1–TYPICAL APPLICATIONS
MiniSonic P and P-B main purpose is to offer a performing flow measurement solution at a
very competitive price by saving any installation costs.
With clamp-on transducers, there is no need of any spool piece or tapping by keeping the
same final accuracy than any flowmeter.
Their conception permits a smart use of the hardware and firmware resources to adapt
them end to user flow problem.
For instance the two 4-20 mA outputs can copy other data than the flow (sound speed,
gain …) to offer a complete diagnostic on actual flow and liquid quality or density …
The MiniSonic P gives the actual flow value and its direction.
Normally used as a portable instrument, it can also be use for temporary replacement of any
flowmeter: flow indication, regulation but also volume counter.
1-1 – Principle of measurement:
The principle of measurement is detailed and commented on in our training manual NT
106.
To summarize, note that it bears on the velocity difference (and therefore the ultrasound
wave transit times) in a moving medium, depending on whether the movement is with or
against the current.
To achieve this, it is necessary to establish dialogue between two sensors using an L-
shaped route whose projection D on the control axis is sufficient, and to measure
alternatively the route times T 1>2 and T 2>1.
The time measurement, combined with knowledge of the geometry parameters (diameter /
thickness of pipe / L / D) allows the volume flow rate to be calculated whatever the
developments of the product, its temperature or its pressure.
Precision is even better when the Delta T measurement resolution increases (0.01
nanosecond for MiniSonic) and when the geometrical parameters are controlled, not to
forget considerations of a hydraulic order (straight lengths, flow configurations, zero setting)
or the frequency of the probes.
An order of magnitude of this Delta T in nanoseconds can be obtained simply by multiplying
the flow velocity (V in m/s) times D (in mm) or by the diameter of the pipe (mm).

NT214B GB1 5 / 26
1-2 - The clamp on solution is available for most of the liquids flowing in metallic or plastic
pipes.
Ultraflux offers a very wide transducers range with different sizes and frequencies to be
selected depending on the application and pipe diameter from 10 mm I.D. to more than 3
metres.
This solution is very convenient for petrochemical products but also for any water quality
including demineralised water with no limitation from the conductivity.
When pipe wall material (concrete …) or condition ( corrosion …) is not suitable for clamp
on transducers , we propose insertion transducers with installation possibility by hot tapping.
When the instrument must have an official use, it is recommended to compare it to a
standard and obtain a calibration certificate on a flow rig.
Then, after some reserves concerning a correct use, the unit can be accepted as a
secondary standard.
Basically, we practice a dry calibration. It reliability is sufficient for a standard use.
Beside its accuracy, MiniSonic P offers a very good reproducibility.
If you place transducers at the same location and enter the same settings, you can follow
up in the time any pump characteristics or any other flowmeter actual accuracy.
Example with Direct mode:
Meanwhile, Reflex mode (V)
Is more usual ( > 90 % )
and much more easy l.

4 –USUAL CONNECTIONS ON MINISONIC-P or P-B :
When there is no need of automatic records, connections as described in § 3 are sufficient.
> To permit records and connection to an external data-logger or to a PC , or to any
recorder or transmission device , please use our cable and add if necessary
connections on 15 pins male connector . Its pin out is as follows:
> There are two categories of External data-logger:
•Those which are designed to receive 4–20 mA signals as the USB-4.
•They permit to set records rate and some permit to delay the acquisition or stop it at
a given time or other condition. Do wiring on analog output 1 (SA 1) or 2 (SA 2). Do
wiring of relay 1 or 2
Flow records are samples. There is no record about what could happen between.
•Those which are designed to record time events. If this event is the volume pulses
unit as transmitted by one of our relays, the time between two successive pulses
permits to build a curve representing the average flow during this period. These data
loggers are normally delivered with the corresponding Software.
Flow information rate depends on the flow itself. For instance a survey on a potable water
pipe will give few points during night and many at peek flow period.
Relays : solid state
R on = 10 Ohm
V < 100 V
I < 0.1 A
Analog outputs SA :

