5 Page 5 of INTRODUCTION Thanks for buying an Ultrasonic Transit Time Flowmeter TTFM100-NG series. The device measures flowrate by calculating the spreading time of an ultrasonic wave in a liquid, going upstream and downstream into a pipe. This flowmeter is mostly used to measured the flowrate of homogeneous fluids, with a very little percentage of suspended solids and possibly without gas bubbles. Its peculiar installation makes this devices suitable for measuring aggressive fluids (acids, basic and dissolvents) or very soiling fluids(oil and fuels). The measuring system is composed of a couple of ultrasonic transducers acoustically coupled to the external pipe s wall (it is also possible to use transducers in direct contact with fluid to be measured) and a HOST unit elaborating the sent and received signals from the transducers. The HOST unit has a DSP microprocessor, it gives signals to interfacing with the process or the control systems. The devices main features are: Clamp-on sensors: it is not necessary to stop the flow to install them. AC and DC supply: 230 VAC. The time difference during the measuring process could be 0.2 ns. RS232 output. All the measures could be driven to the RS232 in order to save data into a PC or a serial printer.

6 Page 6 of 1. WORKING PRINCIPLE When the ultrasonic wave spreads in a liquid, the flow will cause a changing in the spreading time depending on downstream or upstream current. The ultrasonic wave going towards the same directions of the flow increases the spreading speed, while the ultrasonic wave going towards the opposite side of the flow decreases the spreading speed. If the difference between the two spreading times is accurately measured, it would be possible to calculate the flow speed (see the following picture). The measures are taken by 2 sensors in direct contact with the pipe s external surface. The UP sensor (RED) is placed on the upper side of the pipe s external surface, the DOWN sensor (BLUE) is placed on the lower side of the pipe s external surface. The sensors positions could look like a Z or like a V or a W, if the pipe has a small diameter (in the previous sketch, the sensors are Z mounted). The sensors are alternatively used to receive the ultrasonic pulses sent through the way pipe - fluid - pipe. The difference between the transmitted and received signals upstream and downstream is calculated as follows: (1) (2) (3) M D Tup COS Co VSIN M D Tdown COS Co VSIN M D T V * * SIN 2 Tup * Tdown

7 Page 7 of Where: M Spreading time D Pipe s internal diameter Ө Transmission angle Co Sound spread speed through the fluid in static conditions Tup Positive spreading time Tdown Negative spreading time V Flow Velocity The DT value is the difference of the spreading time into a homogenous fluid without gas bubbles. The equation (3) for calculating the average speed V could be used for all the types of fluids in ideal conditions. The fluid speed measuring is in fact conditioned by different factors which make the precision decrease: for example the dumps on the pipe are internal walls: they change the measuring principle of the transit time flow meter. TTFM100 series has are a lot of solutions trying to solve these problems, compensating the temperature influence, the dumped internal walls and the asymmetry in the speed distribution, in order to measure in critical conditions too. It is possible to adjust the zero point of the device: if the fluid is in static conditions, this operation makes the repeatability precision increase until reaching values near to 0.5%. 1.1 TYPICAL USE Water treatment, slurry and process water pumping; Oil and chemical industries; Hydro-electric, cooling, anti-fire stations; Extraction industries; Food, paper and pharmaceutical industries; Car industries; Flow balancing; Heat measuring in central systems.

10 Page 10 of 2. INSTALLATION AND OPERATION The installation of TTFM-100-B-HH-NG series is quite simple. It is only necessary to determine the mounting point in the pipe and knowing some information about the pipe s dimension. 2.1 MEASURING POINT It is very important to select the right measuring point. The fluid has to be a measurable fluid and the pipe should be suitable for this measuring technology. Do not hesitate to contact B.M. TECNOLOGIE INDUSTRIALI for any further clarification. Please proceed as follows: 1) Select the measuring point on the pipe, in order to have a fluid free from turbulences. 2) The distance of measurement point upstream is 10D, downstream is within 5D. If there is valve upstream, it is suggested to increase the distance up to 30 D. 3) Actually, the device could be installed into pipes with lining, but it is suggested to avoid it above all if the pipe is old or damaged. Pipes should be suitable to this measuring technology in order to improve measure and precision.

