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.

2.0 Introduction
To ensure safe and reliable operation of the PanaFlow LZ
flow meter system, it must be installed in accordance with
established guidelines. Those guidelines are discussed in this
manual and in the flow transmitter Manual.
IMPORTANT:
The PanaFlow LZ flow meter system may be supplied
with a variety of Panametrics flow transmitters (XMT1000,
XMT910, XMT900, XMT868i, etc.). Be sure to refer to the User’s
Manual for your specific flow transmitter.
Attention!
Because the PanaFlow LZ system has the
flexibility to use several different Panametrics
flow transmitters, the photographs used in
this manual may appear slightly different
from your system. However, the basic
instructions are valid for all PanaFlow LZ
systems.
WARNING!
The PanaFlow LZ flow meter can measure
the flow rate of many fluids, some potentially
hazardous. 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
fluids or flow conditions. Consult company
safety personnel or local safety authorities to
verify the safety of any procedure or practice.
Attention!
To meet CE Mark requirements, all cables
must be installed as described in the
flow transmitter User’s Manual. CE Mark
compliance is required for all systems
intended for use in EU countries.

3.0 Unpacking the PanaFlow LZ System
Before removing the PanaFlow LZ system from the crate,
please inspect the flow meter. 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.
3.1 Identification
The PanaFlow LZ meter has up to three separate labels for
identification, depending on its configuration. The system
is mounted as a single unit.The six keys on the magnetic
keypad are used to program the XMT1000:
3.2 Lifting the PanaFlow LZ System
Figure 1 below indicates the proper way to attach the lifting
straps to any Panametrics flow meter system.
Attention!
Because the PanaFlow LZ system has the
flexibility to use several different Panametrics
flow transmitters, the photographs used in
this manual may appear slightly different
from your system. However, the basic
instructions are valid for all PanaFlow LZ
systems.
WARNING!
This is the only approved way to lift a
PanaFlow system into position in the pipeline.
Never lift the system by the flow transmitter
mounted on top of the flowcell.

4.0 Site considerations
4.1 Local mounting
The flow transmitter 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 2 below). Undisturbed flow means
avoiding sources of turbulence in the fluid (e.g., valves, flanges, expansions, elbows, etc.), avoiding swirl, and avoiding
cavitation.
Flow Direction
10D 5D
Figure 2: Minimum straight run pipe requirements
• 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 3 below).

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.

4.2 Remote mounting
The standard flow transmitter 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!
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 transmitter.
4.3 Cable lengths
Locate the flow transmitter as close as possible to the
transducers. The maximum distance from the transducers
for remote mounting is 1000 ft (300 m) using RG-62 coaxial
cable or equivalent. If longer distances are required, consult
the factory for assistance.
4.4 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.
4.5 Insulation
Do not place thermal insulation on or around the transducer
locations or the flow transmitter. The enclosures act as heat
sinks that protect against high and low temperatures.
4.6 Vibration exposure
considerations
Whenever possible, install the flow transmitter in a location
isolated from vibrations. Avoid installing it near equipment
that generates low-frequency, high-energy random
vibrations.
4.7 Sunlight exposure
The installer should consider and limit exposure of the flow
transmitter to direct sunlight. Sunshades should be utilized
in extreme environments.

5.0 Installing cable glands
When wiring the PanaFlow LZ system in accordance with the instructions in the flow transmitter User’s Manual, it is essential
that the cable glands be properly installed. To accomplish this, carefully complete the following steps:
WARNING!
Failure to properly install the cables in the glands will compromise the environmental ratings of the
PanaFlow LZ system.
Note: These instructions apply to all installations using the Panametrics 704-861, 704-862, and 704-863 cable assemblies.
1. Remove the Rubber Boot from the cable gland and slide it back over the cable (see Figure 4 below).
Figure 4: Removing the rubber boot
2. Disassemble the Cable Gland (see Figure 5 below). However, DO NOT try to separate the pieces of the Armor Clamp that
secures the cable armor, as these pieces are permanently assembled.

5.0 Installing cable glands (cont.)
13. After the coaxial cables have been properly installed in their cable glands, they must be connected to the terminal blocks
inside the flow transmitter enclosure (see Figure 16 below) as follows:
Attention!
Because the PanaFlow LZ system has the flexibility to use several different Panametrics flow transmitters,
the photographs used in this manual may appear slightly different from your system. However, the basic
instructions are valid for all PanaFlow LZ systems.
a. Connect the transducer wires to their terminal block per the instructions in the for your flow transmitter.
b. Make sure all of the transducer wires are properly dressed and that they are neatly arranged inside the flow
transmitter enclosure.
c. Use the flexible strain reliefs inside the flow transmitter enclosure to keep all of the transducer wires clear of the
threaded areas.
