Chapter 1 Introduction
1.1 Preface
Welcome to the SUP-2100H series ultrasonic flow meter that has been
manufactured with patent technologies and is equipped with more functions and
advanced performance than our previous versions.
The ultrasonic flowmeter has been upgraded on the basis of the previous version,
and the new version retains most of the excellent features and functions of the
previous version: pulse measurement technology, ultrasonic ignition and small
signal receiving circuit, etc. Major improvements have been made to the battery
powered circuit and the transmitter circuit. Since we have applied state-of-the-art
measurement techniques and obtained a more reliable model of the ultrasonic
flowmeter, all other circuits are simply integrated into this new version without
major modifications.
The SUP-2100H series flow meter incorporates the latest ICs manufactured from
the famous semiconductor manufacturers like Philips, Maxim, TI, win bond, and
xilinx. The hardware 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 transverter working nearby.
Other outstanding features:
----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 l2
hours without recharge.
The advanced circuit design, the integration of the latest semiconductors, the
user-friendly software interface both in English and Chinese languages and
small-sized PCB board, all these features combine to make the SUP-2100H series
ultrasonic flow meter the best and the biggest seller on the market.

1.3 Principle of Measurement
The SUP-2100H 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 SUP-2100H 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 in the transit time measured is directly and exactly
related to the velocity of the liquid in the pipe, as shown in Figure l.

1.5 Typical Applications
The SUP-2100H flow meter can be virtually applied to a wide range of
measurements. The measured pipe ranges 20-6000 mm [0.5 - 200 inch]. A variety
of liquid applications can be accommodated: ultra-pure liquids, potable water,

Chapter 2 Starting Measurement
www.supmea.com

chemicals, raw sewage, reclaimed water, cooling water, river water, plant effluent,
etc. Because the instrument and transducers are non-contacting and have no
moving parts, the flow meter can not be affected by system pressure, fouling or
wear. standard transducers are rated to 110℃. Higher temperatures can be
accommodated. For further information, please consult the manufacturer for
assistance.
1.6 Data lntegrity and Built.in Time.Keeper
All user-inputted configuration values are retained in the built-in non-volatile flash
memory that can store them for over 100 years,even if power is lost or turned off.
Password protection is provided to avoid 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.
1.7 Product ldentification
Each set of the SUP-2100H series flow meter has a unique product identification or
ESN written into the software that can only be modified with a special tool by the
manufacturer. In case of any hardware failure, please provide this number which is
located on menu window number M61 when contacting the manufacture.

2.1 Built.in Battery
The instrument can operate either from the built-in Ni-H rechargeable battery,
which will last over l0 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

Chapter 2 Starting Measurement
www.supmea.com
9
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
Press the key to switch on the instrument and press the 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 0l (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

Chapter 2 Starting Measurement
www.supmea.com

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.
2.3 Keypad
The keypad for the operation of the flow meter has l6＋2 keys, as shown by the
right dia
Keys 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 is the ENTER key for any inputting or selections.
Key is the key for the direct menu window jump over. When ever the user
wants to proceed to a certain menu window, the user can press this key followed
by 2-digit numbers.
The key is shortened as the‘M' key afterward when referring to the menu
windows.
The key is for the power on.
The key is for the power off.
2.4 Menu windows
The user interface of this flow meter comprises about l00 different menu windows
that are numbered by M00, M01, M02 . M99.
There are 2 methods to enter certain menu window:
(1) Direct going/entering. The user can press the key followed by two-digit
number keys. For example, the menu window M11 is for the entering of pipe outer

Chapter 2 Starting Measurement
www.supmea.com
11
diameter. The display will go to the M11 menu window after the user
presses.
(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.
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 Ml4 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 219.2345 as the pipe outer diameter, the
user can get the numbers entered by pressing the following serial keys:.
For the option selection windows, 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 select the option with a number antecedent to the option. In
the end, the key must be pressed to make the selection. For example, with
menu window M14 for the selection of pipe material selection, (the should
be pressed first to enter this menu window if the current menu window is on a
different window. The pipe material is stainless steel which has a number "l"
antecedent to "stainless steel" on the display, the user should first press the
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 key directly.
Generally, the 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
