FLOW-meter
Manual Version 1.0
Introduction
The FLOW-meter measures the fuel consumption of models with turbine, which are made
available for transmission on the telemetry return channel of the respective remote control
system. The model pilot is thus always informed about the current consumption / tank level.
Depending on the remote control system, alarm thresholds (reserve, turbine OFF) can be set in
the transmitter or in the FLOW-meter. The consumption / tank level can reseted via a separate
servo channel - so displaying the actual consumption / tank level would not be a problem even
after a so-called "taxi tank" has been disconnected after the start phase.
With Jeti, HoTT and PowerBox, the FLOW-meter settings can be made directly from the
transmitter, with all other remote control systems using a micro SD card.
The VSpeak FLOW-meter is available in 4 versions:
FLOW-meter 1.0 for turbines up to 180N
FLOW-meter 1.6 for turbines up to 300N
FLOW-meter 3.0 for turbines with an integrated pump or > 300N
FLOW-meter E without sensor, for customer flow sensor.
Since the electronics of the FLOW-meter has an easy-to-use calibration function, it is also
offered in the "FLOW-meter E" variant without a sensor, for any sensor that may already be
provided by the customer, which provides a digital output signal as an NPN open collector.
This is the case with a large number of BIO-TECHsensors.
For the fuel connections, you can choose between Festo push-in fittings for 4 or 6 mm hose -
or Festo screw nipples for 6 mm hose. We recommend screw nipples "in suction mode" - on
the suction side of the pump.

The blue LED is blinking every second to signal the normal function of the Flow-meter.
The connection between the FLOW-meter and the remote control system is made
with the 3-pin servo patch cable except in the case of Spektrum, there with the special cable
(see following pictures):
The FLOW-meter can be connected to a servo port of the receiver using the 1-pin
servo patch cable –servo > 80% resets the FUEL value.

From the large number of available flow sensors, we have made a selection with which the
necessary measuring range for the turbines used in model building can best be covered.
The flow sensors available from us all look the same on the outside, but differ in nozzle size
and number of pulses per 1000 ml. The following table contains extracts from the data sheets
of the flow sensors:
Nozzle in
mm
Impulses/1000ml
Flow range

1,6
~6800
25…2500
+/-2%
FLOW-meter 3.0
3,0
~5000
50…3000
+/-2%
Our recommendation:
FLOW-meter 1.0 for turbines up to 180N
FLOW-meter 1.6 for turbines up to 300N
FLOW-meter 3.0 for turbines with an integrated pump or > 300N
Whenever possible, the flow sensor should be arranged as follows:
Pump -> Filter -> FLOW-meter -> (Valves) -> Turbine
In the case of turbines with an integrated pump, the next larger flow sensor with the larger
nozzle should be selected if possible in order to keep the resistance in the suction line as low as
possible. Festo screw nipples should also be used here instead of Festo push-in fittings, since
the latter are not so well suited for suction operation
The decisive factor for the accuracy of the FLOW-meter is how exactly the impulses / 1000 ml
are determined and stored as parameters in the FLOW-meter. Since a variety of factors, such
as The tubing and installation position play a role, it is in any case necessary to
adjust the number of pulses in the final installation location ... to
achieve the specified accuracy of +/- 2%. For this purpose, the FLOW-meter has a calibration
option, see section 2.0.3.
The flow sensor can be installed in any
position - but the direction of flow must be
observed.
The flow sensor can be mounted to a frame or mounting plate using the screws included in the
scope of delivery, using the holes provided on the underside of the flow sensor.
The FLOW-meter can be attached using Velcro tape, double-sided adhesive tape, cable ties or
similar.

