INTRODUCTION
1 INTRODUCTION
1.1 Applications
The Thermo Scientific Sarasota 2000 is a velocity x area open channel flowmeter which uses
the ultrasonic “time of flight”, also known as the “transit time” method.
Unlike traditional methods of open channel flow measurement which use weirs or flumes, the
transit time method creates no obstruction and assumes no relation between level and flow. It
will correctly determine flow throughout its designed range by measuring water velocity and
cross section area (see Section 1.2).
The method is tolerant of backwater effects caused by tides, downstream confluence or
blockages. Unlike a weir or flume it does not drown out at high flow conditions.
The method employs the transmission of ultrasonic “beams” which can be affected by factors
which impede or deflect them. For this reason the method should not be used in situations of:
• Aerated water
• Weed growth between the transducers (unless it is regularly cut)
• High levels of suspended solids (greater than 2000 mg/l) *
• Gradients
• Gradients
* In relatively small channels (up to 5 metres) the method is more tolerant of suspended solids
and therefore is often used in sewage applications.
Though described as an open channel method, the flowmeter may be used in closed
conduits, including those which run full. In the latter case, the cross section area is defined by
the conduit geometry without the need to measure water level.
Suitable applications include water flow measurement of:
• Rivers
• Canals
• Aqueducts
• Irrigation conduits
• Sewage discharges
• Sewage works
• Industrial discharges
• Power generation
Note that although the flowmeter is most often used for open channels or part filled conduits,
it is often used for conduits which always run full. Under these circumstances it is not
necessary to have a depth input but steps need to be taken to ensure that the flowmeter
always takes the conduit as full. This is done via the encoder depth input. The conduit shape
must still be entered.

1.2 Principle of operation
1.2.1 The Standard
The Sarasota USMP is a velocity x area open channel flowmeter which uses the ultrasonic
“time of flight” method. This is also known as the “transit time” method. It complies with the
International Standard ISO 6416. The UK version BS 3680 part 3E is identical. The transit
time method belongs to the general category of velocity x area methods. A full description of
the method and its applications is to be found in the Standard. A brief summary is given
below.
1.2.2 Velocity x area method
Velocity x area methods require a means of determining the water velocity and the cross
section area. The product of the two produces the flow rate in a manner which is not
dependent on factors influencing the level, for example downstream constrictions, tidally
influenced wat er level et c.
Assuming the shape of the channel cross section is stable, determination of the area
becomes a matter of measuring water level. This may be done by a variety of methods.
1.2.3 Water level
Water level is required in order to determine the cross section area in an open channel.
Though a single level measurement may be used, it is common to use more than one and to
average them. This has the advantage of a more representative level, particularly if the
measurements are made at different positions, for example on either side of the channel.
Another advantage is that flow may still be computed even if a level sensor fails.
Level may be determined by using one or more ultrasonic transducers in the water facing
upwards. The time taken for a pulse of sound to return to the transducer after being reflected
from the surface is converted into level using the velocity of sound in water as measured on
the water velocity paths (see Section 1.2.4). There is a minimum depth of water required
above the transducer for it to carry out a measurement. This is given in Appendix 3:
Specification.
Water level may also be provided by external auxiliary depth gauges, for example pressure
transmitters, downward facing ultrasonic devices and float systems with shaft encoders.
1.2.4 Water velocity
In the transit time method, water velocity is determined at a number of heights within the body
of water by measurement of time taken for pulses of ultrasound to travel across the channel
at an angle to the flow direction.
Transducers are mounted in the water at or near the sides of the channel with each pair
usually at the same height and aligned so as each one can transmit a “beam” of ultrasound
towards its partner. The ultrasonic “path” between the transducer pairs must be at an angle
(usually about 45
Each transducer acts as a transmitter and receiver and is connected to a processing unit,
which measures the transit time and the time difference.

Flowmeter
The mean water velocity at the height of each path is determined from these timing
measurements, based on pre-determined geometrical measurements (length of the path and
the angle to the flow direction).

It may be shown that the water velocity at the height of the path AB is:
v = L x (T
– TBA) / (TAB x TBA x 2 cosθ)

Where
T
T
= Transit time from transducer A to B
AB
= Transit time from transducer B to A
BA
L = Path length (distance between transducer A and transducer B)
θ = the angle between the “path” and the direction of flow.
1.2.5 Flow determination
The flow is determined by combining the water velocity measurements at the height of each
path with the cross section area defined by the water level and the shape of the channel. The
channel shape need not be the same as the projected width between the transducers. For
example if the transducers are mounted on piles inset from the channel sides. For the
purposes of flow determination the cross section area is divided into horizontal slices
determined by the channel bed, the heights of the paths themselves and the water surface
level.
The channel flow is the sum of the flows in each slice determined by the path velocity or
velocities and the area of the slice. The bottom slice is defined by the bed (which is assumed
not to move) and the top slice by the water level (which is measured). The slice widths may
be determined by the projected width between the transducers or by a separate table defining
the cross section shape.
There are 2 methods, mid section and mean section.

