Technology
The transit time flowmeter operates by alternately transmit-
ting and receiving a burst of sound energy between the two
transducers. The burst is first transmitted in the direction of
fluid flow and then against fluid flow.
Since sound energy in a moving liquid is carried faster when
it travels in the direction of fluid flow (downstream) than it
does when it travels against fluid flow (upstream), a differ-
ence in the travel times will occur. The sound’s travel time
is accurately measured in both directions and then used to
compute the flow rate.

Transducer Spacing
Once you entered your parameters in the previous section, the app
automatically computed the proper transducer spacing. This is shown
at the bottom of the main app screen.
The next step is to adjust the transducer spacing on the flowmeter
as follows:
. Rotate the short-wide stainless steel knob to unlock the horizon-
tal motion for each transducer.
. Move the transducers to the specified transducer spacing by slid-
ing them along the integrated ruler. NOTE: It is not necessary to
start at zero on the ruler as long as the actual spacing is correct.
. Lock into place using the short-wide stainless steel knobs. This is
important to prevent the transducer spacing from moving when
mounting the flowmeter!
Flowmeter installation
Move flat face of black
slider to the specified
transducer spacing.

Power Considerations
When recording more than 12 hours, the
Orcas must be connected to an external
power source, such as the USB power
adapter supplied with the Orcas.
Your Orcas Flowmeter battery has been fully charged at the
factory before shipping and is ready to go.* When it’s time to
recharge the battery, the app will let you know.
The flowmeter's LED light will flash while charging and will
turn itself off when complete. To maintain the life and health
of your battery, be sure to allow the flowmeter to complete
full charge cycles, i.e., continue charging until the LED stops
flashing and the flowmeter automatically turns itself off.
When using the data logging function and recording for
more than  hours, the Orcas must be connected to a
power source, such as a portable USB power bank or a USB
power adapter connected to an external power source.
* On a full charge, the Orcas will have a shelf life of up to five months. It is a good
idea to charge the unit for a full five hours if it hasn’t been used for a month or
two. On a full charge the meter should operate for up to 12 hours of continuous
use. Note that if the battery is discharged, the power button LED will blink rapidly
for five seconds and then the meter will turn off.

Flowmeter installation
Installing the Flowmeter
Do’s and Don’ts
Do charge your Orcas at least once a month.
Do allow the flowmeter to complete full charge cycles
until the LED stops flashing and the flowmeter
automatically turns itself off.
Do store your Orcas in a dry, indoor area when not in use.
Do store your Orcas fully charged.
Do keep your Orcas in its protective case when transporting
to prevent damage.
Do gently clean the transducer pads regularly with isopropyl
alcohol to prevent hardening and build up of used
coupling gel.
Don’t charge with any charger other than the W charger
supplied. Other chargers may damage the Orcas.
Don’t operate on incomplete charge or interrupt battery
charging cycles.
Don’t store, transport, or use your Orcas where the device
may exceed ˚F (˚C)— battery may leak or
explode!
Don’t bang or drop the Orcas on hard objects or surfaces.
Don’t nick the transducer pads.
Once the transducer spacing has been set and locked in
place, you are ready to install the flowmeter on your pipe.
. Rotate the tall, thin stainless knobs counter clockwise
until they stop. This raises the transducers up above
the meter footings.
. Apply coupling gel liberally to the transducer faces,
covering the entire bottom face of each transducer.
. Place flowmeter on pipe, assuring that the footings are
flush with the pipe and the meter is aligned with the
axis of the pipe.
. Strap the meter to pipe with the mounting straps,
clamping the straps into the cam cleats. Hand
tighten only!
. Rotate the tall, thin knobs clockwise to press transduc-
ers onto the pipe. Hand tighten only until seated firmly.
Warning: Tightening too much can lift the meter away
from the pipe, causing incorrect readings.
Cover bottom face of transducers with coupling gel.
Wrap cords around pipe and secure with cam cleats.
Rotate tall, thin silver knobs
counter-clockwise to
raise the transducers,
clockwise to lower.

Operation
Collecting Your Data
. Be sure the app is running on your mobile device.
. Turn on power to the flowmeter by pressing the power button on
the left top of the meter. A steady LED indicates that power is on.
The LED will flash if the meter is charging on external power.
. The app will display a list of all Orcas meters within its range. Tap
the one you are currently using.
Note: Your app will check the flowmeter to be sure it has the
most recent programming. If there is a newer version available,
it will give you the option of updating the meter. Updating the
meter may take three to five minutes.
. Your flow data will display on the Orcas App.
. When you are done collecting data, snap the cords out of their
cam cleats and you are ready to move on to your next location.
The next time you return to this location, the Orcas App will
remember your settings.