25 Page 25 of 2.5 TRANSDUCER MOUNTING METHODS The transducers mounting positions are related to the pipe diameter and to the type of sensors. V and Z methods are the most common. By the way, V mounting is suggested. The other mounting methods are N and W. The letters V, Z, N, W stands for the number of signal crossings from one transducer to another. Z= one crossing. Suitable for pipes > DN250 mm or smaller. V= two crossings. It is the easiest mounting method for DN pipes with TL-1 or TM-1 transducers. N= three crossings. Suitable for small pipes, DN100 or smaller, with TS-2 transducers. It similar to Z method, but for small pipes. In this case, the mounting distance will be bigger. W= four crossings. Suitable for DN20 pipes with TS-2 transducers. It similar to V method, but for small pipes. In this case, the mounting distance will be bigger. The following example shows the different mounting solutions. Z mounting method V mounting method N mounting method

26 Page 26 of W mounting method W mounting method V mounting method is the most common. It can be applied to almost all the applications: it is the most simple and rapid one. Z mounting method is suggested only if the signal strength, UP and DOWN (DN) is smaller than 60 and Q value is smaller than 60, see MENU 90.

27 Page 27 of S trenth+quality [ 9 0 U P : D N : Q = V mounting method The V method the bounce of the ultrasonic signal inside the pipe. This increases the distance crosses by the ultrasonic wave. The measuring principle is based on the time difference and through a V distance, the time needed is bigger and the precision higher. In case of horizontal mounting, it is suggested to avoid the sensors mounting on the top or on the bottom of the pipe. Air bubbles on the top of the pipe could stop the ultrasonic wave and deposits on the bottom decrease and change the ultrasonic beam angle. Refer to the picture below. In case of vertical mounting, avoid installing the transducers on downward pipe walls, even if they are under pressure. The pipes with an external liner such as tar, polyethylene, epoxy, should be cleaned when in contact with the transducers. A tube for acoustic coupling gel for sensors installation, is included in the supply.

28 Page 28 of Use a small quantity of coupling grease in order to improve acoustic the contact between the sensor and the pipe s external surface Z mounting method Press 1 while in menu 24, if you want to choose Z mounting. M 2 4 T r a n s d u c e r M o u n t i n g 0. V - M e t h o d => 1. Z - M e t h o d Press and the device will display: M 2 5 T r a n s d u c e r S p a c i n g m m Z mounting method is more complicated than V mounting method: it is necessary to create a band of foil as long as the pipe circumference and as wide as indicated in MENU 25. Additionally, add a piece of paper to wrap the pipe. Please refer to the picture below for finding the two lines needed to trace the exact half point of the pipe.

29 Page 29 of Once the fascia is fixed on the pipe s circumference (with adhesive tape), it is possible to fix the sensors, as shown in the picture. If the pipe is horizontally mounted, it is suggested to mount the sensors as shown in the next picture. If the pipe is vertically mounted, refer to the instructions of V mounting method.

30 Page 30 of W & N Mounting Methods These methods are suitable for small pipes, DN100 or less, with TS-2 transducers. The signal path consists of four crossings (for W method) and three crossings (for N method) inside the pipe. These methods are used to increase the transit time and receiving time, otherwise the signal path in small pipes will be too short. In W method, the sensors are placed on the same side of the pipe at a definite distance, in N method; they are placed on the opposite sides of the pipe, at a definite distance. These methods are not very used because small sensors TS-2 could be installed by using Z method. To choose N method, press 2 while in menu 24. M 2 4 Tra n s d u c e r M o u n t i n g 0.

In normal working conditions, the signal strength should be higher than The signal quality (Q) is displayed by numbers from 00.0 to means the signal is the worst mean signal is the best. In normal working conditions, the signal quality should be higher than During installation, please pay attention to signal strength and quality: they should be at the maximum level.

32 Page 32 of Total spreading time, time difference M93 MENU 9 3 T o tal T ime T im e, D e lta 6 23,80uS, 2 42,12nS The measurement method is based on time difference, so the time and other displayed values can identify a correct installation. In normal operating conditions, the time difference should be smaller that ten percent (10%). If the pipe diameter is small or the speed is too low, the difference may be a little higher. If the difference (and also flow and speed) is too high, it means the signal quality is very bad. The reason may be: pipe s features, wrong installation or wrong parameters setting Relation between calculated and measured transit time To know if the sensors are well mounted, you should calcolate: TIME RATE = TOM * 100 TOS In normal working conditions it should be 100 +/- 3%. T O M / T O S * x x x, x x % And eventually confirm the right mounting method.

