§1.3 Principle of Measurement
The Q-FP 201 ultrasonic flowmeter is designed to measure the fluid velocity of liquid within a
closed conduit. The transducers are a non-contacting, clamp-on type, which will provide benefits
of non-fouling operation and easy installation.
The Q-FP 201 transit time flowmeter utilizes two transducers that function as both ultrasonic
transmitters and receivers. The transducers are clamped on the outside of a closed pipe at a specific
distance from each other. The transducers can be mounted in V-method where the sound
transverses the pipe twice, or W-method
where the sound transverses the pipe four times, or in
Z-method where the transducers are mounted on opposite sides of the pipe and the sound crosses
the pipe once. This selection of the mounting method depends on pipe and liquid characteristics.
The flow meter operates by alternately transmitting and receiving a frequency modulated burst of
sound energy between the two transducers and measuring the transit time that it takes for sound to
travel between the two transducers. The difference in the transit time measured is directly and
exactly related to the velocity of the liquid in the pipe, show as follows:

2. Starting Measurement
§2.1 Built-in Battery
The instrument can operate either from the built-in Ni-H rechargeable battery, which will last over
12 hours of continuous operation when fully recharged, or from an external AC/power supply from
the battery charger.
The battery charging circuits employ a scheme of constant-current and constant-voltage. It has a
characteristic of fast charging at the beginning and very slow charging when the battery approaches
to full recharge. Generally, when the green LED starts coming on, the battery would be nearly 95%
recharged and when the red LED is off, the battery would be 98% recharged.
Since the charging current becomes tapered when the battery recharge is nearly completed, i.e. the
charging current becomes smaller and smaller, therefore, there should be no over-recharging
problem. That means the charging progress can last very long. The charger can be connected to the
handset all the time when an around-the-clock measurement is required.
When fully recharged, the terminal voltage reaches around 4.25V. The terminal voltage is displayed
on window M07. When the battery is nearly consumed, the battery voltage drops to below 3V. The
user can obtain an approximate battery working time from the battery voltage.
A software battery working time estimator is integrated in this instrument based on the terminal
voltage. Please note that the estimator may have relatively bigger errors in the estimated working
time, especially when the voltage is in the range of around 3.70 to -3.90 volt.
§2.2 Power On
key to switch on the instrument and press the I OFF to turn off the power.
Once the flow meter is switched on, it will run a self diagnostic program, checking first the
hardware and then the software integrity. If there is any abnormality, corresponding error messages
will display.
Generally, there should be no display of error messages, and the flow meter will go to the most
commonly used Menu Window Number 01 (short for M01) to display the Velocity, Flow Rate,
Positive Totalizer, Signal Strength and Signal Quality, based on the pipe parameters configured last
ti me by the user or by the initial program.
The flow measurement program always operates in the background of the user interface. This
means the flow measurement will keep on running regardless of any user menu window browsing
or viewing. Only when the user enters new pipe parameters will the flow meter change
measurement to the new parameter changes.

When new pipe parameters have been entered or when the power has been just switched on, the
flow meter will enter an adjusting mode to make the signals magnified with proper amplification.
By this step, the flow meter is going to find the best threshold of receiving signal. The user will see
the progress by the number 1, 2, or 3, which are indicated on the right lower corner of the LCD
display.
When the transducers have been adjusted on the pipe by the user, the flow meter will re-adjust the
signal automatically.
Any user-entered configuration value will be retained into the NVRAM of the flow meter, until it is
modified by the user.

Examples of optimum locations.
Principles to selection of an optimum location
(1)
Install the transducers on a longer length of the straight pipe. The longer the better, and make
sure that the pipe is completely full of liquid.
(2)
Make sure that the temperature on the location does not exceed the range for the transducers.
Generally speaking, the closer to the room temperature, the better.
(3)
Take the pipe fouling into consideration. Select a straight length of a relatively newer pipe. If
the condition is not satisfying, consider the fouling thickness as part of the liner for a better
result.
(4) Some pipes have a kind of plastic liner, and between the outer pipe and the liner there may be a
certain thickness difference that will prevent the ultrasonic waves from direct traveling. Such
conditions will make the measurement very difficult. Whenever possible, try to avoid this kind
of pipes. If impossible, try our plug-in transducers that are installed permanently on the pipe by
drilling holes on the pipe while liquid is running inside.
§2.7 Transducers Installation
The transducers used by the Q-FP 201 eries ultrasonic flow meter are made of piezoelectric
crystals both for transmitting and receiving ultrasonic signals through the wall of liquid piping
system. The measurement is realized by measuring the traveling time difference of the ultrasonic

signals. Since the difference is very small, the spacing and the alignment of the transducers are
critical factors to the accuracy of the measurement and the performance of the system. Meticulous
care should be taken for the installation of the transducers.
Steps to the installation of the transducers
(1)
Locate an optimum position where the straight pipe length is sufficient, and where pipes are
in a favorable condition, e.g., newer pipes with no rust and ease of operation.
(2)
Clean any dust and rust. For a better result, polishing the pipe with a sander is strongly
recommended.
(
3
)
Apply adequate coupler to the spot where the transducers are to be installed and leave no gap
between the pipe surface and the transducers.
Extra care should be taken to avoid any sand or dust particles left between the pipe outer surface
and the transducers.
To avoid gas bubbles inside the upper part of the pipe, the transducers should be installed
horizontally by the side of the pipe.
§2.7.1 Transducers Spacing
The spacing value shown on menu window M25 refers to the distance of inner spacing between the
two transducers. The actual transducers spacing should be as close as possible to the spacing value.
§2.7.2 V-method Installation
V-method installation is the most widely mode for daily measurement with pipe inner diameters
ranging from 15 mm to 400 mm. It is also called reflective mode.

