1. Must-knows about TDS-100M
Please the users must read the following paragraphs when you use TDS-100M for the first time
The setup of a TDS-100M ultrasonic flow converter needs one of the three tools. The first tool is a parallel
LCD and keypad module which can be connected to the 20 Pins port. The second tool is a serial LCD and
keypad module which can be connected to the RS232 port. The third one is a PC-based software (under
development), by means of the software, the parameters that TDS-100M needs to work properly could be
downloaded by use of the RS232 port on the PC. If your computer does not have a RS232 port, you need to
buy a USB-RS232 converter.
（1）All setup parameter data are stored in the RAM memory temporally. Users need to solidify the
parameters, when setups are been finished, that is to store the parameter to the internal flash memory. Go to
Menu26, Select the option that says “make default paras” then pressing the ENT key will start the progress
of storing. If the current parameters are different with that in the flash memory, the system will store your
current parameters into the flash memory and then boot again. By doing so, the parameters will always be

get lost, even when both the power supply and the backup battery are removed.
（2）The zero point, that is the indicated flow under the situation of motionless liquid, has a great influence
over the linearity and accuracy of the flow meter. Users should try every possibility to perform the Zero
Setup that is located at Menu 42. Zero setup should always been performed under the condition of
motionless liquids. If Zero setup was been performed with motion of the liquid, you can use Menu 43 to
restore to the original zero point. The zero point will be stored in the RAM memory temporally when you
use Menu 42. If you want to solidify the zero point, you need to perform Menu 26 “make default paras”
function again. If this step was omitted, the system will override the RAM zero point by restoring the zero
point that is stored in the flash memory with next power-on.
（3）The internal calendar is the base of date accumulators. Incorrect date and time will cause messy
records with the date accumulators. Please the user check the calendar by input correct date and time. The
calendar runs relying on the backup battery when there is no 24VDC supply. When the battery voltage is
less than 2 volts, a new backup battery should be replaced with. Replacing the battery with a new one
should be performed with the 24VDC applied so that the accumulator data and calendar data will not get
lost.
（4）Please pay great attention to the power supply. The applied voltage should be in the range of +15V to
24VDC, or 15V to 20VAC. Avoid applying a 110VAC or 220VAC power forever, or the module will be
damaged.
（5）Pay attention to the display located on Menu 48, which shows the points of lines for the linearity
correction function. 0 stands for shutting off the function. The default value is 0. Try to make sure that
value is 0 so as to avoid abnormal flow.
（6）The latest calibrated data which are produced by performing the analog input or output calibration are
store in the RAM memory temporally. Users need to perform the M26 function to make these data be
solidified.
（7）Use Menu 49 to check if there are inputs from the RS232 port with network application. If not, please
check protocol selection software switch located at Menu 63 and the serial port parameters options located
at Menu62. Select option 1 at Menu 63 for the MOSBUS RTU application. Select option 0 for MODBUS
ASCII and FUJI extended and Simple Water Meter protocols.
（8）By a flash of the LED indicator for every 2 seconds, TDS-100M means the meter work properly. A
short flash for every second indicates no-signal or poor signal condition and a long flash for every second
shows the meter is performing a receiving gain adjusting.
2. Introduction to TDS-100M
(1) Development introduction
The TDS-100M is a compact, high performance general purpose ultrasonic flow meter module. The
design of the meter is intended to provide for users like system integrators and OEM users with a lowest
cost but of high performance flow meter. The development of the meter is based on a widely used flow
meter made by this company. The meter uses only one high performance MSP430 series microprocessor
made by Taxes Instruments.
This module can work alone without a LCD and Keypad module. The parameters that the flow meter
needed to work properly can be (1) setup by a parallel keypad module witch will be plugged onto the
parallel interface inside of the module, or by a serial keypad module witch will be plugged onto the

RS232C or RS485 port of the meter. (2) downloaded by use of a PC computer based software (the software
is under development now).
The transducers can be one the all kinds of the types made by this company, include the clamp-on type,
the insertion type, the PI- type and standard-pipe type. It can even use transducers by the users or the
transducers made by other company.
The module will satisfy the measurement requirement for most kind of liquids, such as water, sea
water, sew water and chemistry liquids. It can even measure pure paper pulp or fluids with higher density
suspend particles.
The module can be used alone as a flow meter. Users can even integrate a number of the modules into
a multi-channel flow meter that can measures up to several dozen of different pipes or a flow meter that has
higher accuracy by measures the same pipe with all the channels.

