Chapter 1. Installation
1.1 Introduction
To ensure safe and reliable operation of the XMT1000, it must
be installed in accordance with the established guidelines.
Those guidelines, explained in detail in this chapter, include
the following topics:
• Unpacking the XMT1000
• Selecting the location for the XMT1000 (local or remote)
• Installing the XMT1000 at the selected location
• Wiring the XMT1000
WARNING!
The XMT1000 flow transmitter can measure
the flow rate of many fluids, some of which
are potentially hazardous. The importance
of proper safety practices cannot be
overemphasized.
Be sure to follow all applicable local safety codes and
regulations for installing electrical equipment and working
with hazardous fluids 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 marking requirements, all
cables must be installed as described in
“CE marking compliance.”
1.2 CE marking compliance
For CE marking compliance or installation in high noise
areas, the XMT1000 flow transmitter must be wired in
accordance with the instructions in this section.
IMPORTANT:
CE marking compliance is required for all units intended
for use in EU countries.
The XMT1000 must be wired with the recommended
cable, and all connections must be properly shielded
and grounded. Grounding of the chassis must be within
10 ft (3 m) of the transmitter. Refer to table 1 below for the
specific requirements.

1.3 Unpacking the XMT1000
Before removing the XMT1000 from its box, please
inspect both the box and the instrument carefully. Each
instrument manufactured by Panametrics is warranted
to be free from defects in material and workmanship.
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 Panametrics
Customer Care immediately for assistance.
The XMT1000 is supplied with both a serial number
label and a certification label for identification of the
instrument (see figure 1 below and figure 2). The system
can be mounted either on an existing meter body (local
mounting) or at another location via a connecting cable
(remote mounting).

1.4 Site and clearance considerations
1.4.1 Access to the meter
Because the relative location of the flowcell and the
XMT1000 transmitter is important, use the guidelines in
this section to plan the XMT1000 installation.
For flowcell clearance recommendations, consult the
manual for your specific flow meter system or contact
Panametrics for assistance. Access to the XMT1000 flow
transmitter should be uninhibited, as defined by the
minimum clearance distances around the enclosure
specified in figure 3.
1.4.2 Vibration exposure considerations
Whenever possible, install the XMT1000 flow transmitter
in a location isolated from vibrations. Avoid installing
it near equipment that generates low-frequency,
high-energy random vibrations.
1.4.3 Sunlight exposure
The installer should consider and limit exposure of the
XMT1000 flow transmitter to direct sunlight. Sunshades
should be utilized in extreme environments.

1.4.4 Local mounting
The XMT1000 accuracy is affected by the flowcell
location in the process piping and on the orientation
of the transducers. Thus, in addition to accessibility
for maintenance, adhere to the following installation
guidelines:
• Locate the flowcell so that there are at least 10 pipe
diameters of straight, undisturbed flow upstream
and 5 pipe diameters of straight, undisturbed flow
downstream from the measurement point (see
figure 4). Undisturbed flow means avoiding sources
of turbulence in the fluid (e.g., valves, flanges,
expansions, elbows, etc.), avoiding swirl, and
avoiding cavitation.
• Locate the transducers on a common axial plane
along the pipe. Also, locate them on the side of the
pipe instead of on the top or the bottom, because
the top of the pipe tends to accumulate gas and
the bottom tends to accumulate sediment. Either
condition will cause unwanted attenuation of the
ultrasonic signals. There is no similar restriction with
vertical pipes, as long as the fluid flow is upward to
prevent free falling of the fluid or a less than full pipe
(see figure 5).
CAUTION!
Do not place thermal insulation on or
around the transducers, the junction boxes,
or the meter electronics. The transducer
and junction box act as a heat sink that
protects the transducer from high and
low temperatures.
1.4.5 Remote mounting
The standard XMT1000 enclosure is a powder-coated,
aluminum, IP67 explosion-proof enclosure. Typically,
the enclosure is mounted as close as possible to
the transducers. When choosing a site for a remote-
mount installation, which is recommended for process
temperatures exceeding 150°C, make sure the location
permits easy access to the 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.
1.4.6 Cable lengths
Locate the XMT1000 as close as possible to the transducers.
The maximum distance from the transducers for remote
mounting of the XMT1000 is 1000 ft (300 m) using RG-62
coaxial cable or equivalent. If longer distances are required,
consult the factory for assistance.
1.4.7 Transducer cables
When installing the transducer cables, always observe
established standard practices for the installation of
electrical cables. 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, and be sure to follow the manufacturer’s
installation guidelines if cable glands are provided.

