The purpose of this document is to provide an overview of the CiDRA
SONARtrac system startup and operation. It is not intended to
replace reading the full manual.
This overview and the installation manual are intended to be general
installation guides for the SONARtrac Process Monitoring Systems.
They are not intended to cover the installation details for every
process due to the wide variety of applications and processes on
which the system can be used. In all cases, local safety and operating
practices should take precedence over instructions contained within
these documents.
1.2 Sensor Head Description and Function
The SONARtrac sensor head contains no moving parts. The sensor
head includes a sensor band and a fiberglass or stainless steel cover
assembly to protect the sensor band. The sensor band is wrapped
around and clamped onto the process pipe. A multi-conductor cable
electrically connects the sensors to an electronic module mounted in
the cover assembly. Signals from the electronic module exit through a
connector mounted to the outer surface of the cover assembly.
1.3 Transmitter Description and Function
The SONARtrac transmitter receives electrical signals from the sensor
head. The signals are processed using sonar array processing
firmware that displays the calculated results on an integral LCD
screen. Results can be transmitted using the 4–20mA analog output,
pulse output, alarm output, MODBUS / RTU RS-485/232 interface or
optional Foundation Fieldbus™. The electronic assembly is housed in
a rugged NEMA 4X enclosure.

The SONARtrac meter can be installed and configured with the
process in operation. Ideally, configuration is made with the process
operating at normal flow rates and operating conditions.
If the process is on-line (flowing) the following system checks should
be made.
3.2.1.1 Sensor Test
A Sensor Test all ‘ON’ sensors. (Individual sensors may be turned off
in the ‘Customize>Sensor Setup>State’ menu. Sensors should never
be turned off unless directed to do so by Technical Support
Personnel.) The test will take several seconds to perform. After the
test is completed, the screen will display test results.
A Sensor Test is made as follows:
•Press any key except ‘EXIT’ on the keypad to enter the ‘Menu
Mode’.
• The ‘Basic Config’ menu is displayed on Line 1 of the display.

Sensor Test. Repeat as necessary
•Press the ‘EXIT’ key to return to ‘Operational Mode’.
3.2.1.2 Gain
An electronic ‘Gain’ (amplification) is applied to the sensor outputs.
Transmitter based gain control functions are provided through three
sub-menus – ‘AUTOSET GAIN’, ‘CHECK/SET GAIN’, and ‘TEST GAIN’. Gain adjustments should be made to the system when the
process is operating “normally”.
The sensor head pre-amplifier gain sub-menus is accessed as follows:
3.2.1.2.1 Autoset Gain
‘Autoset Gain’ performs an automatic test and adjustment of the preamplifier gain setting. It automatically cycles through pre-determined
gain settings in order to find the optimal gain setting based on the flow
conditions at that time.
Autoset Gain is accessed as follows:
•Press any key except ‘EXIT’ on the keypad to enter the ‘Menu
Mode’.
• The ‘Basic Config’ menu is displayed on Line 1 of the display.

The current sensor minimum and maximum measurements as well
as the peak sensor values since the last peak history reset will be
displayed. A ‘!’ at the start of a line indicates that the sensor is
currently overloaded. This may indicate the sensor is not working
properly or the pre-amplifier gain is too high and should be
reduced. Pressing the ‘ENTER’ key will refresh the display.
Pressing the ‘→’ arrow key will display a prompt to erase the
sensor peak history. Press the ‘→’ arrow again to erase the peak
values.
Sensors typically have peak values of -32768 and +32767. Values

The SONARtrac transmitter implementation of HART supports HART
Universal Command Revisions 5 and 6 as well as multi-drop, with a
configurable Polling Address. It does not support Burst Mode at this
time. The SONARtrac transmitter will appear as a GENERIC device
on the HART Model 275 Handheld, for example. Most commands are
either Universal or Common Practice commands; therefore, the
SONARtrac transmitter will work with a host that can communicate
with a generic device.
DDL files exist, but have not been submitted to the HART
Communication Foundation (HCF) as of this time.