1.2.5.1 Mid section method
In the mid section method, the slice boundaries are defined by lines mid way between the
paths. The slice velocity is taken as that determined by the path within the slice and the slice
area as the product of the slice height and the (average) width. The upper boundary of the top
slice is the water surface. At the bottom, an additional slice is defined between the bed and a
line half way between the bed and the bottom path. This bottom slice has a weighting factor,
K, normally between 0.4 and 0.8 to allow for the slow moving water near the bed. To reduce
the uncertainty of this factor, the bottom path should be positioned as close to the bed as
practical.

1.2.5.2 Mean section method
In the mean section method, the slice boundaries are defined by the path heights themselves.
The slice velocity is taken as the mean of the upper and lower paths which define the slice
boundaries. The upper boundary of the top slice is the water surface.
The velocit y of the water surface, Vs, is given by:-
Vs = V
Where Ks is a multiplying factor normally between 0 and 1 to allow for the projection
of velocity to the water surface
Vs is limited to a value of V
The lower boundary of the bottom slice is the bed. This bottom slice has a weighting factor,
, normally between 0.4 and 0.8 to allow for the slow moving water near the bed.
K
B
The mean section method is superior in cases where the paths are not near the slice centres,
but the mid section method handles the top slice better. The more paths that are deployed,
the less the differences matter.
The mean section method is illustrated in the following diagram:

1.2.6 Path configurations
The simplest arrangement is to have a number of paths “in line” above each other. This
would be suitable for a channel of regular cross section shape, which is straight for a long
distance compared with its width (5 to 10 times).
Other configurations are often used in other circumstances. For example:
• Crossed paths where there is uncertainty about the flow direction
• Sloping paths where the de pth is greater on one side compared with the other
• Transducers inset from the banks
• Multiple sets of paths for compound channel shapes
• V configuration used to divide the width because of size or uneven profile
• Multiple channels
• Reflected paths where transducers are on one side only and reflectors “bounce” the
sound pulses back from the far side. This method saves cable but increases path lengths
and is very sensitive to misalignment.
The Sarasota 2000 flowmeter is capable of being configured for these and many other
situations. Please consult Thermo Fisher Scientific for examples and advice.
1.2.7 Transducer frequency
Transducers are manufactured with characteristic frequencies. These will be in the range 1
MHz to 100 kHz. For propagation reasons, the greater the path lengths the lower the
frequency and the larger the transducer. As a guide, path lengths below 10 metres would use
1MHz transducers, 10 to 80 metres 500 kHz, 80 to 150 metres 250 kHz. These figures are for
guidance and the selection may be influenced by other factors relating to the application. For
example, lower frequency transducers may be used to improve penetration in conditions of
high suspended solids provided there is sufficient depth and velocity.
Please consult Thermo Fisher Scientific for advice.
1.2.8 Minimum depth of water
In order to avoid reflections from the bed or surface causing distortion of the ultrasonic
signals, a minimum height of water is necessary above each path. This depends on the
transducer frequency and the path length.

= 27 √ ( L / ƒ )

A similar restriction applies to the channel bed, particularly if it is smooth and reflects rather