2Telemetry
The voltage for the FLOW-meter is supplied by the receiver.
The Button of the FLOW-meter can be used to switch between the systems Jeti Duplex,
Multiplex, HoTT, Futaba, FrSky, JR PROPO, PowerBox and Spektrum, s. section 2.0.1.
2.0 Settings
2.0.1 Selection of the telemetry system
When you turn on the Telemetry System is signaled by a LED for a period of 3 seconds. While
the blue LED flickers, the data LED shows the chosen telemetry system:
green Jeti Duplex EX (s. section 2.1)
red Multiplex (s. section 2.2)
green (flickering) HoTT (s. section 2.3)
red (flickering) Futaba S.BUS2 (s. section 2.4)
green (flashing) FrSky S.Port (s. section 2.5)
red/green (flashing) JR PROPO (s. section 2.6)
red/red/green (flashing) PowerBox (s. section 2.7)
red (flashing) Spektrum (s. section 2.8)
Double-click on the Button (similar to the double click of a computer mouse), the telemetry
system can be switched.
To preserve safety during the selection of the telemetry system, the FLOW-meter does not
transmit any information until a restart.
The setting is saved.
2.0.2 Parameter file "FLOW.TXT"
With the remote control systems Jeti Duplex, HoTT and PowerBox the parameterization can be
done directly at the transmitter, for all other systems the parameter change can be made via the
file "FLOW.TXT".
By inserting an SD card (without file "FLOW.TXT") into the Micro SD card slot of the
FLOW-meter and switching on the FLOW-meter, the FLOW-meter recreates the file
"FLOW.TXT" with the parameters currently set in the FLOW-meter. Now you can look at the
parameters in the "set value" column of the "FLOW.TXT" file using an editor (Windows
Accessories / Editor) and change the values. The parameters are largely self-explanatory, the
permissible value range is in the "value range" specified. To change the parameters in the
FLOW-meter, the modified "FLOW.TXT" file is now reinserted into the SD card slot and the
FLOW-meter is switched on.
The Data LED green/red signals the status of the Read/Write process of the SD card:
red flashing: Card not readable by the FLOW-meter
green flashing: Writing / reading the parameter file "FLOW.TXT" -> OK
green/red flashing: Parameter transfer of "FLOW.TXT" incorrect
With green / red flashing, not all parameter changes have been accepted in the FLOW-meter,
e.g. because of invalid characters or values outside the range "value range". The FLOW-meter
then re-created the "FLOW.TXT" file with the data currently stored in the FLOW-meter. You
should look at it again in the editor and compare it with the parameter changes you have in
mind.

Global parameters
general
Pulses/1000ml
Parameter for adapting the FLOW-meter electronics to the respective flow sensor (s.
section 2.0.3 Calibration).
FUEL Tank Size
Volume off the main tank in ml.
FUEL display
Here you can choose whether FUEL should display the increasing fuel consumption
(consumed) or the falling tank content (level).
FUEL rounded
The display accuracy of FUEL (ml) can be set here.
Rounding the display makes sense, when using speech to reduce the announcement
syllables.
Auto Reset
With Auto Reset = Power ON, the consumption / tank display is reset to 0 ml (FUEL
display = consumed) or FUEL Tank Size (FUEL display = level) each time the
receiving system is switched on.
With Auto Reset = OFF the last value is stored and is available again after the
receiver is switched on again until a reset at the servo input (> 80%).
alarms
FUEL Reserve
Alarm when the value falls below the value set here. (OFF ... no alarm)
Flow MIN
The FlowMIN alarm is signaled when the current fuel flow set under FlowMIN is
undershot.
This alarm can therefore be used to detect turbine OFF.
The turbine OFF monitoring is started after the value set in FlowMIN has been
exceeded for the first time. (OFF ... no alarm)

