Vision
Monitoring water is becoming more and more important. Resources, particularly drinking water are extremely limited. In areas requiring irrigation, especially in very dry districts, man is already fighting to make good use of the last drop.
Without doubt, the acoustic discharge measurement has enhanced its prestige. It is used as a fundamental information for water management in the field of hydrology, for the control of processes in the field of hydro power as well as for water supply, industry and waste water applications.
The acoustic principle has become a growth driver for flow meters. More and more users have already begun to appreciate the advantages of contact free measurements. With a comprehen-sive range of products and solutions we can determine flow in various applica-tions. Accuracy and reliability are given top priority. HydroVision products owe their quality to rigorous testing under laboratory conditions and their con- tinuous development. We are not
satisfied until our instruments meet the required accuracy under real field conditions.
HydroVision’s broad knowledge in the area of acoustic flow measurement is reflected in our product range for stan-dard applications. It becomes even more apparent when complex tasks have to be solved.
HydroVision is committed in equal mea-sure to consulting, delivery quality, service and support.
Water is a valuable commodity, with which we feel connected in a special way. HydroVision is passionate about its products and can look back on many years of experience. HydroVision starts where others stop. We are continually developing our product range to stay one step ahead. This enables us to reliably solve all your measuring tasks.

In this product overview we describe the various applications for our instruments. A vast amount of applications can be solved using acoustic flow measurement. HydroVision is at the forefront of “State of the Art” and future development.
Our measurement instruments can be used everywhere where there is flowing water. For example rivers, channels or pipes – we measure everywhere.

When sound propagates through water, pressure fluctuations can be detected. They travel through the water, the channel or the pipe as sound waves.With our instruments it is possible to record these ultrasound waves.
Depending on the measurement technique applied, we detect the Transit Time with and against the flow direction. For other applications we use the Pulse Doppler effect. Here our instruments record the change of the wave length reflected by a particle in the flow.

Rivers
Numerous rivers intersect our landscape from small brooks up to huge river networks. Some of them form a natural border between two countries.
At all times man has preferred to live in river areas. Clear water, the possibility to use the river for trans-port, generating power from water and the scenic beauty are amongst the reasons. However, our actions have more and more influence on water quantity and quality. In many regions taking water for irrigation or as drinking water are the reasons. More than half of all big rivers around the world have been polluted during the course of time.
Observations of water levels have been used since ancient times, systematic flow measurements go back to the middle of the 19th century. This historical data has been used as the basis for various applications, for example for flood protection and flood forecasting. They also form the foundation for the design of hydro-engineering constructions. In recent years the acoustic flow measurement has established itself as the standard method for measurements on many hydrological stations. With this almost contact free technology data can be recorded continuously and it provides 24/7 monitoring.

Transducers
ProductsThe range of application for Fluvius TT runs from small waterways to huge river systems with high suspended solids. By means of acoustic transmission a coded signal is sent through the water and the transit time is calculated providing the speed of river flow. When an acoustic wave propagates in water, part of the energy is damped by friction and suspended solids. This procedure is frequency-related. The higher the frequency, the bigger the damping. For wider distances we use low frequencies as they allow for a considerably better receiver signal.

Channels
Channels are artificially created waterways used for shipping, transportation, irrigation, drainage and for cooling water extraction of power plants.
A further important use is the transportation of water used for the supply of drinking water. Here the focus lies on detecting water loss at an early stage; some- times it is difficult to detect small leakages.
Our instruments measure precisely and reliably in order to prevent long term water losses.

Mounting AssemblyStandardized mounting devices are available for any kind of channel geometry like rectangular, trapezoid or natural river banks. The flow optimized design protects the transducers against moving objects suspending in the flow stream. It also provides room for connections and protective conduits.
Transducers
TD-200/8
In its most basic form, the system operates with a single pair of transducers.
However, it relies upon a relatively stable velocity profile, essentially unaffected by changes in the rela-tion between water level and flow.
The main flow has to be paral-lel to the bank. The relationship between measured velocity and
flow is established by hydrometric
calibration.
In rivers there is a high risk of cross flow. Its intensity depends mainly on the river’s geometry and if there is an upstream bend in the river.
Although the cross flow does not influence the quantity of the flow, it may affect the measure-ment, a second pair of trans- ducers will be necessary.
By crosswise arrangement of four transducers, effects of changing flow direction can be eliminated.
An even more accurate flow mea-surement can be obtained with systems using several planes.
The measured result can be further improved by using a multi path system layering each of the acoustic paths in parallel planes one above the other. This negates having an expensive hydrometric calibration. This type of system is suitable for applications with large water level fluctuations, reverse flow or a ver-tical velocity distribution outside the theoretical normal.

Hydro Power
Hydro power is an important source of energy which contributes to supplying power to the earth’s popula- tion. Today, hydro power plants deliver approximately 3,5 per cent of electric energy generated worldwide. Their share in power generation from renewable re-sources comes to 18 per cent. In the future this share will continue to grow, as resources of fossil fuels are depleted.
The hydro electric performance depends essentially on the usable altitude difference between upper reservoir and lower reservoir, and hence the flow. In order to use the “fuel” water in an optimal way, this flow has to be monitored without any interruptions.

Ductus TT ECM IETravel time system with digital signal processing
For pipes with a diameter of more than half a meter, acoustic flow measurement systems have long established themselves as a reliable and convenient measurement method. Measurements in several planes are a recommended method to determine the efficiency of the turbine without the need for calibration meeting the latest international standards. Fixed installed equipment form the basis for verifying the efficiency. A deterioration of efficiency can be detected right away and therefore corrections can be initiated at an early stage.