1.2.9 Performance estimates
ISO 6416 describes how to estimate the uncertainty of measurement in any particular
installation. Please consult Thermo Fisher Scientific for advice on this.
1.3 Implementation of the principles of operation in the Sarasota 2000
The principles described in Section 1.2 are used by the Sarasota 2000 subject to certain rules
as listed below. See also Appendix 1:LCD Screens and Appendix 2:GAFA Screens that
describe in detail how the flowmeter is programmed via the LCD screen or PC. Note that the
Sarasota 2000 is a multi-channel device and so paths and levels may be allocated to up to 4
different channels. Overall “station” information (“S” screens) should be entered before
individual channel data (“C” screens). The comments below are how the flowmeter treats
each channel. There are some exceptions, for example, measurement units and flow method
which are common to the station.
Flow
• There is a choice of mean or mid section method of flow calculation.
• The channel cross section shape is entered as a height/width table independent from the
path lengths and angles. (For rectangular or trapezoidal channels it is only necessary to
enter 2 points to define the channels.) The separate table allows the path velocities to be
applied to more accurate slice areas since the defined shape is used rather than a fixed
width for each slice as specified in the Standard.
• Where no path velocity is available, for example at low water height, flow may be inferred
from water level. This is done via a flow estimation table, which may be derived
empiricall y o r by calculation.
Velocity
• The upstream velocity transducers are connected to the upper row of connectors,
downstream to the lower row.
• Path numbering is from the bottom.
• Paths are automatically brought into operation according to the water level and the
programmed minimum water cover.
• Paths entered as being at the same height are taken as crossed, otherwise they are
separate.
• Separate paths may be “normal” with transducers on each side or “reflected” with
transducers on one side only. The latter method saves cable but is not recommended
because of the increased path lengths and sensitivity to alignment.
• The velocities calculated by a pair of paths comprising a crossed path are averaged and
the average velocity used for the slice. The velocity calculated by a separate path is used
alone for the slice.
• When a velocity path fails, the slice boundaries automatically adjust to use only the
working paths.
• A failed path will show on the status indicated on screen C11: Instantaneous Flow &
Level. The path status is a percentage of the “instantaneous” transducer firings which
result in successful reception. If this figure drops below 12% the path is considered to
have failed during the corresponding instantane ous cycle time and is discarded for that
cycle. This could be the result of a fault, misalignment or obstruction.
• Only valid velocity paths which are in the water and covered by sufficient water to be
operating are used for the status indication.
• Each path may have a multiplying factor (“X Factor”) assigned to it. This will normally be 1
but may be different in exceptional circumstances for calibration purposes. An example of
when this might be is when the transducers are not exactly at the channel edges .
• Transducers in each velocity path may be set to operate simultaneously (the norm) or
sequentially. Simultaneous operation allows more measurements in a given time but
INTRODUCTION
Section 1 INTRODUCTION Page 1-7
Thermo Fisher Scientific
Page 18
Sarasota 2000 Ultrasonic Multipath
Flowmeter
there is a small possibility of confusing a signal reflected back to the firing transducer with
one received from the opposite transducer.
Water level
• Levels are combined in the following algorithm:
Only non-faulty measurements are used.
Highest and/or lowest are discarded until 3 remain.
The one furthest from the others is dis carded leaving 2.
The remaining 2 measure ments are averaged for arbitrated level if within an
acceptable band defined on screen C20: Channel Configuration.
If not, level determination fails and flow cannot be calculated.
If only 1 level measurement is installed or only 1 is not discarded, it is used as the
arbitrated level.
If not OK, level fails and flow cannot be calculated.
• Levels defined as valid but rejected by the algorithm will be indicated on the level status,
screen C10: Instantaneous Flow & Level.
• Where the flowmeter is installed in a closed conduit which always runs full, the channel
shape is entered in the usual way but there is no need for a level measurement. The
flowmeter is programmed as though it had an encoder level input (section 2.3.3.2.3) with
a reference level at the top of the conduit and a cal. factor of zero.
Transducer and bed levels
All heights may be set to a fixed datum (local or national) or relative to mean bed level. The
former requires a height for the bed and avoids re-entering all path and level transducer
heights in the event of a change to the bed.
General
• “Instantaneous” means the average over the cycle time scale. This defaults to 10
seconds but may be set to 1 minute for large numbers of paths or long path lengths via
screen S22: Station Configuration.
• The average period is the time over which measurements are averaged for the purpose
of output or logged data. If the cycle time is set to 1 minute, the average period cannot be
shorter.
• At the data logging intervals, the averaged values of the selected data are stored.
• Analogue inputs will normally be linear. However, screen C212: Analogue Input allows
non linear characteristics to be entered.
• When operating on an external 12 volt source, for example from a solar panel, power
saving is possible by using intermittent operation. Power consumption in normal and
intermittent modes is quoted in the Appendix 3:Specification
• The LCD display will turn off 15 minutes after the last keyboard operation. This is to
reduce power and prolong LCD life. Pressing any key will turn it on again.

2.3.2 Core items
The enclosur e houses t he followi ng core it ems as well as the opt ional items listed i n Sectio n
2.3.3:
• power supply and status/power management.
• internal battery
• central processor
• display and keyboard
• connectors for transducers and peripheral devices.
2.3.2.1 Power supply
The standard power supply requires a mains input between 85 and 264 volts AC, 47 to 64 Hz,
backed by an internal 12 V battery for operation in the event of AC power failure.
The fuses shown above are 3.15AT (slow blow) for the mains electricity input and 5AF (quick
blow) for the low voltage from the power supply module.
The “POWER” switch isolates the flowmeter and its internal battery from the external (AC)
power source. When switched off, the flowmeter will continue to operate from the internal
battery unless the “ISOLATE” switch is also off. The “ISOLA TE” switc h disco nnect s all powe r
from the flowmeter.
The internal battery is automatically charged by the power supply when external power is
being supplied and the “POWER” switch is on, regardless of the position of the ISOLATE
switch. When the external supply is off the battery is capable of operating the flowmeter for a
minimum of 24 hours. This period will be longer in cases when INTERMITTENT OPERATION
is being used.
Alternatives of 12 V dc and 24 V dc power sources are available as described in Appendix 3:
Specification.
See Appendix 3: Specification for details of power saving through intermittent operation
2.3.2.2 Central processor (CPU)
The central processor carries out the control and timing functions, stores and runs the
operating program and stores the data logs. It controls the status indicator, see “controls and
displays”, Section 2.5.
It also controls the three s erial i/o ports. See section 2.3.2.4
2.3.2.3 Keyboard and display
The keyboard allows the operator to program the flowmeter and to display measurements,
computed results and diagnostic information via the display (see Section 2.5). These
functions may alternatively be performed via the PC based GAFA software (see Appendix 2:
GAFA Screens).

2.3.3 Optional items
The flowmeter enclosure also houses an optional number of the following cards:
• Transducer interface cards (TIFs) (up to 4 may be fitted).
• I/O card (none, 1 or 2 may be fitted)
• Relay (VFC) card (none or 1 may be fitted)
Details are given in Appendix 3: Specification section, but in summary:
2.3.3.1 Transducer interface card (TIF)
SYSTEM COMPONENTS
Fig 4 Transducer Interface Card (TIF)
The flowmet er has capacity for up to four TIFs as st andard. Each one is capable o f being
connected to 2 velocity paths (4 transducers) directly or 8 paths (16 transducers) by multidrop, and 1 ultrasonic depth transducer directly or 4 by multi-drop. Each TIF must have its
address set via the jumper links PL7 shown in the diagram above. The addresses are in the
form of a binary code with the least significant digit at the top of PL7. No link for 0; link present
for 1.
TIF1, card position 9, address 4, PL7 Links 0100

