE Mark requirements, all cables must be installed as
described in Appendix A, CE Mark Compliance.

Refer to Figure 10 on page 23 to locate terminal block TB5 and connect the line power as follows:

WARNING! Improper connection of the line power leads or connecting the meter to the incorrect

line voltage may damage the unit. It may also result in hazardous voltages at the flowcell and
associated piping as well as within the electronics enclosure.

Attention European Customers! To meet CE Mark requirements, all cables must be installed as
described in Appendix A, CE Mark Compliance.

1. Prepare the line power leads by trimming the line and neutral AC power leads (or the positive and negative DC
power leads) to a length 0.5 in. (1 cm) shorter than the ground lead. This ensures that the ground lead is the last
to detach if the power cable is forcibly disconnected from the meter.

2. Install a suitable cable clamp in the conduit hole indicated in Figure 10 on page 23. If possible, avoid using the
other conduit holes for this purpose to minimize any interference in the circuitry from the AC power line.

3. Strip 1/4 in. of insulation from the end of each of the three power line leads.

4. Route the cable through the conduit hole and connect the line power leads to terminal block TB5, using the pin

number assignments shown in Figure 10 on page 23.

5. Leaving a bit of slack, secure the power line with the cable clamp.

1.7.5c Wiring a 0/4-20 mA Analog Inputs Option Card

To calculate the standard flow rates, the Model XGS868i requires accurate temperature and pressure data from the
measurement site. Transmitters installed in the flowcell can provide this information via an optional 0/4-20 mA analog
inputs option card. This option card includes two or four isolated 0/4-20 mA analog inputs (designated as A, B, C and
D), each of which includes a 24 VDC power supply for loop-powered transmitters. Either input may be used to process
the temperature signal, while the other input is used to process the pressure signal.

Note: To properly enter programming data into the meter, it is necessary to know which input is assigned to which

process parameter. This information should be entered in Appendix B, Data Records.

The analog inputs, which have an impedance of 118 ohms, should be connected with standard twisted-pair wiring.
Power to the transmitters may be supplied either by the integral 24 VDC power supply on the analog input option card
or by an external power supply. Figure 5 below shows typical wiring diagrams, with and without an external power
supply, for one of the analog inputs.

1.7.5h Wiring the MODBUS Option Card

The MODBUS option card uses the RS485 standard for MODBUS communication. The MODBUS card must be
installed in Slot 2. The RS485 standard allows up to 32 nodes (drivers and receivers) on one multi-drop network, at
distances up to 4000 ft (1200 m). GE recommends using 24-gauge (24 AWG) twisted-pair wire with a characteristic
impedance of 120 ohms and 120-ohm termination at each end of the communications line.

Note: The MODBUS option card provides its own RS485 connections. Thus, the meter can have its serial port

configured as RS232 and still provide RS485 MODBUS signals.

IMPORTANT: Because the MODBUS option card uses pins 1 and 2 on terminal block J2, only those option cards that

do not use these pins may be installed in Slot 1 when a MODBUS card is installed in Slot 2. Specifically,
only the option cards designated as OI and OR in Figure 11 on page 24 are compatible with the
MODBUS option card.

To link the XGS868i to the control system, refer to Figure 7 below and proceed as follows:

1. Connect the MODBUS – wire to Pin 2, the inverting or negative connection.

2. Connect the MODBUS+ wire to Pin 1, the non-inverting or positive connection.

3. Pin 3 has no connection.

1.7.5i Wiring the MODBUS/TCP Interface

Customers can also use a modified XGS868i that provides a MODBUS/TCP interface to communicate to an internal
network. An optional MODBUS/TCP card with a unique MAC (IP) address (installed only in slot 2) includes an RJ45
connector. To connect the MODBUS/TCP-enabled XGS868i to the network, insert the jack of an RJ45 cable into the
RJ45 connector, route the cable through one of the conduit holes using an appropriate cable clamp, and wire the other
end of the cable to the Ethernet network according to the manufacturer’s instructions. See Figure 13 on page 26.

Note: The MAC address for a specific XGS868i is included with the customer documentation. For more information

on setting up the MAC address, refer to Appendix C of the Programming Manual.