Water Supply
Although there is enough water on earth and it is not consumed but merely used, drinking water starts to get short. The uneven distribution of water amongst the regions, the rising population and our carelessness leads to a shortage of fresh drinking water.
In the future more and more pipelines for drinking water will be built all over the globe. In order to operate huge and complex pipe networks efficiently, flow measurement will be necessary.

Concept Innovation
Space constraints and/or appropriate application configurations lead to complex industrial pipe flows which
contain elbows, tees and/or other disturbing and non-uniform elements. This leads to difficulties in install-
ing flow meters at a recommended “optimum” location, which is defined by a minimum distance upstream
or downstream of known disturbances like an elbow or pump where a fully developed velocity profile is
present. Even with multiple flow sensors, there may still be a significant error which is known as the profile
factor.
flow meter after a 90° elbow
Prior knowledge of the profile factor can be used to correct the velocity measurements made by flow sensors
to a true spatially averaged velocity. The ReVision® acoustic system provides detailed information on the
flow velocity profile and an accurate measurement of the flow rate can be achieved by rebuilding the whole
flow velocity profile across the pipe using predetermined conduit configuration parameters and correction
factors. Flow meters are also sensitive to velocity profiles where there is a large rotational component (swirl).
Flow meters are also sensitive to velocity profiles where there is a large rotational component (swirl).
Swirl is normally generated by two
or more out of plane changes in flow
direction (e.g. one elbow/tee that goes
from vertical to horizontal followed by
an elbow/tee that changes the direction
of flow in the horizontal plane). Swirl is
present to some extent in almost every
application and can generate significant
transverse velocity components plus it
takes a long distance to dissipate. If the
swirl is not centred, it can cause significant
errors. Thanks to the predetermined con-
duit configuration parameters and correc-
tion factors, the flow meter measurement
accuracy is kept when asymmetric profiles
and swirls are present in the pipe. 15

Waste Water
Drinking water is not the only area requiring flow measurement. The disposal and cleaning of waste water is of equal importance. Waste water contains a multitude of organic sub-stances which used to be dumped directly into the soil or the nearest river. As awareness has increased, most discharges are now treated to assure long term sustainability. The contamination of surface waters has now been reduced and the oxygen content could be increased once again. Due to the advance of waste water treatment around the world nature was able to regenerate in many places. Today’s civilization is un-thinkable without functioning water treatment plants. Modern plants are highly complex systems.
They consist of channels for waste water flow, facilities for waste water collection and clarification plants. HydroVision can complete flow measurements in all of these areas.

ProductsFor sewage-treatment plants flow measurements are primarily installed for internal reasons, for example to control specific plant components with flow dependency or for controlling additives. International regulations, for example the EU-Directive for handling municipal waste water, require a continuous surveillance of waste water flow. Defective flow measurements on sewage-treatment plants can therefore influence their operation, but there can also be legal or environmental consequences.

Q-Eye Radar MT is an extremely versatile flow mea-
surement system designed for continuous operation
and suitable for measurements of flows not only in
rivers and open channels, but also in municipal waste-
water and storm water sewers. Compact construction
combined with the contact-free measurement princi-
ple enables an easy installation and use. The maximum
permissible installation height above the surface is 30
m. For waste water applications we suggest 10 m.
The ultrasonic depth sensor operates by energizing a
piezoelectric transducer with an electronic pulse. This
pulse creates a pressure wave that travels to the flow
surface where a portion returns to the transducer. Our
transmitter offers the best in liquid measurement. It is
easy to install, eliminates maintenance caused by sen-
sor fouling and your personnel do not get in contact
with the fluid during installation.

It uses advanced Doppler technology to establish the velocity in many separate space points (cells) along the measurement axis and develop the flow profile.

Permanently installed applicationsThe AquaProfiler® MT is a profiling instrument designed for permanent installations. With the 2-dimensional velocity sensor and a resolution of max. 64 cells, the system is the best choice for flows affected by variable backwater, sluggish, slow moving flows, ice-affected flows, tidal flows and flows where flow reversals may occur. Combined with an integral pressure sensor for determining the depth, the meter is using a numerical model for averaged velocity in the entire cross section and the continuity equation to calculate flow. Alternatively, the index-velocity method can be used, as the sensor gives an index velocity for a signifi-cant part of the flow which can easily be related to the mean velocity of the cross section.

The AquaProfiler® M-Pro is an instrument that oper-ates in a manner very similar to an Acoustic Doppler Current Profiler (ADCP). The primary difference is that the probe is kept fixed on the channel bottom and provides vertical velocity data in up to 128 cells. Due to the very small cell size (0,005 m), a resolution of the vertical velocity distribution can be achieved which was unthinkable a few years ago. The AquaProfiler® M-Pro is a device that extends the capability of flow measurements to a range of situations under which standard current meter techniques (mechanical or electromagnetic) cannot be used.
The AquaProfiler® M is a high-precision point-
velocity meter. It uses a complex pulse-to-pulse co-
herent sampling scheme that gives the instrument
high precision in measurement of velocity within a
very small volume a few centimeters in front of the
sensor. The small sampling volume provides velocity
data that can be considered as point velocities.
The advantages over mechanical meters include:
no moving parts, thus less maintenance required,
minimal flow disturbance, velocity measurements
as low as 0,005 m/s and minimum operating depth
of 2 cm (0.78”).
