PART-1 INTRODUCTION
1.1 GENERAL
Series TF1100-EH ultrasonic flow meters feature advanced Transit-Time measuring
technology, providing accurate and reliable flow rate and total flow display, The TF1100-EH
utilizes a non-invasive transducer which is hand-held or strapped to the outside of a pipe,
which will provide benefits of non-fouling operation and ease of installation.
TF1100-EH transit time flow meters utilize 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-mode where the sound transverses the pipe two
times, W-mode where the sound transverses the pipe four times, or in Z mode where the
transducers are mounted on opposite sides of the pipe and the sound crosses the pipe once. This
selection is based 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 time interval that it takes for sound to travel between the two
transducers. The difference in the time interval measured is directly related to the velocity of the
liquid in the pipe.
1.2 APPLICATION VERSATILITY
The TF1100-EH flow meter can be successfully applied on a wide range of metering
applications. The simple to program transmitter allows the standard product to be used on pipe
sizes ranging from 20mm -6000mm internal diameters. A variety of liquid applications can be
accommodated: ultra-pure liquids, potable water, chemicals, raw sewage, reclaimed water,
cooling water, river water, plant effluent, etc. Because the transducers are non-contacting and
have no moving parts, the flow meter is not affected by system pressure, fouling or wear. Standard
transducers are rated to 85°C.
1.3 USER SAFETY
The TF1100-EH employs modular construction and provides electrical safety for the operator.
The display face contains voltages no greater than 5Vdc. All user connections are made
through sealed bulk-head plugs located on the side of the TF1100-EH enclosure.
1.4 DATAINTEGRITY
Non-volatile flash memory retains all user-entered configuration values in memory for several
years, even if power is lost or the unit is turned off. Data Logger values are stored in flash memory in
the logger. Password protection is provided as part of the Security menu and prevents
inadvertent configuration changes or totalizer resets. A time-keeper is integrated in the flow
meter for the index of date totalizing and works as the time base of flow accumulation. It
keeps operating as long as the battery’s terminal voltage is over 1.5V. In case of battery
failure, the time-keeper will not keep running and it will lose proper time values. The user
must re-enter proper time values in case the battery becomes totally exhausted. An improper
time value affects no other functions but the date totalizer.

1.5 USER FRIENDLY
The TF1100-EH features the ease of operation, high accuracy and outstanding reliability,
while the software provides a very user friendly interface and much more functions. It
employs a patent balanced lower voltage multi-pulse igniting circuit which increases the
anti-interference ability magnificently so that the flow meter will work properly even in
demanding industrial environments such as those with power frequency transmitter working
nearby. The signal receiving circuits feature self-adapting performance so as to ensure that
the user can easily operate the instrument without any adjustment. The built-in rechargeable
Ni-H battery can work continuously for more than 12 hours without recharge.
1.6 PRINCIPLE OF MEASUREMENT
The TF1100-EH ultrasonic flow meter 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 TF1100-EH transit time flow meter 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 between the transit-time is directly and exactly related to the velocity of the liquid
in the pipe, as shown in Figure 1.

PART-2 START OPERATING INSTRUCTIONS
2.1 POWER ON
Press the ON key to switch on the instrument and press the 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 time 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.
2.2 KEYPAD
The keypad for the operation of the flow meter has 16+2 keys, as shown by the right via
Keys 0 ~ 9 and .are keys to enter numbers, Key ∧/+ is the going UP key, when
the user wants to go to the upper menu window. It also works as + key when
entering numbers
Key ∨/- is the going DOWN key, when the user wants
to go down-sided menu window. It also works as the
‘–‘ key when entering numbers.
Key ◄is backspace key, when the user wants
go left or wants backspace the left character that

is located to the left of the cursor.
Key ENT is the ENTER key for any inputting or selections.
Key MENU is the key for the direct menu window jump over. Whenever the user wants
to proceed to a certain menu window, the user can press this key followed by 2-digit
numbers.
The MENU key is shortened as the ‘M’ key afterward when referring to the menu windows.
The ON key is for the power on.
The OFF key is for the power off.
2.3 MENU WINDOWS
The user interface of this flow meter comprises about 100 different menu windows that are
numbered by M00, M01, M02 … M94 etc.
There are 2 methods to enter certain menu window:
(1) Direct going/entering. The user can press the MENU key followed by two-digit number
keys. For example, the menu window M20 is for the entering of Fluid Type. The display will
go to the M20 menu window after the user presses MENU 2 0 .
(2) Pressing ∧/+ and ∨/- keys. Each time of the ∧/+ key pressing will proceed to the
lower-numbered menu window. For example, if the current window is on M12, the display
will go to the number M11 window after pressing the ∧/+ key or M13 after pressing the ∨
/- key.
There are three different types of menu windows:
(1) Menu windows for number entering, like M11 for the entering of pipe outer diameter.
(2) Menu windows for option selection/selecting options, like M14 for the selection of pipe
materials.
(3) Displaying windows only, like M00 to display Velocity, Flow Rate etc.
For number entering windows, the user can directly press the starting digit key when the user
is going to modify the value. For example, when the current window is on M11, and the user
is going to enter 154.6 as the pipe outer diameter, the user can get the numbers entered by
pressing the following serial keys: 1 5 4 . 6 ENT.
For the option selection windows, the user should first press the ENT key to a selection
modification mode and then select the relevant options by pressing the ∧/+ and ∨/- keys
or the digit keys to select the option with a number antecedent to the option. In the end, the
ENT key must be pressed to make the selection. For example, with menu window M14 for
the selection of pipe material selection, (the MENU 1 4 should be pressed first to

TF1100-EH transit-time handheld flowmeter manual

enter this menu window if the current menu window is on a different window. The pipe
material is stainless steel which has a number “1” antecedent to “stainless steel” on the
display, the user should first press the ENT key to enter into a selection modification mode,
then either make the selection by pressing the ∧/+ and ∨/- keys to make the cursor on the
line that displays “1. Stainless Steel”, or make the selection by pressing the 1 key directly.
Generally, the ENT key must be pressed to enter a modification mode. If the “Locked M47
Open’ message is indicated on the lowest line of the LCD display, it means the
modification operations is locked out. In such cases, the user should go to M47 to have the
instrument unlocked first before any further modification can be made.
2.4 MENU WINDOWSARRANGEMENT
M00~M09 windows for the display of the flow rate, velocity, date time, totalizers, battery
voltage and estimated working hours for the battery.
M10~M29 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.
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 has the most
compatibility with the previous versions of the TF1100-EH dedicated model software. This
will make it easier for the former version users with this flow meter series.