Chapter 2. Programming
2.1 Introduction
This chapter provides instructions for programming the
various features of the XMT1000 flow transmitter. Before the
XMT1000 can begin taking measurements, settings for the
user preferences and inputs/outputs must be entered and
tested. To program your XMT1000, see the next section for
programming instructions and refer to “menu maps” to
configure the desired features.
Note: For help with the programming of any system
parameters which may be unclear, refer to “glossary of
terms” for a brief description of the standard flow meter
terminology used in this manual.
2.2 Using the magnetic keypad
The display window on the XMT1000 includes the
components shown in figure 7 below.
Figure 9: The display and keypad
IMPORTANT:
The XMT1000 magnetic keypad enables programming
of the instrument through the glass faceplate without
removing the cover. Thus, all programming procedures
may be performed while the unit is installed in a
hazardous area.
Above the display, the blue light is for power indication and
the red light is for system health indication. Once system
power is applied, the blue light stays on until power is lost.
The red light blinks when the system is in error. When the
red light is off - the system is operating without error.
The six keys on the magnetic keypad are used to program
the XMT1000:
• [√] - confirms the choice of a specific option and data
entry within that option
• [] - enables users to exit from a specific option without
entering unconfirmed data
• [] and [] - enable users to highlight a specific window
in the display option or to scroll through a list of options
(parameters, letters, and numbers, 0-9 as well as the
negative sign and decimal point) in a menu
• [] and [] - enable users to scroll to a specific option,
among choices in an option, or to a character in a
text entry.
When the XMT1000 is powered up, the initial screen display
appears, followed by meter boot up, then by a display of
measurement parameters.
As a guide to help follow the programming instructions
in this chapter, the XMT1000 menu maps have been
reproduced in figure 8 on through figure 15.
IMPORTANT:
If the keypad has not been pressed for 10 minutes,
the XMT1000 exits the keypad program and returns to
displaying measurements. Because changes can only be
retained after the user confirms them, the meter discards
any unconfirmed configuration changes.
2.3 Passcodes
The default passcodes for the XMT1000 flow transmitter are:
• Default operator password = 111111
• Default admin password = 111111
IMPORTANT:
The default admin password must be changed before
the meter is placed into service, and the new admin
password must be properly secured. Unauthorized access
to the admin menus may result in programming changes
that have a negative impact on the performance and
operation of the meter.

2.4 Glossary of terms
• Backlight: The LCD display backlight has three
user-adjustable parameters. The brightness, the
contrast, and the length of inactivity which triggers
automatic shutdown can be individually set within
available limits.
• Error handling: The manner in which various
XMT1000 outputs respond to automatically generated
system errors can be set by the user by selecting the
options from a drop-down list.
• Frequency output: In frequency mode, the digital
output generates a pulse with a frequency that is
proportional to the magnitude of the measured
flow parameter (e.g., 10 Hz = 1ft3/hr).
• HART: HART is a serial communication protocol
used for industrial automation. Its main advantage
is that it can communicate over 4-20 mA analog
instrumentation current loops over the pair of wires
used by the analog only host system.
• K-factor: To calibrate the XMT1000 against a
reference value, the raw flow velocity readings
may need to have a correction factor applied.
This K-factor can be a single constant or a table of
K-factor vs. velocity values.
• Loop powered: Loop powered analog devices
use the power provided by the meter itself rather
than by an external power supply. This results
in a simple 2-wire connection between the meter
and the external device.
• Mass flow: mass flow is the mass of fluid passing
the measurement point in a given period of time.
This value is calculated by the meter from the
measured flow velocity and the programmed pipe
and fluid parameters.
• Modbus: Modbus is a serial communication
protocol developed by Modicon® for use with its
programmable logic controllers. It is a method
used for transmitting information over serial lines
between electronic devices.
• Pulse output: In pulse/totalizer mode, the digital
output generates a pulse with a width corresponding
to one unit of the measured flow parameter
(e.g., 1 pulse = 1 ft3).
• Reynolds correction: When turned on, a factor
based on the kinematic viscosity and the flow rate
of the fluid is applied to all measurements. Reynolds
correction should be On for most applications.
• Serial port settings: When the XMT1000 serial
port is connected to an external serial device,
communication between the two devices only
occur if the serial port settings of the two devices
match. These settings include: baud rate, data bits,
stop bits, and parity.
• Special transducer: If your transducer has no
number engraved on the body, select SPECIAL
in the transducer number menu.
• Tw: The TW parameter is the time the transducer
signal spends traveling through the transducer
body and the transducer cable. This value must
be subtracted from the total signal transit time
to calculate the actual signal transit time only
through the fluid.
• Totalizer: The totalizer accumulates a running
total of the amount of fluid which passes the
measurement point between specified start and
stop times.
• Tracking window: The tracking window is used
to detect the receive signal when you are unsure
of the fluid sound speed. For the XMT1000 flow
transmitter, the tracking Window is always ON.
• Zero cutoff: When the measured flow rate is
below the zero cutoff value, the display is forced
to 0.00. This is to avoid rapid fluctuations in the
reading whenever the flow rate is close to zero.
