2 Preparing for installation
Prerequisites
The Emerson Wireless Gateway should be installed and functioning
properly before commissioning the Rosemount ET410 and powering
it with a BP20E power module.
Note
Wireless devices should be powered up in order of proximity
from the Gateway, beginning with the closest device, then working
outward from the Gateway. This results in a simpler and faster
network formation. Enable Active Advertising on the Gateway to
ensure new devices are able to join the network faster. For more
information, see the Emerson Wireless 1410S Gateway.
Procedure
1. Identify the location where the sensor is to be installed.
2. Ensure that all cladding and insulation is removed around the
circumference of the pipe at the sensor location.
The dimension drawing in Figure 2-1 provides guidance on
how much pipe should be exposed.
Note
Cladding or insulation can be replaced after the sensor
installation is completed, provided that the head of the sensor
remains outside of the insulation. Insulation materials can be
installed around the sensor as desired and according to local
procedures.

Figure 2-1: Transmitter dimensions
Note
Dimensions are in millimeters [Inches].
3. Clean the area where the sensor will touch the pipe to
remove any particles that might keep the transducer away
from the pipe surface or damage the face of the transducer. A
permanent marker may be used to show exactly where each
sensor is to be placed on the pipe.

3 Mounting the transmitter with a strap
3.1 Mounting the transmitter
If you are using the strap mounting option, perform the tasks in this
section.
If you are using the magnetic fixture, skip this section and go to the
Mounting the transmitter with a magnetic fixture.
WARNING
Two people are required for this operation
Personal protective equipment (PPE) of gloves and safety glasses
or full-face visor are recommended.
Cut strap may have sharp edges.
Do not cut the strap while it is under tension because this action
can result in damage or injury.
Procedure
1. Unbox the strap tensioner and the strap from the packaging.
2. Feed the strap into one end of the strap tensioner and using
the screwdriver or wrench and socket provided, turn the screw
on the tensioner until the end of the strap emerges from
under the worm drive (at least 5 turns of the worm-screw are
required).
3. Remove the protective cap from the sensor.
CAUTION
Once the protective cap is removed, the strong magnetic field
at the end of the sensor can suddenly attract other objects,
such as tools. This can cause injury as well as damage to the
sensor.
Only remove the protective cap when necessary and then take
great care. Ensure tools and fastenings are kept away from the
sensor when the cap is removed.
4. Carefully place the sensor on the required location on the
pipe.
5. Check the sensor is on the location correctly and the
thermocouple is in contact with the surface.

NOTICE
The magnets used in the sensor have a high pull force. To
avoid damage, and to get the precise location for each
sensor, initially place the sensor at an angle to the pipe and
the gently lower the sensor onto the pipe.
There is also a thermocouple in the foot of the sensor.
When installing, ensure that the thermocouple is in contact
with the measurement surface.

Quick Start Guide 11

NOTICE
WARNING
One person should hold the sensor until the strap has been
installed.
6. Feed the strap through the slot hole of the sensor and around
the pipe.
7. If there is an excessive length of spare strap, the excess may
be cut off. Lay the strap over the tensioner worm-drive and
make the cut just after the screw head.
8. Feed the free end of the strap into the other end of the
strap tensioner. Using the screwdriver or wrench and socket

provided, turn the screw on the tensioner until the end of the
strap emerges from the worm-drive (at least 5 turns of the
work screw is required).
Important
Do not tension the strap yet.
9. Position the strap tensioner so that the strap (D) just touches
the pipe (B) between the sensor (A) and the strap tensioner (C).
Note
For examples of correct and incorrect installation, information
for pipes with different diameters and mounting multiple
sensors on a single strap, refer to Strap installation
considerations.
3.2 Strap installation considerations
Positioning on different sized pipes
The relative positions of the strap tensioner and sensor change
depending on the pipe diameter. On pipes with less than a 4-inch
diameter, position the sensor and tensioner on opposite sides of the
pipe. The following figure displays placement for different size pipes.
April2023 Quick Start Guide
Quick Start Guide 13

A. Large pipes
B. Pipes > 4 inches diameter
C. Pipes < 4 inches diameter
Note
If there are obstructions that do not allow for the recommended
strap tensioner position relative to the sensor, then move the strap
tensioner away from the sensor to the closest accessible position.
Incorrect transmitter installation
No contact area, the sensor and tensioner are too close together.
Contact area is too large, sensor and tensioner are too far apart.
Quick Start Guide April2023
14 Emerson.com/Rosemount

Mounting multiple sensors
When mounting multiple sensors on a single strap, only one
tensioner is required. It is important to ensure the strap makes
contact with the pipe between each of the sensors and the tensioner.
A. Correct positioning: Strap is in contact with the pipe between the
sensors and the tensioner.
B. Incorrect positioning: Strap is not in contact with the pipe between
the sensors and the tensioner.
Use the following table below to determine the maximum number of
sensors that can share the same strap and tensioner for a given pipe
size.