TIF3, card position 7, address 6, PL7 Links 0110
TIF4, card position 6, address 7, PL7 Links 0111
When setting up the flowmeter, the cards and their addresses are programmed via the
keyboard and screens as described in Appendix 1: LCD Sc reens or v ia GA FA as desc ribed in
Appendix 2: GAFA Screens. When a TIF is changed during service, the replacement must
have the same address set.
Section 2, SYSTEM COMPONENTS, Page 2-7
Thermo Fisher Scientific
Page 26
Sarasota 2000 Ultrasonic Multipath
Flowmeter
Each TIF plugs into the main rack and is wired to the back panel co-axial connector pairs A to
H for onward connection to the velocity path transducers and W to Z for connection to
ultrasonic depth transducers at the time of installation. Fig 5 shows the rear panel connectors.
TIF 1 in card position 7 is connected to A and B and to W.
TIF 2 in card position 6 is connected to to C and D and X etc.
Note that the upstream velocity transducers must be connected to the upper row of A to H
and the downstream ones to the lower row.
The standard rear panel allows connections to 32 velocity paths (64 transducers) and 16
ultrasonic depths via “multi-drop” wiring of the smart transducers.
The velocity transducers may be allocated to up to 4 water channels without any restriction
other than the total number and cable lengths. Ultrasonic depth transducers are limited to 4
per channel via multi-drop. See Section 2.4.

2.3.3.2.2 Analogue I/O
Analogue connections are normally 4-20 mA and are made to the screw terminal blocks at the
right of the rear panel. The upper block connects to I/O board 1 and the lower to I/O board 2.
Connections 1 to 6 (upper) and 15 to 20 (lower) are the analogue inputs. Connections 7 to 14
(upper) and 21 to 28 (lower) are the 4-20 mA outputs.
The table whi c h f ol l o ws s hows the connections.
Analogue inputs, 4-20 mA (0-20mA) or 0-5V
The total input range is 0-20mA though analogue inputs are normally set up as 4-20 mA. On
board links LK2 and LK4 may be removed to accept 0 to 5 volts instead (Fig 6).
Each i/p has 3 connections, 18 V excitation, input and 0V.
If the external signal source supplies the power, connections are made to input (4-20 mA +)
and to 0V (4-20 mA-).
If the Sarasota 2000 flowmeter is to power the loop, connections are made to 18V (4-20 mA+)
and to Input (4-20 mA-)
Analogue outputs, 4-20 mA
Analogue outputs are always 4-20 mA.
Each o/p has 4 connections, 18V excitation, +V, -V and 0V.
If the Sarasota 2000 flowmeter is to power the loop, the output will not be isolated. A link is
made between 18V and +V and the 4-20 mA loop is between –V and 0V.
If the external device powers the loop, the output is isolated. The 4-20 mA loop is between +V
and -V
Note For compliance with EMC emissions control, analogue i/o cables should be screened
and the screen connected to one of the 0V pins for each i/o card.
See the following table for connection details.

2.3.3.2.3 16 bit BCD I/O and encoder input
The 16 bit parallel BCD signal may act as either input or output according to the jumper links
LK1 and 3 on the board. See Fig 6. The default condition is for BCD INPUT
example from a shaft encoder counter.
The format is 5 Volt positive logic, though the input can accept inverted logic if specified via
the screens (Appendix 1: LCD Screens).
Handshaking is via strobes STRB1 and STRB2. STRB1 relates to bits 1 to 8 and STRB2 to
bits 9 to 16.
There are two 25 way female D connectors labelled BCD1 and BCD2. BCD1 is connected to
I/O option card 1 if fitted and BCD2 to I/O option card 2 if fitted.
BCD input
• When used as an input, the 4 digit BCD number is normally used as an auxiliary level.
• Operating units are selected via the screens (Appendix 1: LCD Screens) or GAFA
(Appendix 2: GAFA Screens).
• The BCD number may have an offset applied – “level above datum” if B CD zero does not
correspond to the flowmeter zero level.
• The BCD number may also have a scaling factor applied, for example if a BCD
incremental value of 10 corresponds to 5 mm, the scaling factor is 0.5.
• If the scaling factor is given a negative sign, the BCD input will be taken as negative logic
(low is “1”)
• For BCD input, the STRB is pulled low for 0.2 ms by the Sarasota 2000 when it wants
data.
BCD Output
• When used as an output, the function of the 4 digit BCD number and operating units are
selected via the screens (Appendix 1) or GAFA (Appendix 2). Typically the function will
be flow or water level.
•
For BCD output, the STRB is pulled low for 0.2 ms whilst valid data is being presented.
•
BCD output may be uncoded, in which case the BCD number is taken as it appears, or
coded in which case the first digit indicates a range/sign and the remaining 3 digits the
value. The coding is defined as follows:
Coding for flow
The data is represented as a 4 digit number where the most significant digit is the code:
0 = multiply by 10
1 = multiply by 10
2 = multiply by 10
3 = fault condition, no data
4 = negative flow multiply by 10
5 = negative flow multiply by 10
6 = negative flow multiply by 10
The three remaining digits are the three most significant digits of the reading;
e.g. Flow + 4.28 m3/s Output 0428
Flow +34.28 m3/s Output 1342
Flow - 0.15 m3/s Output 4015
Coding for level
The level data is presented as a 4-digit number, representing the last 4 digits of the displayed
value.
e.g. Flow + 4.123 m Output 4123
Flow +52.678 m Output 2678

Encoder input
The BCD connector also provides the means of connection to the two-phase outputs direct
from a shaft encoder as an optional means of depth input. The Sarasota 2000 flowmeter will
count the pulses up and down to track the depth changes. It is necessary to set the pulse
scale, i.e. the distance corresponding to each pulse, and the counter value at a known depth.
See Appendix 1: LCD Screens (screen C213: Encoder Input Configuration) for the method of
setting up.

