We offer a full range of portable or fixed flowmeters backed by 30 years’ expertise and
experience using Ultrasonic techniques:
®The Digisonic and UF 801-P families of Portable flowmeters with integral
loggers and signal analysis functions
®The UF322 and UF 8xx families of fixed installation flowmeters:
L - liquids,
G - Gas ,
MC – Multi-chord applications for Liquid and Gas measurement,
CO / RV - Open Channel and River Measurement.
®The MiniSonic family with :
P – Portable Metering with also a two pipe or dual path version P-B
600/2000 single-channel fixed flowmeters,
600-2 and 2000-2 for dual-chord flow metering ,
600-B and 2000-B for dual-pipe flow measurement configurations,
Speed ( 1 or 2 ) is for open channel flow velocity measurements.
This manual is specifically concerned with an element from the family and has been
drafted to guide you in the stages of installation and commissioning.
Other documents and tools are available on paper or in electronic format:
•A training manual concerning ultrasound measurement, reference NT 122
•A guide about the use of our software in the Windows environment Ref NT 204
•The PC software that is specific to your application, Ref LS 600W _version *** ,
with an interconnection cord to the PC.
•The JBUS communication protocol with its address table NT 207
All our flowmeters work on the principle of transit time of ultrasonic waves and can be
associated with clamp-on or wetted probes as well, depending on the application.

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.

> 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
level at medium or low (Excel/Tools/Security…)
