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.
Visit www.bakerhughesds.com/health-safetyand-environment-hse for take-back instructions and more information
about this initiative.

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 shows a typical XGS868i enclosure and spoolpiece 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.
Note:
For compliance with the European Union’s Low Voltage Directive (2006/95/EC), 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 Model XGS868i.

DigitalFlow™ XGS868i Startup Guide 3
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-Panametrics cables to connect the flow rate transducers to the Model XGS868i electronics
enclosure, the cables must have electrical characteristics identical to the Panametrics cables. Type RG62
a/u coaxial cable should be used, and each cable must be the same length (within ±4 in.).

Chapter 1. Installation
4 DigitalFlow™ XGS868i Startup Guide
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 enclosed Panametrics
Gas Transducer Installation Guide (916-049).
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 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 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.
