Signet 3350/3550 Ultrasonic Flowmeter
3-3350.090 Rev. A 11/05 English
3-3350.090
1. Description
The Signet 3350/3550 Ultrasonic Flowmeter uses transit-time technology to deliver
accurate flow rate and totalizer information with no direct fluid contact.
Originally used for temporary installations and periodic flow rate validation, today these
ruggedized instruments are perfectly suited to applications where pipes cannot be
penetrated, or where the fluid medium is hazardous or easily contaminated.
The clamp-on sensors are easy to install, without interrupting the process stream. Simply
enter the pipe parameters and the application preferences; the 3550 will provide stable and accurate data that is tailored
by you, for your unique requirements.
The Ultrasonic Flowmeter is programmable via the front panel keypad. Select display menu instructions in English,
French, Spanish, German or Japanese on a 2-line, backlit LCD.

Installation and Quick Start Guide
The electronics may be mounted on a wall or on a pipe
stand.
• For wall mounting, use two M8 bolts. Drill holes based
on the dimensions illustrated here.
• For pipe mounting, use the two U-bolts supplied with
the unit.

Mounting
plate
1. Select a mounting location and method for the 3350 electronics.
The installation and startup of this flowmeter is divided into
seven steps. They are organized in the sequence they
should be completed:
1. Select a mounting location and method for the 3350
electronics.
2. Select a location and mount the 3550 strap-on sensor
assembly onto the pipe.
3. Connect the sensor cables and 24 VDC power to the
electronics terminals.
4. Navigate to the MEASURE SETUP menu and enter
the information for your pipe and fluid.
5. Position the two ultrasonic transducers at the spacing
indicated by the PIPE PARAMETER and secure them
in the frame.
6. Review the system troubleshooting information and the
initial values of the output parameters in this manual to
determine if it is safe to start the flowmater.
7. Program the 3350 flowmeter electronics to reflect the
remaining application requirements.

The length of upstream and downstream straight pipe of
the ultrasonic detector should be long enough to ensure
accurate measurements.
2A. Select a location for the 3550 strap-on sensor assembly.
The sensor can be installed at any
position around the pipe when
attention is given to the following
requirements:
• The pipe must be completely
filled with fluid.
• IOn horizontal pipes, mount
the sensors at ±45° from the
horizontal plane to avoid air
pockets and debris that may
accumulate at the top and
bottom of the pipe.
• The pipe surface must be free
of pits and distortions. Use
thinner, sandpaper, etc., to
remove and surface corrosive,
rust, etc, and to remove any
rust, pitch, or other materials
from the pipe surface.
• Do not mount the sensors on a
section of pipe that is visibly out-
of-round, or straddling a flange
or weld seam.

3. Place the frame on a pipe smooth, clean section sub-
jected to a surface treatment.
4. Temporarily tighten the first stainless steel belt on the
pipe.
5. Adjust the frame so it is parallel with the pipe, put the
spring fixture to the side of the frame and tighten the
stainless steel belt so that the frame will tightly be fitted.
Mounting on pipe whose diameter is DN150 (6 in.) or
larger, connect 2 stainless steel belts.
6. After tightening both stainless steel belts, slide the
spring fixture to the opposite to the frame.
Note: Frame must be relocated, use new stainless steel
belts.
1. Slide the spring fixture onto the stainless steel belt. 2. Pass the stainless steel belt through 2 belt holes on the
frame.
Handle the steel mounting belts carefully to avoid injury.
2b. Mount the 3550 strap-on sensor assembly onto the pipe

Connect the signal line with BNC connectors to the sensor
units. Engage the red BNC connector upstream, and the
black BNC connector downstream.
Before mounting the sensor unit into the frame, Apply
silicone (or silicone-free grease) over the transmission
surface of the sensor unit. Do not leave any bubbles.
When using silicon-free grease, do not exceed the fluid
temperature range:
• Silicon rubber: 20 to 100°C
• Silicon-free grease: 0 to 60°C
Silicon-free grease should be reapplied approximately once
every 6 months. (Silicon rubber need not be reapplied.)
Insert the sensor unit into the frame. The UPSTREAM and
DOWNSTREAM sensors must be spaced according to the
PIPE PARAMETER results. Do not lock the sensors yet.
They will need to be adjusted in step 5.
Mount both sensor units so as to be roughly symmetrical
with respect to the frame.