Please be informed that a Laptop PC with Windows XP Operating System. 1. Required Hardware For information about the serial port and the connection cable, please refer to Chapter 5 of TTFM100 instruction manual. Note: Your PC has normally more than one USB ports so you need a converter for the serial connection to TTFM100 series instrument. If you use the wall mounted version, you need a RS485 to USB converter. If you use the portable version, you need a RS232 to USB converter During the set-up and the data logging, the port number the system gives to the added USB serial converter is required; please check it in Device Manager Window. In the picture the Comm. Port number is Initial settings for Data Logger Function Please Ref. to Chapter for a general description of Data Logger function. In the following example, only a few measures, available on the serial port RS485-RS232, are set as ON. Other measures COULD NOT BE. It is supposed the PC is ready to work. Normally with the operating system, there is a program to perform serial communications between various devices and a PC. In this case we use a direct connection (without any modem) and the following example is based on RS232 Data Logger. The latest can be downloaded for free form the Internet.

101 Page 101 of 2.2 Hardware connections between TTFM100 & PC For stationary units, connect the device serial cable to the serial port RS485 and to the PC. You need a RS485 or RS232 converter to USB, depending from the laptop you are using. Serial converter RS485 to USB

102 Page 102 of For hand held units, connect the devices serial cable to the serial port RS232 and to the PC. In this particular case we used an RS232/USB converter. It was connected with a short cable to a PC s USB port.

103 Page 103 of 2.3 Connection software between PC & TTFM100 series The most important function needed in a serial connection management program is the possibility of acquiring data from a serial connection. There are many programs able to do this but we suggest to use a free program from It can be supplied along with the manuals and it is completely free. After its installation the main window looks like this. With this button you can set the name_file StartLoggin / StopLogging button. You must set the same parameter as in MENU 6 2 the of the wall mounting or hand held unit. Choose the AVAILABLE port!

104 Page 104 of Before StartLogging go to M52 menu window and choose Buffer to RS232 selection M 5 2 D a t a D i r e c t i o n 1. T o B u f f e r = > B u f f e r > R S Click on StartLogging and than on ENT button on TTFM100. You could see immediately the bytes received counter increasing. If you have thick the box the data will be appended to the same filename. The total bytes in the file will be the result of adding one or more files. When the download is complete, press the button. Now the saved file will be saved in the defined directory:

How to use Excel to read the.txt data The following paragraph will only give a general information about how to manage the data logged with the previous indicated functions. 3.1 How to import.txt files in Excel The user who wants to use this option must have a minimum Excel knowledge: all the procedures for opening and searching for files in the PC directories must be known. Start the program and open a logged file (this file should have been logged during a regular TTFM100 functioning). The following example uses a file called TEST_CAPTURED_FILE.TXT. In the last example we used My Documents folder to store the captured file. Attention: in order to display that file, please select All files (*.*).

106 Page 106 of The following Text Import Wizard window will appear: Choose Windows (ANSI) Click on Next> and it will display:

108 Page 108 of It is possible to change the columns width in order to display the date correctly. For example: Click with the mouse right key on Column A and then click on Column Width and set it to 12. It is necessary to re-elaborate the data because of the disposition in columns and lines. In fact it does not permit to create a reliable bar graph of the desired measures. The menu called Data helps the user to extract data, for example: the flow rate is the temporary date hour: minute: sec (h: m: s).

109 Page 109 of 3.2 An example of Flow Rate Bar graph Select the first 3 columns A-B-C and click on Automatic Filter as follows: 3 tags will appear on the upper right corner of each column: Click on the first tag and select the acquisition date line (it is assumed that the day is the same for all the columns!!).

110 Page 110 of Excel will now extract the data into the lines according to the searching criteria. The date referes to the hour in which the flow rate was logged. During the text file import, Excel generated only one sheet in the folder, but at least another sheet is needed in order to manage this data extraction.

111 Page 111 of Click on Insert, click on Worksheet and a new sheet will appear, named Sheet 1. Return to the original sheet. Select the data into the hour column, and copy them. Go to sheet 1 and paste the copied data.

112 Page 112 of Now the acquisition time data are ok, but the flow data are still missing. Go back to the original sheet and click on the first tag, selecting Flow.

113 Page 113 of Now the B column will display the flow data. The C column will display the flow rate engineering units. Select and copy the flow data, as done for the time data, and paste them in Sheet 1

114 Page 114 of Now the data for the X axe and Y axe of the graph are complete. Select the 2 group of data: Go to Insert, Chart Now the type of Chart should be selected. Go into the Chart Wizard selection table and choose, for example, XY (Scatter) and then click on Next button.

115 Page 115 of The following window will be displayed: It is possible to see the type of chart displaying the time flow rate. Click on Next button.

116 Page 116 of It is possible to scroll all the display options or go directly to the 4th screen. Click on Next>. The last window will be displayed: It is suggested to create the chart into a new sheet, Chart1 in the example windows. Then Click on Finish.