FLOW-meter Version: 1.0 www.VSpeak-modell.de Page 9/29
2.0.3 Calibration
The accuracy of the FLOW-meter depends on the accuracy of the Impulse / 1000ml
parameter. Information on this can be found in the flow sensor data sheets of the respective
manufacturer, but these are often to be understood as a "guideline value", can vary both within
a production batch, as well as from the medium and the respective installation position.
Therefore a calibration is absolutely perform.
Notes for performing the calibration:
In the case of turbine models, connect a hose to the outlet of the flow sensor and feed it
directly into a measuring cup. Now with most turbine ECUs, the pump test mode can be
activated and the desired amount of fuel can be fed into the measuring cup by the flow
sensor.
It should be calibrated at medium pump output.
Instead of a measuring cylinder / measuring cup, a scale can of course also be used for
the calibration - taking into account the density of the respective fuel for the conversion
ml -> gram (..., e.g. 1000ml kerosene = 800gram)
The calibration can be done in different ways:
2.0.3.1 Auto calibration 1000ml
With a long press (> 2 seconds) the auto calibration mode is activated, signaled by
green LED ON and blue LED OFF (FUEL and FLOW values do not change during the
calibration mode).
Now the FLOW-meter pumps exactly 1000ml into a measuring beaker, the flow is signaled by
the flashing red LED.
The calibration mode is ended by pressing the button again. The FLOW-meter works again in
normal operation, indicated by the blue LED flashing every second.
2.0.3.2 Calibration –arithmetic
Set the display of fuel to "consumed" (in the delivery state) and the FUEL display to 0ml.
Pump any sufficient amount of fuel through the flow sensor into a measuring cup.
The new parameter Impulse / 1000ml is now as follows:
display FUEL (ml)
Impulse/1000ml (new) = -------------------------------------- * Impulse/1000ml (until now)
level measuring cup (ml)
2.0.3.3 Calibration –live
With the Jeti, HoTT and PowerBox systems, you can carry out the calibration for any
sufficiently large fuel rate "live".
Set the fuel display to "consumed" (in the delivery state) and the FUEL display to 0 ml.
While you are pumping, you can synchronize Pulses / 1000ml display in the FLOW-meter to
the measuring cup by adjusting the parameter.

FLOW-meter Version: 1.0 www.VSpeak-modell.de Page 10/29
2.1 Jeti Duplex EX
2.1.1 EX-Daten DC/DS-radios
The EX-Protocol is partially backwards compatible. On older non-EX devices you get only
Jetibox functions. On EX devices like the DC/DS radios and the Jeti "Profibox" you get
additional data:
FUEL consumed/tank level in ml
FUEL% consumed/tank level in %
FLOW current fuel flow in ml/min
The display for FUEL / FUEL% is adjustable:
increasing = consumed
descending = level
2.1.2 Jetibox
The Jetibox buttons have the following
functions in the data display of the
FLOW-meter (see picture on the left)
left-Button: long pushed Return to the expander menu
(if FLOW-meter is connected together with other
sensors via an expander)
down- Button: Setup FLOW-meter (s. section 2.1.2.2)
left/right- Button: long pushed Reset FUEL and FUEL%
2.1.2.1 Expandermenu
If the FLOW-meter is connected to an Expander or
Centralbox and the FLOW-meter display is activated with
the Right button, the only way back to the expander
menu is pressing the Left button (more than 3 sec).

FLOW-meter Version: 1.0 www.VSpeak-modell.de Page 11/29
2.1.2.2 Alarms / Parameterization
From the data display, the parameter display can be accessed by pressing the
Down button.
With the Up button the parameter display will left.
Within the parameter display you can scroll with the Right button - or - Left button
between the parameter groups "FUEL Tank Size", "Pulses/1000ml", "FUEL display",
"FUEL rounded" , "Auto Reset" , "Alarm" , "Alarmcode" und "FLOW-meter-EX-Name".
When the desired parameter group is selected, the parameter can be changed by using
Down and Up button.