2.3.3.3 Relay (Volt free contact) card
The relay card consists of 4 programmable relays and a fa ult relay wit h both normally open
and normally closed contacts. The connections are accessible by removing the cover plate on
the side of the plinth.
Fig 7 Relay connections
The function of each relay is specified by the operator. See Section 2.5.2 and Appendix 1:
LCD Screens.
For example, relay 2 coul d be programmed as a high flow alarm to switch on at a high flow
and off again at a lower value (hysteresis).
Note that if pulses are required for an external totaliser, the selection is limited to relay 1 on
the relay card. However, the standard relay may not be suitable for this if the pulse rate is
high. For this reason the relay card is being changed so that a solid state relay will replace
relay 1. The switching capacity will be lower but the pulse rate will be higher and there will be
no specified limit on the number of operations. Relay 1 will then only have “normally open”
connections. See Appendix 3: Specificat ion.
Please consult Thermo Fisher Scientific if in doubt about which type is fitted.

2.4 Ultrasonic transducers
Each velocity path requi res two transducers and each ultrasonic depth requi res one.
The transducers are available in a number of frequencies. See Section 1.2.6 for frequency
selection. The frequency of the ultrasonic depth transducer, if used, is not normally critical.
1 MHz is usually used if the velocity transducer frequency is 1 MHz or 500 kHz otherwise.
The diameter of the transducer is different for different frequencies. This is to maintain the
angular spr ead of the beam which is a function of frequency and di ameter.
The transducers for the Sarasota 2000 are “smart”, with local circuits for the drive voltage
(HT) generation and the receiver amplifier built in to minimise losses and optimise signal-tonoise ratio. In the case of the 1 MHz transducers the size of the transducer is limited and the
local circuit is separated from the transducer in a potted in-line housing called a “Tbox”,
Transducers may be wired individually to the flowmeter (rear panel connections A to H for
velocity and W to Z for depths) or, using the multi-drop method, via “star” junction boxes in
each transducer array. In the latter case up to 4 transducers may be joined to each rear panel
connector. A mixture of multi-drop and direct connections may be used. For example, if there
are 5 transducers in an array, 4 may be wired via a star box and the fifth wired directly.
The maximum capacity with direct connections is 8 paths and 4 ultrasonic depths.
The maximum capacity with multi-drop is 32 paths and 16 depths.
The transducers have programmable addresses. Addresses 1 to 4 are normally used. When
using multi-drop, the transducers connected to each star box must be pre-programmed with
different addresses to enable each one to be operated separately by the flowmeter. Specialist
equipment is necessary to programme the transducers and it is usual to supply them with
specified ad d r esses.
2.4.1 1 MHz transducers
For use with path lengths up to 10 metres. In cases where serious attenuation is anticipated
(for example, sewage) it is recommended that the use be restricted to 5 metres and a lower
frequency be used above that. Of course the lower frequency requires a greater depth of
water in which to operate and this must be taken into account (see Section 1).
An in-line Tbox is fitted in line with each transducer.
The co-axial cable from the T box must be connected t o a star b ox or exten ded to run direc tly
to the flowmeter. Coaxial cables to the flowmeter enclosure are usually made up on site.
Cables may be supplied to length with made up ends if specified with the order but this often
makes the installation more difficult where there is the need to pull cables through ducts.
2.4.2 500 kHz Transducers
For use with path lengths above 10 metres. In cases where serious attenuation is anticipated
(for example, sewage) it is recommended that 500 kHz transducer be used above 5 metres.
At the upper end, they may normally be used up to 80 metres. For cases where serious
attenuation is anticipated, lower frequency transducers should be used for paths above 50
metres.
SYSTEM COMPONENTS
Section 2, SYSTEM COMPONENTS, Page 2-15
Thermo Fisher Scientific
Page 34
Sarasota 2000 Ultrasonic Multipath
Flowmeter
The 500 kHz transducers have the HT and signal amplifiers built in. They are connected
directly to the flowmeter or via star boxes. If ultrasonic depth transducer(s) are being used, it
is usual to use 500 kHz frequency when that frequency is being used for water velocity
measurement.
The transducers are supplied with 5 metres of cable which is connected to a star box or
extended to run directly to the flowmeter. Coaxial cables to the flowmeter enclosure are
usually made up on site. Cables may be supplied to length if so ordered with made up ends
but this often makes the installation more difficult where there is the need to pull cables
through ducts.
2.4.3 Lower frequency transducers
Consult Thermo Fisher Scientific about low frequency transducers for path lengths above 80
metres or where conditions might attenuate higher frequency signals.
If ultrasonic depth transducer(s) are being used, it is usual to use 500 kHz frequency when
lower frequency transducers are being used for water velocity measurement.