§2.8 Installation Checkup
Through the checkup of the installation, one can: check the receiving signal strength, the signal
quality Q value, the traveling time difference of the signals, the estimated liquid speed, the
measured traveling time of the signals and the calculated traveling time ratio. Therefore, optimum
measurement result and longer running time of the instrument can be achieved.
§2.8.1 Signal Strength
Signal strength indicates the amplitude of receiving ultrasonic signals by a 3-digit number. [000]
means there is no signal detected and [999] refers to the maximum signal strength that can be
received.
Although the instrument works well if the signal strength ranges from 500 to 999, stronger signal
strength should be pursued, because a stronger signal means a better result. The following methods
are recommended to obtain stronger signals:
(1)
Relocate a more favorable location, if the current location is not good enough for a stable and
reliable flow reading, or if the signal strength is lower than 700.
(2)
Try to polish the outer surface of the pipe, and apply more coupler to increase the signal
strength.
(3) Adjust the transducers both vertically and horizontally while checking the varying signal
strength, stop at the highest position, and then check the transducers spacing to make sure the
transducers spacing is the same as what the M25 shows.
§2.8.2 Signal Quality
Signal quality is indicated as the Q value in the instrument. A higher Q value would mean a higher
Signal and Noise Ratio (short for SNR), and accordingly a higher degree of accuracy would be
achieved. Under normal pipe condition, the Q value is in the range 600-900, the higher the better.
Causes for a lower Q value could be:
(1)
Interference of other instruments and devices such as a powerful transverter working nearby.
Try to relocate the flow meter to a new place where the interference can be reduced.
(2)
Bad sonic coupling for the transducers with the pipe. Try to apply more coupler or clean the
surface, etc.
(3)
Pipes are difficult to be measured. Relocation is recommended.
§2.8.3 Total Transit Time and Delta Time
The numbers displayed on menu window M93 are called total transit time and delta time
respectively. They are the primitive data for the instrument to calculate the flow rate inside the pipe.
So the flow rate indication will vary accordingly with the total time and delta time.
The total transit time should remain stable or vary little.
If the delta time fluctuates higher than 20%, it means there are certain kinds of problems with the
transducer installation.

§2.8.4 Time Ratio between the Measured Total Transit Time and the Calculated
Time
This ratio would be used to check the transducer installation. If the pipe parameters are entered
correctly and the transducers are installed properly, the value for this ratio should be in the range of
100±3. If this range is exceeded, the user should check:
(1) If the pipe parameters are correctly entered.
(2)
If the actual spacing of the transducers is right and the same as what the window M25 shows.
(3) If the transducers are installed properly in the right directions.
(4)
If the mounting location is good and if the pipe has changed shape or if there is too much
fouling inside the pipes
Other poor

§3.1 Menu Windows Arrangement
MOO—M09 windows for the display of the flow rate, velocity, date time, totalizers, battery voltage
and estimated working hours for the battery.
M10-1\429 windows for entering the pipe parameter.
M30—M38 windows for flow rate unit selections and totalizer unit selections.
M40—M49 windows for response time, zeroing, calibration and modification password setup.
M50—M53 windows for the built-in logger
M60-M78 windows for time-keeper initialization, version and ESN information viewing and
alarms.
M82 window for viewing date totalizer.
M90—M94 are diagnostic windows for a more accurate measurement.
M97—M99 are not windows but commands for the outputting of display copying and pipe
parameter setups.
M+0—M+8 are windows for some additional functions, including a scientific calculator, viewer on
records such as total working hours, turn-on and turn-off times, dates and times when
the flow meter has been turned on or turned off.
Other menu windows such as M88 have no functions, or functions were cancelled because they are
not applied to this version of the software.
The major reason why the menu windows are arranged in this way is that the software programmer
hopes that the menu window arrangement for this version can be compatibility with the previous
versions of the flow meter software. This will make it easier for the former version users with this
flow meter series.

4. How To
§4.1 How to judge if the instrument works properly
When 'R' is displayed in the lowest right corner of LCD display, the instrument is working properly
generally speaking.
If an
flashes on that place, there could be poor signal received. Please refer to the chapters on
diagnosis.
If an T is displayed, it means that there is no signal detected.
If a `.1' is displayed, it means that the hardware of this instrument could be out of order. Refer to the
chapter on diagnosis.
§4.2 How to judge the liquid flowing direction
(1) Make sure that the instrument works properly
(2)
Check the flow rate for the indication. If the displayed value is POSITIVE, the direction of
the flow will be from the RED transducers to the BLUE transducers; if the displayed value is
NEGATIVE, the direction will be from the BLUE transducers to the RED transducers;
§4.3 How to change between units systems
Use menu window M30 for the selection of unit system in English or Metric system.
§4.4 How to select a required flow rate unit
Use menu window M31 to select the flow unit first and then the timing unit.
§4.5 How to use the totalizer multiplier
Use window M33 to select a proper totalizer. Make sure that the totalizer pulse is appropriately
speeded. It should not be too fast and neither too slow. A speed of producing a pulse in several
seconds or minutes is preferable.
If the totalizer multiplier is too small, there can be a loss of accumulation pulse because the output
device can output only one pulse in a measurement period (500milliseconds)
-21-
If the totalizer multiplier is too large, the output pulse will be too fewer for the devices that are
connected with the instrument for a quicker response.
