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.

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:

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%.

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.

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 DN600-800 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.

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”.

2.5.1 “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.

2.5.3 “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.

2.5.4 Mounting Analysis

After checking the strength of the received signal, the total spreading time, the time

difference and the rate of spreading time, it is possible to confirm if the installation is

correct.

2.5.5 Signal strength and quality M90

Digit

The strength of signals is displayed by numbers from 00.0 to 99.9.

00.0 means no signal received, 99.9 means max signal. In normal working conditions, the

signal strength should be higher than 60.0.

The signal quality (Q) is displayed by numbers from 00.0 to 99.9. 00.0 means the signal is

the worst. 99.9 mean signal is the best. In normal working conditions, the signal quality

should be higher than 60.0.

During installation, please pay attention to signal strength and quality: they should be at

the maximum level.

2.5.6 Total spreading time, time difference M93

Digit

Tota l T ime,De l ta T ime

623 ,80uS, 242 ,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.

2.5.7 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%.

The continuous displaying of errors helps the customer identifying damages or unacceptable working conditions. Displayed errors could happened:

- When switching on the device, during the initial test. - During functioning, with error codes.

Causes and solutions are indicated in the below following table: 4.1 AUTOTEST DURING SWITCHING ON AND POSSIBLE SOLUTIONS

ERROR DESCRIPTION

SOLUTIONS

ROM PARITY ERROR Contact B.M. Tecnologie Industriali.

STORED DATA ERROR

Digit ENT again during the initial set up.

TIMER SLOW ERROR TIMER FAST ERROR

Switch off and then switch on. If the problem persists, contact B.M. Tecnologie Industriali.

DATE TIME ERROR Set again date and time in menu M61.

4.2 ERROR CODES, CAUSES AND SOLUTIONS DURING FUNCTIONING ERROR CODE

INFORMATION IN M08 WINDOW

CAUSES SOLUTIONS

*R Normal system Regular functioning

*J Sub CPU wrong Damage in sub CPU Contact B.M. Tecnologie Industriali.

*I No signal detected No signal detected: - sensor far fro the

pipe or not so couplant

- wrong sensors mounting

- too many oxide or dump inside the pipe

- new linearity

- check the acoustic contact with the pipe’s surface. - use another couplant - check initial settings - try to reduce the pipe’s internal dumps or change the sensors position - wait for stable linearity.

*F System RAM error Date Time error CPU or IRQ error ROM parity error

Temporary RAM or RTC problem. Permanent Hardware problems.

Switch off and then switch on or contact B.M. Tecnologie Industriali.

*K Empty Pipe Wrong settings in M29 Replace the sensors where the pipe is full. Set “0” in M29.

4.3 OTHER PROBLEMS AND SOLUTIONS

a. If the flow is not static and the device displays a flow rate of 0.0000, the code “R”, and signal strength and quality are satisfying, the problem could have been caused by the user who set a high “zero” value. Solution: reset the device using M42 function. It will restore the factory settings.

b. The device displays a flow rate which is much higher or much lower than what

usually displayed in normal working conditions. - Probably there is a problem with the OFFSET value. Set “0” in M44. - Wrong transducers mounting. - Reset the device by using M41 function. Check that the flow is completely

static.

c. The battery works for a short period. Shorter than what stated in M07. - Replace the battery: it is over. - Contact B.M. Tecnologie Industriali.

5.4 USE OF THE PREFIX IN THE CONTROL

a. PREFIX P: The P prefix is added before starting a control indicated in the above mentioned list, in order to obtain a 2 byte control on the CRC code.

Example: control DI+ (CR). The device replies with a value of +1234567E+m3(CR)(LF), the converted hexadecimal line is 2BH, 31H, 32H, 33H, 34H, 35H, 36H, 37H, 45H, 2BH, 30H, 6DH, 33H, 20H, ODH, 0AH. The same control with prefix P will be PDI+(CR), the device will reply giving a value of +1234567E+m3!F7(CR)(LF). “!” acts as a control start for summing the line values, 2BH, 31H, 32H, 33H, 34H, 35H, 36H, 37H, 45H, 2BH, 30H, 6DH, 33H, 20H. Before “!” there will be som free spaces (20H).

PREFIX W: it is used to control a net of devices for addressing the control’s receiver device. Synthax composed of: IDN + base control. It is possibile to use various ID between 0 and 65534, but 13 (0DH), 10 (0AH), 42 (2AH,*),38 (26H,&).

Example: if IDN is 12345 and you want to calcolate the speed value of the addressed device, the control to be used will be W12345DV(CR).

b. PREFIX N: it not used anymore in the new versions of TTFM100B.

c. CONNECTION CONTROL &: the & control permits to establish a connection up to 6 simple controls in order to speed up a devices questionnaire.

Example: we are asking to a device connected to a net with IDN=1234, the following information: Flow rate, Speed and POs Totalizer. The control will be: W1234DQD&DV&DI+(CR), the reply will be +1.234567E+12m3/d(CR) +3.123456E+00m/s(CR) +1234567E+0m3(CR)