FUEL Tank Size
Volume off the main tank in ml.
Pulses/1000ml
Parameter for adapting the FLOW-meter electronics to the respective flow sensor (s. section
2.0.3 Calibration).
FUEL display
Here you can choose whether FUEL and FUEL% should display the increasing fuel
consumption (consumed) or the falling tank content (level).
FUEL rounded
The display accuracy of FUEL (ml) can be set here.
Rounding the display makes sense, when using speech to reduce the announcement syllables.
Auto Reset
With Auto Reset = Power ON, the consumption / tank display is reset to 0 ml (FUEL display =
consumed) or FUEL Tank Size (FUEL display = level) each time the receiving system is
switched on.
With Auto Reset = OFF the last value is stored and is available again after the receiver is
switched on again until a reset at the servo input (> 80%), or in the JetiBox, when displaying
data by simultaneously pressing the Left- AND Right-button for a long time.
Alarme
Irrespective of the possibility to program alarm thresholds for the "EX" values in Jeti
transmitters the FLOW-meter has the ability to set alarms (by using alarm codes). These alarms
can also be announced by the Profibox as voice messages.
As can be seen in the table, the alarms for Reserve and FlowMIN can be switched OFF.
Permanently pending alarms max. 3 times repeated.
Reserve
The alarm Reserve is signaled when the FUEL display = consumed and when [FUEL Tank
Size - Reserve] is exceeded…. or if the fuel gauge falls below (FUEL display = level).
FlowMIN
The FlowMIN alarm is signaled when the current fuel flow set under FlowMIN is undershot.
This alarm can therefore be used to detect turbine OFF.
The turbine OFF monitoring is started after the value set in FlowMIN has been exceeded for
the first time
FLOW-meter EX sensor name
In a 2-turbine model 2 VSpeak-FLOW-meter can be used on Jeti Systems via an expander or
CentralBox. The EX names are:
"1LFLOW " for Left FLOW-meter on input 1and
"2RFLOW " for Right FLOW-meter at the expander input 2.

2.1.3 Profibox - autonomous telemetry system
Using a Jeti Profibox incl. RSat receiver and the VSpeak-FLOW-meter the telemetry data from
a FLOW-meter can be transferred completely self-sufficient to the pilot. Not only the settings
using the Profibox can be made, as was shown in the previous chapters - all EX-data and the
important alarms are displayed: Reserve, FlowMIN. . . are given as voice messages again.

2.3 Graupner HoTT
Using the HoTT System there are 2 ways to transmit telemetry data, on the one hand as "text"
and on the other hand only the pure values.
Using text mode it is possible to establish a bi-directional data transfer, meaning you can use
the keys of the radio or the Smartbox in order to change/enter values in the sensor. Using speech
output is not possible in this mode.
In data-mode the values are only transmitted in a fixed format in one direction. The format is
defined by the sensor type. In this mode it is possible to have speech output for the sensor
values.
2.3.1 Sensortype
The FLOW-meter for HoTT is a GAM (General Air Modul), a ESC (Electronic Speed
Controller) –or a VAR (Vario). Please select this sensor-type on your radio or Smartbox.
2.3.2 Textdisplay
Using the text-display you can see the current FLOW-meter data and you can also change
parameters of the FLOW-meter.

2.3.3 Data-Display/Speech
2.3.3.1 GAM - General Air Modul
The consumption / tank level is displayed on the one hand in ml and on the other hand in percent
or graphically as a bar.
The flow FLOW is output as speed, so 0 rpm corresponds to 0 ml/min.
2.3.3.2 ESC - Electronic Speed Control
The consumption / tank level is displayed on the one hand as a capacity value, i.e. 0 mAh
corresponds to 0 ml. On the other hand, the percentage consumption / tank level is displayed as
current, i.e. 0.0A corresponds to 0.0% consumption / tank level. The tank level is easy to read
on the associated bar display.
The current FLOW and its maximum value FLOW (max) are output as speed, i.e. 0 rpm
corresponds to 0 ml/min.
2.3.3.3 VAR –Variometer
The HoTT Vario offers the possibility to display texts, in the example two lines with an MC20.
The consumption / tank level is transferred as percentage in height value, so 52m corresponds
to 52% fuel (can be used for voice output).