2.5 Controls and displays
2.5.1 Panel layout
Fig 1 shows the layout of the front panel. It contains the keyboard and liquid crystal display
(LCD). The keyboard is used to access the LCD and to:-
• programme the flowmeter with site data, for example. path lengths, angles, heights
• set up the inputs and outputs (including simulation for test purposes)
• set up the relay functions and values on which to switch
• display ultrasonic waveforms
• display measurements and results
• display diagnostic data
2.5.2 Screen organisation
The LCD screens are all numbered as listed in Appendix 1: LCD Screens.
The screens are arranged in levels, the lower levels being selected and accessed from the
one above.
When a lower level is displayed, it overlays the one above so that each is visible.
The ARROW keys move a highlighted area around each screen.
The ENTER key actions the highlighted instruction, for example to select a lower level screen.
The ESCAPE key reverts to the previous screen.
When the highlighted box requires data, the NUMBER keys are used.
The ENTER key st or es t ha t da t a in me m ory.
There are 4 FUNCTION keys at the bottom of the screen. Their function changes according to
what is dis played above them on the screen.
The display goes blank to save power 15 minutes after the last key stroke. Pushing any key
powers it up.
2.5.3 The status in dicator
The status indi cator operat es as fo l l o ws:
• Continuous green – contentment
• Continuous red – alarm condition exists or has occurred earlier and has not been
acknowledged. The meaning of this is defined by the user via screen S30: Fault Relay
Configuration, and details of the fault can be identified in screen S10: Fault Status (for
example, all faulty ultrasonic paths or depth paths).
• Either light flashing evenly – running on battery.
• Either light “blipping” on intermittently – running in power save intermittent mode.
• No light at all – power off and battery run down.
With the alarm reset key the operator acknowledges the alarm and resets it.
The operation and setting up are described in Section 4: Installation, Appendix1: LCD
Screens and Appendix 2: GAFA Screens.
Note that the GAFA PC software provides similar facilities either locally via the front RS232
connector or the IR link, or remotely via a modem.

2.6 Software & firmware
There are 2 types of software:
• The internal pre-loaded operating software, normally called “firmware”
• The PC software for communicating with the flowmeter, called “GAFA”
2.6.1 Operating firmware
The flowmeter is supplied with the operating firmware already loaded. It would not normally
be necessary to re-load the firmware. In the event that new firmware is to be loaded, Thermo
Fisher Scientific will provide the procedure or carry out the operation.
2.6.2 “GAFA” PC software
An optional facility is the GAFA software, which runs on a PC under Windows. This allows
communication with the flowmeter:-
• Via the RS232 port on the front of the plinth
• Via the IrDA link on the front panel
• Remotely via a modem connected to the RS232 port on the rear of the plinth
The functions possible via GAFA are:-
• S etting up the flowmete r in the same way as v ia the flowmeter control s and display as
described in 2.5 but with the benefit of superior PC display
• Interrogating the flowmeter for measured parameters and calculated results as 2.5 with
the same benefit
• Downloading logged data.
Appendix 2: GAFA Screens des cribes the GAFA.
2.7 Documentation
In addition to the hardware described in 2.3 and 2.4, and possible peripheral equipment, the
following documentation may also be supplied:
• A copy of this ma nual (additional copies m ay be supplied)
• Site specific data (Appendix A5: Site Data). Configuration and program data completed
by installation and commissioning engineers.
• Site specific drawings – transducer mounts, site layout, civil details (if part of contract)
• Certificate of conformity (specific test sheets available on request)
• Certificate of approval for Quality Management Sys tem
• On site calibration certificate (if included in the installation contract)

4.1 Safety
SAFETY NOTICE
The installation of the Thermo Scientific Sarasota 2000
flowmeter may involve a number of steps which require
special skills, training and special equipment. Examples
include:
• Electrical installation
• Working on construction sites
• Working near water (may be deep or fast flowing)
• Lifting equipment
• Working at height
• Working from boats
• Confined space working
It is recommended that prior to the installation the installer
should write a method statement detailing:
• The scope and purpose of the work,
• The steps in the operation,
• Interaction with others,
• The personnel to be involved,
• Their qualifications for the work,
• Protective clothing and equipment,
• Machinery, tools etc.
• Emergency contacts and procedures.
A risk assessment should be carried out and both the
method statement and risk assessment should be
approved by the person responsible for Health and Safety
on the site.
Thermo Fisher Scientific accepts no responsibility for the
safety of personnel other than its own employees in the
installation and commissioning of the Sarasota 2000
flowmeter and accessories supplied.

