§1.2 Principle of Measurement

When the ultrasonic beam is transmitted through the flowing liquid, there will be a difference between the upstream and downstream transit time (travel time or time of flight), which is proportional to flow velocity,when fluid is flowing,counterflow transit time is more than direct flow transit time. the formula as below.

§3.1.3 Work parameter solidification of the flow meter and option introduction

The new TDS-100F has 3 work parameter areas.respectively called:present parameter data block,solidification parameter data block,user pipe parameter data block.

Present parameter data block is built in internal RAM,if outside power supply and spare battery are off together,then lost the present work parameter.

Solidification parameter data block is built in internal FLASH,normaly it will not loose.

for long time stable work application,after setuping all the work parameters,using the function of solidification parameter in M26 to solidify the parameter data block in RAM to

FLASH,and setup recalling the work parameter in FLASH to present parameter data block when power on for each time.for the application of modifying the parameters frequently(like portable flow meter),pls choose “0. use parameter in RAM area”option in M26.when power on,then keep the parameters in RAM to use directly.if the data block in RAM exists verification errors,then it will go on to recall the work parameter in FLASH

User parameter data block is able to store 9 sets commonly used pipe parameters.the access operation is in M27

§3.1.4

Zero point setup and zero point solidification

The new transducers have a “zero point”,its meaning is when fluid flow velocity is zero,the flow meter will display a non-zero flow value.this value will repeated add to indicating value of the flow meter under any flow velocity,for example,assume that the zero point is

1m3/h,present flow velocity is 10m3/h,then the indicating value of the flow meter is 11m3/h.so

newly install or change transducers,normaly need to adjust zero point and log zero point value,minus this zero point value from indicating value for calculating later.

To adjust zero point in M42.but the zero point value after adjusting is only stored in RAM parameter area temporarily ,is not solidified in FLASH.if the spare battery is off or choosing the solidification parameters in FLASH as work parameters when power on,the zero point value will loose.in order to keep the zero point value forever,users must use M.2 to store the zero point after adjusting zero point for each time.

§3.1.5 Factory use the scaling factor solidification

Same as the priciple of storing zero point value,factory scaling factor need be solidified after calibration before leaving factory.it is in M.1 ,use two grade passwords to visit.

§3.1.6 analogue calculating function application

When setuping pipe diameter is zero,display the instant flow velocity :1.2345678m/s(4.0504ft/s),instant flow rate=0 ,and display “R”status.inputing

a set value in M44 can obtain changable totaliser output.using this function to achieve the function of test of the flow meter and adjustment of network software without connecting transducers.

TDS-100P MANUAL

§3.1.7Analogue input interface as digit input interface method and introduction

The new TDS-100P series’ analogue input interface can work as digit input interface ,but note that the loop input current should not be over 20 mA.when outer digital quantity voltage is 5V,you should series connect a 1k resistor in return circuit.if the digital quantity voltage is 12V,then series connect a 2k resistor.

§3.1.8 Introduction of serial peripheral extention interface

Serial peripheral extention interface is like USB interface,it has input,output,power supply+,power supply- ,totally 4 lines.for each measuring,it can output instant flow,instant heat flow,positive total,4-20mA value,frequency value and printing data etc.different

function model can take down datas according to requirements.the serial bus use 4800 baud rate.

§3.1.9 Realize medium identifying function

For example:application in mixture fluid of oil and water,to judge the medium in pipe is water or oil,you could input lower limit of water flow in M+6,it is 1400m/s for this example.when the fluid flow velocity measured by the flow meter is lower than 1400m/s,a internal signal created,used to indicate that the fluid is another medium.this signal can be output by OCT or read by MODBUS protocol.but you assure that the two fluid flow velocity can not exist overlap.

§3.2 The flow meter restore to factory default

If like to clear all set parameters to restore original factory default,only use serial port or parrallel port keyboard to enter M37 to click <•>< ◄>,so can restore default set parameters before leaving factory.

Attention:except of first installation,normaly not use this function.

4.transducers installation

§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,please contact factory.

§4.2 Power supply and cable

When users place an order,please inform factory what kinds of power supply is needed, normally the power supply of the flow meter have following options:

220VAC recharger.

Battery can be working for 24 hours continuously

.

:Draw operator attention: if connect the mainframe powered supply by direct current or low voltage AC (DC8-36V) with AC220V,the flow meter will be destroyed.

Transducers signal cable of TDS-100P 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.

TDS-100P MANUAL

§4.3 Required installation condition

Installation of The new TDS-100P 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 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.

14

TDS-100P MANUAL

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.

