General Information
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 silver knob to unlock the horizontal 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, so long as the actual spacing is correct.
. Lock into place using the short wide silver knobs. This is im-
portant to prevent the transducer spacing from moving when
mounting the flowmeter!

Flowmeter installation
Installing the Flowmeter
Do’s and Don’ts
Do store your Cypress in a dry, indoor area when not in use.
Do keep your Cypress 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 store, transport, or use your Cypress where the
device may exceed ˚F (˚C).
Don’t bang or drop the Cypress 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.
. Thread the stainless steel mounting straps through the
access ports located on either side of the flowmeter.
. Rotate the tall thin silver 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,
securing the straps with a socket or flat head driver.
. Rotate thin silver 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.
Rotate tall thin silver knobs counter-clockwise
to raise the transducers, clockwise to lower.
Cover bottom face of transducers with coupling gel.
Secure flowmeter to pipe

Collecting Your Data
. Be sure the app is running on your mobile device and the flowmeter
is plugged into a power source. .
. The app will display a list of all Cypress flowmeters 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 Cypress's built-in data logger is to record flow for a speci-
fied 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.
Cypress has limited memory. Thus, only one data log may be used at any
one time. As the Cypress 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.
Cypress’s data logger stores only one data set at any time. Selecting “REC”
(which creates a new data log) will overwrite 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.

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 Cypress. 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 Cypress. 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 Cypress 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 Cypress will set
the sampling period at its minimum of  seconds and
will record  flow measurements (covering a total of 
seconds). If you record flow for  days, then the Cypress
again will maximize the number of flow measurements.
However, recording flow every  seconds for  days will
exceed , measurements, so the Cypress will increase
the sampling period to  seconds (days /) to
record , measurements.

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.