4.2 General
It is usually necessary for some preparatory work to be carried out prior to installation of the
flowmeter system. This work is often performed under a separate contract and typically
includes:-
• Installation of supporting structures for transducer mounts, for example, piles in a river,
brackets on concrete channel walls.
• Installation of ducts o r cable tray for the interconnecting cables.
• Installation of a suitable housing for the flowmeter and peripheral equipment. This could
be an existing building or a kiosk.
• Provision of a power supply.
• Provision of a PSTN connection.
The installation of the equipment on site follows the above. It is normal practice to carry out a
risk assessment and to write a method statement to be agreed by the client before startin g
work. The installation work is often restricted to times when suitable site conditions apply.
It is recommended that the installer of the flowmeter should inspect the preparatory work prio r
to mobilising resources for the installation.
4.3 Unpacking and laying out
If site and general assembly drawings were specified as part of the supply contract they will
normally have been supplied and accepted prior to delivery of the equipment. The drawings
will be a useful guide to checking the inventory of equipment delivered.
The equipment supplied should be carefully unpacked and checked for content and damage.
The transducers may have been supplied in rack assemblies ready to be installed to the
supporting structure. There will normally be two or four racks (for in-line or crossed paths). In
large channels or those with complex shapes, there may be more than two racks, for
example, in a stepped channel with a low level channel and a wider high one.
If the racks have not been assembled, this may be carried out on site according to the
assembly drawings.
It is important to check that sufficient cable has been supplied for connecting transducers and
that suitable fixings for all the items have been supplied or separately procured.
4.4 Installing transducer assemblies
WARNING – Installing transducer racks may involve working near deep or
contaminated water and/or in confined spaces. Appropriate precautions and suitably
qualified personnel should be used.
The transducer rack assemblies should be installed in their prepared positions according to
the drawin gs and method statements.
Care must be taken not to damage the coaxial cables during this operation.
See Section 2.4 for transducer and junction box configuration.
Depth gauge transducers or transmitters may be fitted to one or more of the transducer racks
or have a separate fitting.
INSTALLATION
Section 4 INSTALLATION Page 4-2

Sarasota 2000 Ultrasonic Multipath
Flowmeter
4.5 Connecting transducers to flowmeter
Cables for the ultrasonic transducers should be labelled for identification, cut and pulled
through the ducts or laid in trays back to the flowmeter. Connectors should be fitted to each
end according to the instructions supplied with the connectors.
Where 1 MHz transducers are being installed, the connections are via the transducer boxes
(see Section 2.4.1) which are fitted at the rack assemblies.
Cables for depth gauges other than Sarasota ultrasonic transducers should also be pulled
back to the flowmeter. Gene rally, if the de pth gauge is a pres sure transmitt er, the attached
cable will be supplied long enough for this purpose without joining.
The transducer cables are to be terminated at the flowmeter end and plugged in to the
flowmeter back panel as shown in Section 2.3.3.1.
Ultrasonic path numbers are as shown, numbered from the lowest path. If 2 paths are at the
same height the firmware will take them as crossed for the purposes of slice allocation and
flow calculation (see 1.2.5). Upstream transducers should be plugged into the upper row on
the back panel and downstream ones to the lower.
4.6 Transducer alignment
At this stage it is usual practice to align the transducers. Each transducer should point at its
partner to within ±1
• Pre-set alignment derived from construction drawings.
• Visual methods involving pointers and sighting arrangements.
• Low power laser methods.
If the transducers are in the water, only the first of these may be possible and final adjustment
should then be carried out by adjustments to maximise signals during commissioning.
4.7 Output connections
Output signals should be wired to the peripheral devices according to the connection tables
given in section 2.3. In some cases standard cables will hav e been provided, eg RS232, or
pre-made cables will have been ordered as part of the contract.
Note For compliance with EMC emissions control, analogue, BCD and serial i/o cables
should be screened and the screen connected to a 0V pin. Where the connector is a ‘D’ type
connector, the screen may alternatively be connected to the connector body if metal.
4.8 Power Connection
Connection should be made to the external power source according to local or national
regulations. The flowmeter is supplied with a standard 230 volt mains cable for connection to
an AC source in the range 85 to 264 volt AC, 47 to 64 Hertz. This may be connected to the
power outlet via a plug or, more usually via a switched spur. This work should be carried out
by a person with the appropriate qualifications.
See the site data book for details of flowmeters supplied for DC operation.
o
. The method used will vary according to the conditions.

COMMISSIONING
5 COMMISSIONING
5.1 Site dimensions
If this information is not already available, it will be necessary to carry out a dimensional
survey of the installed transducers and the channel in order to programme the flowmeter. It
will be necessary to determine the following:-
• length, angle and the heights of each path,
• average cross section profile, if different from that defined by the paths,
• mean bed level (MBL),
• height offset of the level transducers and,
• relationship between the local heights and a fixed datum if not
MBL.
This manual does not cover surveying techniques. However, for small sites physical
measurements are easily carried out by measurement with a tape. Angles may be determined
by triangulation.
5.2 Powering up
Check that the flowmeter contains the specified modules and the cards are plugged in to the
correct rack positions, see Section 2. Also, Appendix 5: Site Data may already have been
partially filled in prior to shipping to indicate the card positions.
Switch on the power source and ensure that the internal power switch is on (Section 2.3).
The main STATION HOME screen will be displayed (Appendix 1: LCD Screens).
5.3 Programming
The flowmeter should be programmed as described in Appendix 1: LCD Screens.
Alternatively a PC may be used rather than the built-in screen and keyboard as shown in
Appendix 2: GAFA Screens. The programme details should be recorded to become part of
Appendix 5: Site Data.
Appendix 5: Site Data is a useful checklist covering all programmed data, some of which may
not be required for any particular site.
5.4 Setting up
5.4.1 Ultrasonic levels
Select “Manual” and set the gain and voltage for each level (screen C216: Level Transducer
Setup) to obtain a clean waveform and detection point (screen C218: Level Waveform
Display).
5.4.2 Auxiliary levels – analogue input
Set the input range via screen C212: Analogue Input Configuration. This allows the input to
be linearised, but most level devices will be suffic iently linear and only n eed 2 points to define
the input. On the table, define 4 mA as the minimum, 20 mA as the maximum and enter the
depth offset (level above datum).