15

TDS-100P MANUAL

§4.3.2 instrument well construction requirements

§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

§4.6 Insertion type transducer installation method

The new TDS-100P 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

21

TDS-100P MANUAL space L should be the distance between the centers of the two sensors horizonally.

A.

Making a fixed position paper: take a 4D (D refers to the pipe inner diameter) 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

22

TDS-100P MANUAL 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.

§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

23

TDS-100P MANUAL 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.

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.

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.

§4.6.10 Transducer wiring picture

§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-100F 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)

§4.8

check installation of transducers

After the completion of transducer installation, the user should check the following items to see whether the installation is suitable,whether the received ultrasonic signal is correct,enough strong,that could make the meter work normaly and long time running. By checking the receiving signal strength S, the signal quality Q value, the delta time, , the transit time ratio R to assure whether the installation point is good or not. Normaly,apply couplant on the transducers and attach them on the pipe ,so can obtain measurement results,but it is better to chech followings to ensure the flow meter is working properly and the results are reliable and accurate.

§4.8.1 Signal Strength

Signal strength S (display on M90) indicates strength of sending and receiving signals from upstream transducer and downstream transducer by a 3-digit number.

[00.0] means there is no signal detected, and [99.9] refers to the maximum signal strength that can be detected. When installation,do best to adjust the position of transducers and check whether the couplant is sufficient,to make sure to gain the strongest signal.Although

the instrument works well when the signal strength ranges from 60 to 99,when the signal strength is too low,you should chech the installation position ,installation space,whether the pipe is suitable to install or change to install by Z method. stronger signal strength should be pursued, because a stronger signal means a stable measurement results,long and reliable running..

§4.8.2 Signal quality(Q value)

:Signal quality is indicated as the Q value(display on M90) that represent the receiving signal is good or not,TDS-100F series use 00-99 digits to represent signal quality.00

represent the worst signal,99 represent the best signal,normaly the signal quality should be above 60. the reason of poor signal quality could be big interference,or worse installation of transducers,or using bad quality,not professional signal cable.normaly ,to adjust transducers repeatly,check the couplant that is enough or not,until the signal is better.

§4.8.3 Total transit time,delta time

The total transit times (or traveling time) and delta time are displayed on menu window M93,they can display whether the installation is suitable or not, They are the basic two parameters for the flow meter’s internal measurement and calculation,. When the data of delta time fluctuates too much,the showed flow rate and velocity will change quickly,under such condition,it means the signal quality is not good,perhaps the conditions of pipe is not good,not suitable installation of the transducers,or wrong parameters input.normaly the fluctuation of delta time is less than ±20％.but when the pipe diameter is too small or lower flow velocity,the fluctuation of delta time may be higher.

§4.8.4 Transit time ratio

Transit-time ratio (visit on M91)is usually used to check whether the transducer installation space is good .If the pipe parameters are correct and the transducers are installed properly, the transit time ratio should be in the range of 100±3

%.when the ratio is over the range,you should check, a) If the entered pipe parameters are correct?

b) If the actual space of the transducers is the same as or close to what shown on window

M25.

c) If the transducers are installed properly in the same axis plane of pipe?

28

TDS-100P MANUAL d) If the mounting location is good, if the pipe has changed shape, or if the pipe is too old (i.e., too much corrosion or liner inside the pipe)?

e) If there is any interference source around the flow meter?

§4.8.5 Note the following questions when installing

1，input pipe parameters must be correct,conform to actual facts,otherwise the flow meter will not work.

2,when installing clamp on type transducers,apply enough couplant to make the transducers attach on the pipe,check the signal streghth and signal quality displayed on the screen while moving the transducers around installation point to receive the best signal and signal quality.the

diameter of pipe is more wider,the range of moving transducers is more larger.then ensure whether the installation space is the same with that on M25,whether transducers are installed in the same axis line of pipe.if the signal streghth is 0.00,that means no receipt of ultrasonic beam,check whether the input parameters are correct or not, choosing installation method is correct or not,whether the pipe is too old,liner is too thick,is there fluid in pipe？the space is too near valves,angle head?too many air bubbles in fluid?if not these reasons,still no signal,so have to try another point,or use insertion type transducers.

3,ensure whether the flow meter work normaly:signal streghth is bigger,signal quality is higher,the displayed flow rate is more reliable,the meter can work for long time.if there is too bigger environment electromagnetic interference or lower receiving signal,then the flow rate displayed is poor,not be able to work normaly for long time.

4,after installation,enter M26 to solidify parameters,power on again,check results are correct or not.