§4.1 Unpack checking
Check whether the spare parts comply with packing list,enclosure is broken or not during
transportation?did screw drop?connecting line is loose or not?if have questions,pls cotact factory.
§4.2 Power supply and cable
When users place an order,pls inform factory what kinds of power supply is
needed,normaly the power supply of the flow meter have following options:
: DC24V or DC8~36V
Transducers signal cable of TDS-100M series ultrasonic flow meter adopts high frequency special
shielded twisted pair cable.because sending and receiving circuit adopts balanced transmitting
and balanced receiving principle.so to increase the anti-interference function,little signal
consumable ,ensure the device work well in longer term.so the special signal cable supplied by
factory is the best choice for you.if using coaxial shielded radio frequency cable or poor quality
twisted pair cable,it could lower accuracy and the function of the device.when there is bigger
interference signal from outside,the device could not measure normally.
§4.3 Required installation condition
Installation of The new TDS-100M series is the easiest and convenient way in the
installation of all flow meters,just choosing a suitable measurement point,input the pipe
parameters of this pipe point to the flow meter,then fix the transducers on the pipe.
§4.3.1 choosing measurement point
To ensure measurement accuracy and stability,the installation point of tranducers should be on
the straight pipe full of well distributed fluid(when installing,the pipe must be full of liquid),comform
to following principle:
1.Pipe must be full of liquid that is uniform and easy to travel the ultrasonic beam(vertical pipe or
horizontal pipe)
2.Upstream transducer should be installed at the place where the upstream length of the straight

TDS-100M Manual
13
pipe is at least 10D and the downstream length is at least 5D where install the downstream
transducer,so the pipe length should be straight without any valve,pump,angle head, D stands for
pipe ouside diameter. The installation point should stay away from valves,pump,high pressure
current,transformers interference source etc.
3.Avoid to install on the highest point of pipe system or vertical pipe with free exit(flow down)
4.For the opened pipe or half full pipe,the transducers should be installed on U pipe.
5.The temperature and pressure on the installation point should be within the work ability of the
transducers.
6.Pay more attention to the pipe scaling in inner pipe wall,do best to choose the pipe without
scaling to install,if it is impossible ,then consider the scaling as liner to achieve better accuracy.
7.The two transducers must be installed in horizontal direction to pipe axis plane,within ±45°of axis
line horizontal plane, to prevent bubbles or not full in upper pipe or sediment in down side of pipe
to influence transducer measurement normaly.if there is space limit of installation that could not
install horizontal symmetry,then install the transducers vertically or dip angle under the condition of
no bubbles in upper parts of pipe.

TDS-100M Manual
14
§4.3.2 instrument well construction requirements
If need to install transducers in instrument well,there must be enough installation room,convenient
for people to stand up to work,distance between pipe wall and well wall is at least above
550mm,width is more than (D+550*2)mm,cement pipe width is more than
(D+700*2)mm,instrument well axial width L is more than D+1200mm.when installing
transducers,avoid the place of flange,welding line,reducing,do best to install transducers in the
range of +/-45° of horizontal position of pipe axis.
Attention:1,Do best to install transducers in the range of +/-45° of horizontal position of
pipe axis .