1.7.5j Wiring the Ethernet Interface

A modified XGS868i can use the Ethernet interface to communicate with a local area network. An optional Ethernet
card with a unique MAC (IP) address (installed only in slot 2) includes an RJ45 connector. To connect the
Ethernet-enabled XGS868i to the network, insert the jack of an RJ45 cable into the RJ45 connector, route the cable
through one of the conduit holes using an appropriate cable clamp, and wire the other end of the cable to the Ethernet
network according to the manufacturer’s instructions. An external connection is required between the Ethernet option
card and the XGS868i’s RS232 connector, as shown in Tab le 5 below and Figure 13 on page 26.

Note: The MAC address for a specific XGS868i is included with the customer documentation. For more information

on setting up the MAC address, refer to Appendix C of the Programming Manual.

1.7.5k Wiring the Foundation Fieldbus Interface

To connect the Foundation Fieldbus interface to the XGS868i, make the network connections at J8, pins 1 and 2, as
shown in drawing Y of Figure 13 on page 26. As an option, you can connect a shield to J8 pin 3, depending on the
network wiring.

No connections are made to J9 in normal operation. However, if you need to reset the network board to the factory
defaults, proceed as follows:

1. Connect a jumper between J9 pin 2 and J9 pin 3.

2. Power cycle (i.e., turn the power Off and then back On) the XGS868i.

3. Ten seconds after the power has been restored to the XGS868i, remove the jumper to return the network board

to normal operation.

1.7.5l Data Logging Option Card

The Model XGS868i can be fitted with a data logging option card, which must be installed in Slot 2. The data logging
option card increases the XGS868i memory by up to 2 MB.

Note: The data logging menu option is not available unless this option card is installed.

1.7.5m Procedure Options

After the Model XGS868i has been completely installed and wired, proceed to Chapter 2, Initial Setup, to program the
meter for taking flow rate measurements.

WARNING! Make sure both covers, with their o-ring seals, are installed and the set screws tightened
before applying power in a hazardous environment.

Chapter 2. Initial Setup

2.1 Introduction

This chapter provides instructions for programming the minimum amount of data required to place the Model XGS868i
flow meter into operation. Before the Model XGS868i can begin taking measurements and displaying valid data, the
system and pipe parameters must be entered. In addition, a 2-Channel meter requires that each channel be activated
prior to use. Additional programming options provide access to the more advanced features of the Model XGS868i, but
this information is not required to begin taking measurements.

Note: Refer to the Programming Manual for information on programming all other features. Be sure to record all

programming data in Appendix B, Data Records.

As a guide in following the programming instructions in this chapter, the relevant portions of the Model XGS868i
menu map have been reproduced in Figure 15 on page 39.

2.2 Programming Methods

Note: See the Programming Manual for information on those User Program features not covered in this chapter.

You can program the XGS868i via either the magnetic keypad on the lower part of the glass enclosure, or GE’s
PanaView™ software, which is a PC-based, non-resident software program that communicates with the XGS868i via
its RS232 serial port. PanaView supplements basic XGS868i functions with several additional capabilities, such as:

• 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 GE instruments.

This chapter focuses on programming via the magnetic keypad. For more information on programming the XGS868i
via PanaView, refer to Appendix C of the Programming Manual.

2.3 The XGS868i Enclosure Keypad

Along with the 2-line, 16-character LCD, the XGS868i includes a 6-key magnetic keypad. The decal cutout for each
key contains a hall effect sensor, pushbutton switch and visible red LED. The magnetic wand used to activate a
magnetic key is attached below the front panel of the electronics enclosure. An operator activates the key by pressing
the magnetic wand against the glass cover over the desired key. The LED will light indicating a successful key press.

WARNING! The pushbutton switch can also act as a key press but it must be done with the front
cover of the electronics enclosure removed. Do not use the pushbutton switch in a hazardous area
where the cover must not be removed.

Use the magnetic keypad to navigate through the user program. The menu map may be followed in sequence, or the
four arrow keys may be used to scroll through the prompt screens. Figure 14 below shows the front of the XGS868i,
with magnetic keypad and magnetic wand.

Figure 14: XGS868i Magnetic Keypad and Wand

IMPORTANT: The magnetic keypad permits programming of the meter through the glass faceplate without removing

the cover. Thus, all programming may be performed while the meter is installed in a hazardous area.

These six keys on the keypad enable users to program the XGS868i:

• [Enter] - confirms the choice of a specific option and a data entry within that option

• [Escape] - allows users to exit from a specific option without entering unconfirmed data

• [] and [] - enable users to view a specific measurement in the Key display setting (see page 45) or to scroll

through a list of options in a menu. Also, used to change a selected character in a string.