Reserve
The alarm Reserve is signaled when the FUEL display = consumed and when
[TankSize - Reserve] is exceeded…. or if the fuel gauge falls below (FUEL display = level).
FLOW
The FLOW alarm is signaled when the current fuel flow set under FLOW is undershot.
This alarm can therefore be used to detect turbine OFF.
The turbine OFF monitoring is started after the value set in FLOW has been exceeded for
the first time

2.3.4.2 FUEL
Here is the current FUEL display, according to the settings listed below
Settings
Value range
consumed / level
1, 5, 10, 20, 50, 100
OFF, PowerON
50 . . . 20000
GAM / ESC / VAR
Upon delivery, the warning thresholds are set as shown in the picture.
F-display
Here you can choose whether FUEL and FUEL% should display the increasing fuel
consumption (consumed) or the falling tank content (level).
F-rounded
The display accuracy of FUEL (ml) can be set here.
Rounding the display makes sense, when using speech to reduce the announcement syllables.
Autoreset
With Autoreset = Power ON, the consumption / tank display is reset to 0 ml
(F-display = consumed) or TankSize (F-display = level) each time the receiving system is
switched on.
With Autoreset = OFF the last value is stored and is available again after the receiver is
switched on again until a reset at the servo input (> 80%), or in the JetiBox, or in the
Textdisplay by pressing "SET".
Imp/Liter
Parameter for adapting the FLOW-meter electronics to the respective flow sensor (s. section
2.0.3 Calibration).
Sensor
In sensor the sensor type can be GAM, ESC or VAR. The change of the sensor type will
only take effect after restarting the FLOW-meter.

2.4 Futaba S.BUS2
The FLOW-meter converter is fully compatible with S.BUS2. Registration and connection are
established as with any other S.BUS2 sensor.
Caution:
We generally recommend a strict separation between sensor values and servo data. Although
the S: BUS 2 can transmit servo data, the S.BUS2 should exclusively be used for the
transmission of sensor data and only the S.BUS1 should be used for the servos. In this way, the
servo data are excluded from influencing on failure of a sensor.
2.4.1 Registration at the transmitter
The FLOW-meter must be registered on the transmitter like any S.BUS2 sensor.
The slot allocation is required only once, this can be done manually or by the transmitter.
Manual Slot Allocation:
1. Select the desired sensor at free slot addresses on the transmitter (see Table Assignment
Sensor –FLOW-meter values).
2. Transfer the slot addresses set on the transmitter to the parameter file "FLOW.TXT"
(see section 2.4.4).
Slot allocation by the transmitter:
Connect the Telemetrie Port of the FLOW-meter with to the "S.I / F" socket of the
transmitter.
Now you can register the FLOW-meter - please refer to the instructions of the respective
transmitter. For transmitters without supply voltage at the "S.I / F" socket, a receiver battery
must also be connected via V-cable.
Since the FLOW-meter displays its data using a total of 1 or 2 sensors, the registry has also
be done 1 or 2 times.

2.4.2 Parameter "FLOW.TXT"
Not relevant for Futaba
Start-ID: Here, the sensor ID will be set at which the sensors of FLOW-meter are
registered at Futaba system.
The ID applies to the first Temperatursensor SBS-01T (FLOW), the second
Temperatursensor SBS-01T (FUEL%) then has the Sensor-Start-ID + 1.
A change in the sensor ID can still take place if further SBUS sensors are
registered on the transmitter with randomly the same sensor ID - or even another
FLOW-meter, for example, in a 2- rayed Jet.
Slot …: Here, the StartSlot of each individual sensor can also be set manually: in the
transmitter, the assigned sensor is also to be set manually at the corresponding
slot address (SBS-01T bzw. Temperature).
The corresponding sensor is deactivated with slot "OFF"
- is thus also deactivated for transmitter registry.
Reset Servo: A servo channel can be set here that will reset the FUEL value at > 80% via the
SBus2. The 1-pin patch cable described in section 1 Hardware can therefore be
omitted here.