Page 44
Sarasota 2000 Ultrasonic Multipath
Flowmeter
5.4.3 Auxiliary level – encoder input
Screen C213: Encoder Input Configuration allows the details of a direct input from a shaft
encoder to be programmed. This involves setting a point of reference from which to count up
and down (the current level) and the scaling factor of pulses per unit of depth.
5.4.4 Auxiliary levels – BCD input
Screen C214: BCD Input Configuration is used to define the relationship between the BCD
input and actual depth. The level of the counter zero above datum is entered and the
conversion factor relating counter value to the depth units.
5.5 Outputs
The outputs are selected from analogue, BCD and relays. (Set up via screens S25: Output
Configuration, screen S250: Analogue Output Configuration, screen S251: BCD Output
Configuration and screen S252: Test Output Configuration).
Correspondence between the displayed selected parameter value and the output should be
checked. It is possible to force the outputs by temporarily changing the set-up, for ex ample
changing the level datum will affect not only the apparent level measurement but also the
flow. Alarm thresholds may be altered to check relay operation.
Analogue outputs may be checked by a calibrated multi-meter and verified as being received
by the destination device.
BCD outputs are more difficult to check with a multi-meter and are usually verified by reading
the destination device. A BCD test box with a display is available through Thermo Fisher
Scientific.
Alarm outputs may be checked by a calibrated multi-meter and verified as being received by
the destination device.

CALIBRATION/
VERIFICATION
6 CALIBRATION/VERIFICATION
Flowmeters of this type do not normally require calibration. Exceptions are where there are
significant unmeasured areas, for example, behind transducers, or where local conditions
might create atypical velocity profiles and a small number of velocity paths are deployed. See
Section 1: Introduction and Appendix 4: References.
However, it is normal to carry out periodic checks to verify the overall performance of the flow
determination.
Whether for calibration or verification purposes, the comparison method to be used will be the
same and will depend on the site.
Reference is made to ISO 748 for details of methods. See Appendix 4: References.
The most common method used is by current metering using a calibrated rotating element or
electromagnetic current meter.
Care should be taken to use repeated checks and to minimise the experimental uncertainties
which could otherwise be greater than the uncertainty of the ultrasonic flowmeter.

MAINTENANCE
7 MAINTENANCE
There is little maintenance as such relating to the flowmeter itself. However, the river or
channel must be kept free of weed, silt and other obstructions to avoid interruption of the
ultrasonic paths or changing the cross section area which would affect the accuracy of flow
determination.
Periodic checks on the functioning of the flowmeter and verification of the flow as calculated
are recommended.
7.1 Channel maintenance
7.1.1 Weed
• If weed tends to grow in the channel, it must be kept cut.
• Weed must be kept clear from between the transducer arrays where it may stop the
passage of sound between the transducers.
• Weed should also be controlled on the approach to the gauged section and immediately
downstream of it where its presence c ould distort the velocity profile.
The user must decide on the season al cu t t i n g re gime to suit the ch an n el .
7.1.2 Profile
Periodically the channel shape should be checked to determine whether it has changed since
the flowmeter was programmed. It is particularly important to check the bed where silt might
have been deposited or scouring could have occurred.
Changes may be required to the programmed channel shape or mean bed level.
In serious cases, it may be necessary to dredge the channel, taking care not to damage the
transducers.
The user must decide on the che cking regime to suit the channel.
7.1.3 Debris
Under high flow conditions it is not uncommon for debris to be washed along the channel.
Whilst the design of the transducer supports should be such as to minimise the risk of
snagging this debris, separate deflectors or devices intended to capture it may be employed.
If the channel is prone to this phenomenon, the user must instigate an appropriate debrisclearing regime.
7.2 Flowmeter maintenance
There are no parts requiring maintenance except that the transducers should be checked
occasionally for a build-up of surface coating, for example by grease, and for misalignment
caused by physical shocks. These checks may be carried out along with the channel
maintenance.
Normally it is possible to obtain advance warning of problems by checking the signal quality.
This may be done on site or remotely via GAFA (Appendix 2: GAFA Screens).
Section 7, MAI N T E NANCE Page 7-1
Thermo Fisher Scientific
Page 48
Sarasota 2000 Ultrasonic Multipath
Flowmeter
7.3 Routine checks
7.3.1 Remote
Remote checks of operation of all velocity paths and depths are easily carried out via GAFA.
It is recommended that a monthly routine should be set up to handle this.
If the flowmeter is fitted with the relay option, one of the relays may be programmed to initiate
an early warning call via a telemetry outstation.
7.3.2 On site
It is recommended that an annual check be made on site. This should include:
• A visual observation of the equipment in the channel and the flowmeter.
• A functional check of the operation of the paths, levels and outputs.
• A c h ec k on t he operation of the i nternal battery .
• A verification of calculated flow by a comparison method, see Section 6: Calibration
Any corrective work should be taken at the time if possible or reported for subsequent action.