Data Logging
The purpose of the Orcas’s built-in data logger is to record flow for a
specified period of time. It may be used to conveniently record flow for as
long as  days, , measurements, or , datapoints or as little
as one minute.
While conveniently battery powered, the Orcas has limited memory. Thus,
only one data log may be used at any one time. As the Orcas data logger
uses Bluetooth (BLE) to transfer data from the flowmeter to the mobile
device, data transfer speed is limited by BLE, which is not designed to
transfer large data sets. Transferring the maximum sized data set will take
up to  / minutes.
All data logging functions are accessed by tapping the Data Logging
button in the measurement view.
The Orcas’s data logger stores only one data set at any time, selecting “REC”
(which creates a new data log) will write over the existing data log. A message
appears when selecting the “REC” button indicating that the existing data log
will be over-written if a new data log is started and gives the user the ability to
continue with the new data log or to cancel.
Operation
 SoundWater Technologies, LLC

Making a Recording
• Connect to the meter with the Orcas App.
• Tap the Data Logging button to access the data logger features.
• Using the slider bar in the app’s data logger setup view,
set the recording time.
(See Explanation of Recording Times on the next page.)
• Tap “REC” to start the recording. Data will start recording on the meter.
You can disconnect the mobile app during recording. The meter will
turn off when done to save power, unless still connected to the app.
• To stop recording prior to completing the time period, connect the
Orcas App to the meter, tap the Data Logging button, and tap “STOP.”
The status of the data logger is indicated by the color and text of the data
logger setup button, located in the measurement view. If data logger is
active, the button is outlined in red, shows a red disk drive, and displays
the text “in progress.” If the data logger is completed, the button is out-
lined in green, shows a green disk drive, and displays the text “complete.”
The data logger setup view also displays the remaining recording time for
conveniently checking progress of data logging.
Uploading Data
Data is stored on the flowmeter and may be retrieved at any time. To
upload data, the data logger must be either complete or stopped and
the app must be connected to the flowmeter. Data is uploaded using the
“Share” button located to the right of the “REC” button. Uploading the
maximum sized data set may take up to  / minutes.
If you want to quickly review your data at any time, tap the “share” button,
and then tap Quick Look (iOS devices). This displays the data log in a
spreadsheet for immediate viewing on your mobile device.
Sharing Data
You only need to upload the data log once from Orcas. Once the data
is uploaded, it may be shared any number of times without additional
uploading until a new data log is started.
Tap the “Share” button to share the data by a number of methods: email,
text, AirDrop, etc. Shared data is formatted in a CSV file (comma delimited
file). The file name is unique and contains both the date and time that the
data log was started as well as the location name. Setup information such
as the date and time the data log was started, the number of samples,
sampling period, and location name are located at the top of the data file.
The data is arranged in rows, where each row contains a single flow
measurement including sample number, time stamp, flow rate, velocity,
volume, and quality. The data file can be viewed or printed as a text file
or formatted using most spreadsheet and database programs, such as
Microsoft®Excel or Access.

The sampling period (time between recorded flow mea-
surements) and total number of recorded measurements
(samples) is controlled by Orcas. The maximum number of
measurements that can be recorded is ,, where each
measurement includes five data points (flow rate, velocity,
total volumetric flow, time, and measurement quality). The
minimum sampling period is  seconds, or in other words,
the fastest sampling rate is  samples/minute.
The Orcas data logger will minimize the sampling period
based on your selected recording time (i.e., maximize the
number of measurements). For example, if you select to
record flow for one minute, then the Orcas will set the sam-
pling period at its minimum of  seconds and will record 
flow measurements (covering a total of  seconds). If you
record flow for  days, then the Orcas again will maximize
the number of flow measurements. However, recording flow
every  seconds for  days will exceed , measure-
ments, so the Orcas will increase the sampling period to 
seconds (days /) to record , measurements.

Problem Probable Causes Things to try…
Battery not charging Using wrong power supply Use the supplied 12W charger/power supply
Incomplete battery charge Allow the flowmeter to complete full charge cycles
until the LED stops flashing and the flowmeter
automatically turns itself off
No signal Incorrect setup Confirm pipe settings
Air in pipe Rotate meter to 3 o’clock position
Remove air
Relocate meter to another location where
there is no air
Corroded rusty pipe Relocate meter to clean section of pipe. If no
clean section is available, move meter to other
locations until a signal is found—try to find a
section of pipe with less corrosion or rust.
Older steel and ductile iron pipes may be
heavily corroded, which can prevent ultrasound
transfer and flow measurements. For these
types of applications, SoundWater has a special
transducer configuration that helps to penetrate
corrosion, making flow measurement possible.
Please contact us to discuss your application and
how to select the best transducer.