NT214B GB1 9 / 26
> Automatic records by using our Software on a desk top or lap top PC :
Please refer to our LS 600W x x Software manual (CD Rom)
- Once this software installed on your laptop PC you can set in its configuration menu a
sampling period and also the duration of the records. If you want to control manually this
duration, you must enter “ 0 “.
- When the RS dialog is established between this PC (master) and the MiniSonic-P or P-B,
the records start after a click on the Diskette icon and a given name to the new file.
- The main advantage of these records is their richness: you keep trace of all available
informations on MiniSonic. Totalizer can be automatically reset before a new record.
You can also record the corresponding calibration file.
- Moreover, our Software includes a Spreadsheet Macro for Excel, which permits an
automatic transfer and edition of your results to help your technical report.
Let you guide up to such a final result (example – not contractual):
Attention! To have this Macro accepted by Excel and Windows, you must set Excel security

6- PROBES INSTALLATION – General Procedures.
The MiniSonic P & P-B accept all standard or special transducers of Ultraflux
catalogue with frequency from 250 KHz up to 2 MHz : clamp-on , insertion or wetted …
®Unless specified and instructed otherwise in the order, refer to the probe data sheet
of the model used .
®The installation of the probes in a conduit should allow for the best the straight lengths,
particularly upstream, but also downstream, in order to benefit from a predictable and
stabilized hydraulic profile. Provide upstream a minimum of 15 times the pipe
diameter.
®Similarly, to avoid the nuisance of deposits or accumulation of gas, planes close to
vertical (+/- 30°) will be avoided. A horizontal plane is a good choice excepted when
the conduit is vertical.
®For intrusive probes, adjust the insertion then the alignment or orientation of the
probes for the same pair (> parallel faces).
Important! : once these adjustments finished , it is necessary to measure with
accuracy the distance L between transducers face to face and its projection D on flow
axis and note these values on a “as built ” data sheet for further entering in instrument
menu .
! The final accuracy depends on.
®For external probes, the freedom offered should not prompt the user to ignore
the above rules.
However, the choice of direct (\), reflex (V) or even (N or W) installation mode will
depend on the decision regarding the conduit (state) and the fluids to be measured.
Therefore, we advise initially a provisional installation known as a validation
installation (coupled with gel or grease) and final assembly (supports, solid coupling)
once the conditions have been validated.
Since the MiniSonic calculates for you the distance D.S required between the probes,
the setting up operations will, in theory, take place once the converter parameters
have been set.
Particular attention will be paid to cleaning the conduit at the probe location.

NT214B GB1 12 / 26
Probes installation : particular recommendations for a portable use :
Please read general recommendations as detailed in our training manual NT 122.
Under header § 2, we give some information about expected accuracy depending on
available straight length and transducers mounting modes.
When you will arrive in front a new pipe to be measured, you must have some good
reflex, and your experience will help for.
®First , you must have in hands suitable probes for the application .
We propose different sizes having each its own frequency: larger they are, lower is the
frequency.
- High frequency and small probes are suitable for small pipes, thin pipe wall and highest
accuracy in Delta T measurement. But signal could be distorted or damped if pipe or liquid
conditions are becoming difficult.
Example: our SE_1586-E2 – F=2 MHz
- Lower frequency transducers are less sensitive to above conditions and are more suitable
for large pipes. For such pipes, the Delta T is more important and thus weights less on the
results.
Example: our SE_1599-I or SE_1595 – F=0.5 MHz
- Between them, we offer a compromise with probes F = 1 MHz
Example: our SE_1662-A or SE_1596 or better SE_1515 which accept up to 200 °C
®Most of these above probes are delivered with a support which doesn’t let other
choice than to place them in Reflex mode. This Vmode must be preferred to all other mode
as far you can place the transducers (distance D.S. and signal = OK).
The probes coupling and its duration are very important for reliable results.
Try always to have a compromise for pipe access and straight lengths. All becomes
easier. When you have to do a measurement after a pump, please try as far as possible
from it. You will have fewer disturbances or remaining bubbles from cavitations.
®After installation finished and accepted, you shall be the first critic of the
measurements you are doing.
For this, MiniSonic delivers you complementary information on signal (Gain), on physical
measurement (Delta T, on sound speed (C – relation with T °C ?) and on hydraulics
(Reynolds number – Kh).
What to do with?
- A too high amplification gain would request to use lower frequency transducers.
- A low Delta T must be compared to the offset risk (Delta To). You have to decide about a
possible zero flow compensation.
- A sound speed very different from expected value would signify some mistake in pipe
data.
- A Reynolds number near the turbulent to laminar transition area would request the highest
attention to the probes location. Even if Reynolds number can predict a laminar flow, it is
necessary to have more than 20 x Diam. to establish it after a disturbance.