Note
This also limits the locations you can mount multiple sensors on a
pipe using a single strap. If closer spacings are desired, multiple
straps must be used.
3.3 Commissioning the sensor
Commissioning allows the sensor to securely join a designated
network and communicate with a gateway. The IK220 installation kit
comes with a commissioning interface (CC21) and a tablet PC with
the Permasense installation application installed. The CC21 provides
an electronic interface between the ET410 sensor and the tablet PC
during commissioning.
The installation application software is used to:
1. Provision the WiHART network configuration on the sensor.
2. Monitor the quality of the ultrasonic signal during mechanical
installation.
Both of these steps are required to complete the commissioning.
Note
All sensors connected to the network and Gateway must have the
same network ID and join key.
Procedure
1. Power up the rugged tablet PC and connect the CC21
commissioning interface to the tablet PC USB port.

2. Double-click the Permasense installation application desktop
icon.
Within approximately 10 seconds, the Permasense installation
tool software should open.
3. Attach the CC21 to the sensor.
4. In the installation application software:
a) Verify both the sensor ID and the sensor's MAC address,
which are displayed at the top of the screen within 10
seconds.
b) Select the Provision tab.
c) Enter the 5-digit network ID and the 32-hexadecimal
(numbers 0-9 and letters A -F) join key.
d) Click the Provision button.
The system provides confirmation once provisioning is
complete.
e) Ensure the network ID of the gateway is visible in the
Network Discovery panel.
Note
Joining the device to the network could take several minutes.

3.4 Sensor installation
Procedure
1. Click the Installation tab in the installation application
software.
2. Click the Start button and wait for an ultrasonic waveform to
download from the sensor.
April2023 Quick Start Guide
Quick Start Guide 17

Note
Waveforms are automatically downloaded every 10 seconds.
When a new waveform arrives, the lines briefly become
thicker.
3. Check the quality of the waveform.
Need help?
The first one or two reflections must be well defined above the
noise in the signal. Only one reflection is needed to calculate
the thickness. If the signal is poor, move the sensor to a
slightly different position. Noting that this should not be done
by sliding the device across the measurement surface.
Figure 3-3: Installation application software, installation
tab
a. Good waveform
b. Poor waveform
4. Ensure that the measured thickness matches expectations.
5. Ensure the strap tensioner, strap, and sensor(s) are in line
before tightening the work-screws on the strap tensioner.

Figure 3-4: Correct strap alignment
Tip
This step is critical to the strap tensioner functioning as
intended. Continuously check alignment while performing the
following step. As the tensioner is tightened, ensure the
sensor(s), strap and strap tensioner remain in-line.
6. Tighten both worm-screws with the flathead screwdriver or
the wrench and socket provided, ensuring the tensioner
does not slide relative to the pipe. As the worm-screws are
tightened, observe the position of the metal plate on top of
the spring through the plus-shaped (+) cut-out on the side
of the tensioner. The correct tension is set when the plate is
aligned with wide part of the middle of the cut-out as shown in
the images below.
WARNING
Take special care not to put fingers under the bolts of the
tensioner while the strap is being tensioned.
April2023 Quick Start Guide
Quick Start Guide 19

Figure 3-5: Alignment examples
A. Correct tension – Plate is aligned with the wide part of the
cut-out.
B. Incorrect alignment – Plate above the wide part of the cut
out, tighten strap.
C. Incorrect alignment – Plate below the wide part of the cut
out, loosen strap.
NOTICE
When the worm-screws are tightened, the springs in the
tensioner are compressed. To avoid the strap becoming lose
or over-tightened when the pipe temperature changes, it is
important that the spring is set to the correct tension. Do not
over-tighten the worm-screws.
7. Ensure the metal plate is centered through the plus (+) shaped
cut-outs on both sides of the tensioner. If it is not centered,
either loosen or tighten the worm-screws on either side until
they do align. Ensure the sensor is firmly fixed and sitting
perpendicular to the pipe as shown in Figure 3-4.
8. When all the adjustments have been completed, make a final
check of the waveform quality (refer to Figure 3-3).