• [] and [] - enable users to scroll to a specific option, among available choices in a menu, or to select a

specific character in a text entry.

Chapter 3. Operation

3.1 Introduction

See Chapter 1, Installation, and Chapter 2, Initial Setup, to prepare the Model XGS868i system for operation. When
the meter is ready to take measurements, proceed with this chapter. The following specific topics are discussed:

• “Powering Up” on page 42

• “The Optional PanaView Display” on page 44

• “Taking Measurements” on page 45

Note: All inputs and outputs of the Model XGS868i are calibrated at the factory, prior to shipment. If it becomes

necessary to recalibrate any of the inputs and/or outputs, see Chapter 1, Calibration, of the Service Manual for
instructions.

WARNING! To ensure the safe operation of the Model XGS868i, it must be installed and operated as
described in this manual. Be sure to follow all applicable local safety codes and regulations for
installing electrical equipment and working with hazardous gases or flow conditions. Consult
company safety personnel or local safety authorities to verify the safety of any procedure or
practice.

DigitalFlow™ XGS868i Startup Guide 41

Chapter 3. Operation

3.2 Powering Up

Because the Model XGS868i does not have an ON/OFF switch, it will power up as soon as the connected power source
is energized.

Attention European Customers! 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 unit.

There are three methods for obtaining readings from the XGS868i:

• Built-in LCD display

• PanaView software on a computer

• Device to read the XGS868i analog output

At least one of the above display options must be installed in order to obtain flow rate readings from the meter.

Immediately upon power up the software version display appears. Then, the meter performs a series of internal checks,
which take about 45 seconds, prior to displaying the flow rate data.

Note: If the Model XGS868i fails any of the internal checks (see Chapter 2, Error Codes, in the Service Manual), try

disconnecting the power and then powering the unit back On. If the meter continues to fail any of the internal
checks, contact the factory for assistance.

After successfully performing the internal checks, the Model XGS868i begins taking measurements and the software
version display is replaced by a measurement mode display. Proceed to the appropriate section for instructions on using
the LCD display and the PanaView display option.

Note: As a minimum, the system and pipe parameters (for each installed channel of a 2-channel meter) must be

entered before the Model XGS868i can display valid data. Refer to Chapter 2, Initial Setup, for specific
instructions.

Appendix C. Measuring P and L Dimensions

C.1 Introduction

When programming the PIPE menu in the Model XGS868’s User Program, the path length (P) and the axial dimension
(L) must be entered. These parameters are determined by measurements on the actual transducer installation, with P
equal to the face-to-face distance between the transducers and L equal to the axial distance between the centers of the
transducer faces.

The accuracy of the programmed P and L values is critical to precise flow rate measurements. If GE supplies the
flowcell for the system, the correct values will be included in the documentation supplied with the system. For
transducers installed on an existing pipe (see Figure 22 on page 68), P and L must be measured at the site. This
appendix provides instructions for properly determining these dimensions.

C.2 Measuring P and L

Whenever possible, physically measure the face-to-face distance (P) and the axial distance (L) between the centers of
the flat faces of the transducers. Refer to Figure 22 on page 68 for an illustration of the proper distances to measure, in
a typical installation.

In some situations only one of the required distances can be directly measured. When this happens, a knowledge of the
installation angle (θ) of the transducers, permits the second distance to be calculated from Equation C-1 below:

(C-1)

As an example, assume that the transducer installation angle is known to be 45° and the L distance is measured to be

10.00 inches. Then, the P distance is calculated to be P = 10.00/0.707 = 14.14 inches.

With a Bias 90° transducer installation, it sometimes happens that the only known parameters are the transducer angle

(θ) and the centerline distance between the transducer bodies (CL). In these cases, it is still possible to calculate P and
L by combining Equation C-1 above with the additional Equation C-2 below (see Figure 22 on page 68):

(C-2)

Standard GE 90° transducers have the face offset from the centerline of the body by 0.6 inches. Thus, a pair of

transducers has a total offset of 1.2 inches, as indicated in Equation C-2 above. For example, suppose that the
transducer installation angle is 30° and CL is measured to be 12.00 inches. Then,
P = 12.00 – 1.2 = 10.80 inches and L = 10.80 x 0.866 = 9.35 inches.