NT214B GB1 13 / 26
7- COMMISSIONING AND PARAMETERING OF MINISONIC P / P-B :
1. Once the cabling has been carried out and verified, power up the system:
> The MiniSonic must display its home screens:
- Hardware version = MiniSonic P or P-B and P.C. Board version (MK4_M).
- Firmware version = 18.10-01 (e.g. – make a note of the first figure)
- Serial number = see if it is identical to the company nameplate
- Technical information: parameterized probes
Then it automatically switches to the measurement function (Q = …)
> Check the consistency of these messages with respect to your application. If your
instrument is set ready to be used, you can start readings and records.
> However, it is recommended you to check and, if necessary, to optimize the
adjustments, taking into consideration the exact dimensions and, if possible, zero flow
conditions (see the “Self-zero Adjustment” menu).
2. Parameter settings using the PC software : Use same version than Firmware

The MiniSonic P-B can calculate a QTresult from Q1 & Q2 : sum , difference … Its
calculation formula must be entered by using our PC Software .
Concerning specific menus or displays available on LCD and Keypad , we can mention :
Measurement Display menu :
- Display of distance D.S. 1 & 2 for the two sets of probes (same reference)
- Display of calculated flow QTfrom entered formula
- Display of Gains 1 & 2 plus I.Q. 1 & 2 for the two pipes.
- Display of the two different flows Q1 & Q2 in the two pipes.
- Display of the two flow velocity and also the two sound speeds.
- Display of the two time of flight and the two Delta T on the two pipes.
- Display of the two hydraulic information’s Kh 1 & 2 and Reynolds number Rey 1 & 2
Calibration Allowed menu : identical to MiniSonic-P version
Pipe Settings menu :
- Entering for pipe 1 & 2 diameter and circumference: ext D 1 = xxxx.x / ext D 2 = xxxx.x
- Entering of pipe 1 & 2 materials: Pipe 1 = / Pipe 2 = …
- Entering of pipe 1 & 2 thickness: Thickness 1 = xx.x / Thickness 2 = xx.x (mm)
Q Settings menu : identical to MiniSonic-P version . These data are common to the two
pipes.
Probe / Echo Settings menu :
- Number of pipes / chords = 1 or 2
•If transducer choice is SE, mounting mode ( / , V , N , W ) must be the same for
the two pipes
•If choice is SM, it is possible to set separately the distances L 1 & 2 and D & & 2
- Management of amplification gains 1 & 2: Gain 1 = ESC … / Gain 2 = Auto …Manual
- Management of the two gains in Manual mode: Gain 2 = xx dB or
- Management of the two margins in Auto mode: Margin 2 = xx dB
General Settings menu : identical to MiniSonic-P menu but
- Possibility to copy QT or Q1 or Q2 as a 4 – 20 mA output
- Possibility to set Tot 1 or Tot 2 on flows Q& or Q2 or QT
Zero / Auto-Zero Settings menu:
- Possibility to do the Auto-Zero separately on pipes 1 & 2
- Possibility to set or reset separately Delta To 1 & 2
Ouuput current Settings , Factory settings and I/O Test menus: as MiniSonic-P
Echo Display menu: it put multiplexing off for signal controls with oscilloscope.