§4.5.1 Installation space
Installation space of clamp on type transducer is inner edge distance of the two transducers(face
to face),after inputing the required parameters in Menu,check the display on M25,that is the
installation space.
§4.5.2 Installation method
The method has 2 kinds: V method,Z method
Normaly,V method is suitable to the pipe diameters within the range: DN15-DN200mm .when
using V method can not measure the signal or the signal is poor,try to use Z method that is
suitable to the diameters are more than DN200mm or measuring cast iron.
V method(commonly used method)
Normaly,V method is standard installation method,convenient to use with precise
measurement,when installation,the two transducers horizontally align,its centre line is horizontal
with pipe axis line,suitable pipe diameter range to measure is DN15mm-DN400mm。
Z method (the most commonly used method)
When the pipe diameter is wide,or there are suspended matters in fluid,too thick scaling or
liner inside pipe inner wall,that can make the flow meter can not work normaly and signal poor by
using V method installation,so need to use Z method to install,its features are direct transfering
without reflection(called sigle sound path),little signal attenuation.
Attention:1,when installation,it is a must to clear the pipe area where to install
transducers,showing metal color
2,shield line of ultrasonic signal cable can not be connected,but not short circuit with positive

3,after transducers are connected with circuits,must apply enough sealant to prevent water in.
4,after covering the transducers,must screw and lock tightly the hole for shield line of
transducers to prevent water in.
5,use strap(stainless steel band) to fix on the center part of transducers,to make it weighted
uniform,no moving.
6,apply enough couplant around the area ，so that transducers touch pipe to prevent
air,sands,rust in,that influence the beam transfering.
§4.6 Insertion type transducer installation method
The new TDS-100M series insertion type transducer incorporates the advantages of clamp on
type and in line type transducers,its features:
Transducers can be installed directly on pipes of carbon steel or stainless steel by welding;
while for those pipes of materials like cast iron, glass fiber reinforced plastic, PVC and cement
which cannot be welded directly, special straps should be used for installation. For
those users who are in similar situation, please inform us of the precise outside diameter
of the pipe to be installed to prevent leakage.

§4.6.1 Installation tools
Special hole-drilling positioning tools made by our company (Hipeak Instrument Development Co.,
Ltd), 400w handle rotary drill (high speed adjustable is preferable), spanner and
screwdriver are needed for installing insertion transducers.
§4.6.2 Installation space
Insertion style transducers spacing is calculated based on the distance between the centers of the
two transducers along the pipe axis. The space will be shown on menu M25 when necessary data
are put into the menu, and the transducers should be installed according to this space.
§4.6.3 Installation method
There is only one way to install insertion style transducers which is called Z-method installation
and can be applied for all pipes which diameter is more than DN80mm.
§4.6.4 Locate the installation point
Input the pipe parameters on the mainframe, the installation space L (L=inside diameter－
9.113mm) will be calculated. (the two sensors must be located in the same axis plane), the
installing space L should be the distance between the centers of the two sensors horizonally.

long and 200mm (or D) wide rectangular paper (according to actual situation on spot,
the paper tape can also be replaced by moisture-and-corrosion resistant materials), and draw
a line about 100mm from the edge;
B. Wrap the fixed position paper on the cleaned surface of the pipe, making sure that the two
paper sides are overlapping and aligned and thus the line drawn may be parallel with the pipe
axis;
C. Extend the line on the fixed position paper to the pipeline and the
cross-point between the vertical side of the fixed position paper and the extended line is A
D. Starting from A and along the edge of the position paper, the length of half of the pipe perimeter
is measured and the cross point is C; then draw a line at C to be parallel to the axis (that is, to be
parallel with the line on the position paper);
E．Removing the fixed position paper and starting from C, the installation space L should be
measured along the line, draw on the pipe ,the point is B. Thus, A and B are the points where the
transducers are to be installed. For example, L=280mm. Then two bases of ball valves should be
welded respectively on A and B, making sure the centers of bases overlap A and B respectively.

