1 –TYPICAL APPLICATIONS:
The various versions of MiniSonic 600 & 2000 are essentially designed for high
performance flow testing in terms of quality and precision at a very competitive cost, in
particular if we take into consideration the reduced costs of installation. Through external
probes, there is no need for a measurement sleeve or for full pipe drilling to obtain final
precision comparable to that of a fixed station flowmeter, whatever the principle.
The design allows intelligent sharing of hardware and software resources to deal with the
problem raised. For instance, the two 4-20 mA current outputs can be assigned to other
values than flow rate (speed of sound, gain, etc.) to obtain full diagnosis incorporating the
quality of the fluid.
MiniSonic gives the volume flow rate and direction. Normally used as an instrument
assigned to a dedicated application, it can also be used as a temporary replacement for any
defective flowmeter or meter.
The external probe (SE) solution is possible with most fluids circulating through metal or
plastic pipes. Ultraflux offers a wide range of probes distributed in terms of frequency and
signs to suit a multitude of applications on inside pipe diameters ranging from 10 mm to
more than 3 meters. Accordingly, fields of use include petrochemicals and water, whatever
the quality, and with no limits on conductivity.
This probe supply is filled out by a supply of supports (SU) designed to assist with
installation and rigorous repositioning for maintenance purposes.
When the material of the pipe (concrete) or the conditions (corrosion, viscosity of fluid,
etc.) are unsuitable for external probes, we propose the installation of intrusive probes (SI)
on a sleeve, or by on-load tapping into the existing pipe.
MiniSonic is also capable of measuring gas flow rates under flow conditions. The external
probe method requires a number of conditions regarding the gas pressure and has limits
regarding the diameter of the pipes and their nature. The construction of a sleeve ensures
reliable measurements at low and high pressure, offering a wide dynamic measurement
spectrum from the lowest viscosities.
The instrument can be used for official metering. In this case, we recommend comparing
its performance with a standard hydraulic bench to obtain a calibration certificate. As long
as installation is correct, the instrument can be accepted as a meter. In this case, it is
advisable to construct a sleeve.
Generally, we use a “dry calibration” method or a calculation calibration method, which is
simpler and more economical and offer sufficient reliability for normal use.
In addition to its precision, MiniSonic offers very good ultrasound information
repetitiveness and high reproducibility. An installation defined under hydraulic conditions
that are not ideal or that are reproduced in a strictly identical manner will allow the setting of
a corrosion factor or a linearization curve so that the results can be maintained with
acceptable accuracy.