TDS-100M Manual
19
§4.6.5 Welding the base of the ball valves
For pipes that can be welded (such as steel and stainless steel, etc.), just weld the base on the
pipe (Stainless steel pipe should be welded to stainless base, please indicate in
your
order). Before welding, the rust and paint on the section where the sensors are to be installed shall
be
cleaned up by using an angle grinder, and the oil dirty and dust should be cleaned by using
acetone or
alcohol. to prevent water leakage,so the work of welding is very important, making sure the
centers of bases overlap A and B respectively,no air bubbles.
For pipes which material cannot be welded directly (such as cast iron and cement, etc.), special
hoops
(with airproof rubber pads) should be used. The bases of the ball valves have been welded on the
hoops.
These hoops are directly fixed on the pipe and make sure that the centers of the ball valves
overlap A
and B respectively. Finally, the ball valves should be closely fixed on the bases welded on the
hoops to
prevent water leakage.
§4.6.6 hole-drilling
Connect the sealed sheath of the hole-drilling machine and the outer screw thread of the
tailor-made ball valves,screw tightly,open the ball valves,push the drill pipe to touch the outer
surface of pipe;
then the drill pipe shall be locked to the handle rotary drill before the drill is switched on. During
drilling,
the drill machine should work in a low speed to avoid sticking or even drill bit breaking.after drilling
through pipe wall,pull back the drill pipe until the head of drill bit reach the ball valves spool,turn off
the ball valves,take down hole-drilling machine. ①Pipe

through the ball valve to ball valve spool. Open the ball valve and continue to screw the transducer
until the head of transducer passes the inner wall of the pipe. Before the wires
are connected, the angle of the transducer should be adjusted to make sure that the head of two
transducers can be in face to face position so as to send and receive the signals properly(the hole
for line of two transducers should be upward or downward at same time).and then fix the screw
mut,connect the wires,use silicon rubber to seal the connection place.
§4.6.8 Length calculation of the part of transducer into the pipe inner wall:
Insertion style transducer is made of stainless steel by casting. As the transducer's length A and
the pipe wall's thickness B are known, and the length part of transducer left
outside the pipe can be measured, the length of the inner part of the transducer can be
calculated through the formula: L=A-B, C=0
Note: the length A of different types of transducers are: Standard insertion type B: A=170mm;
Standard insertion type C: A=220mm, and Cement insertion type B: A=310mm.
§4.6.9 wiring
After wires being connected, screw the mut on the hole for wires (do not lose packing seal),at
last,screw seal cover tightly to prevent water leakage.

§4.6.11 Maintenance
The maintenance is easy,exchange the old transducer with the new transducer according to the
reverse process.
Attention:
1 during the process of welding the base of the ball valves,avoid the phenomenon of slag
inclusion,sand hole,water leakage.
2. The bases of the two ball valves should be welded on the same axis plane
to prevent poor receiving of ultrasonic waves;
3. after The holes having been drilled through, the impurities such as iron filings in the ball
valve should be cleaned
up so that the transducer probe may not get stuck or its thread get adhered;if so,still to screw
hardly,and do not stop,the transducer will be destroyed and not work well.
4. Make that the ultrasonic emitting surfaces of the two transducers are face to face (that
is, the holes for wires are in the same direction and either upward or downward);
5. After the transducer is installed, the screw mut should be screwed tightly to avoid
transducer move.
The seal cover should be screwed tightly to prevent water after wires being connected..
§4.7 In-line type transducer installation method
In-line type transducer of new TDS-100M series is characterized by easy installation and
high-accuracy measurement. When ordering, customers need to provide the actual parameters of
the pipe. The parameters of the transducer have been put into the flowmeter before leaving factory
and there is no need to input them when installing.
There are two types of pipe transducers for selection:
1. π-type transducer(DN15-DN40MM)
2. Standard pipe transducer(DN50-DN1000MM)
Parameters π-type transducer Standard pipe transducer
Material Stainless steel Carbon steel(stainless steel is optional)
