VSPeak Modell flow meter Driver
This driver implements support for the VSPeak Modell flow meter sensor.
https://www.vspeak-modell.de/en/flow-meter
Setup
Mode selection
There are two ways to operate this sensor.
A: Save consumed volume
Under this mode, the sensor will remember how much fuel volume was consumed across power cycles. This allows you to have an accurate fuel tank level reading even if you power down or reboot the autopilot.
However, you will have to manually reset the sensor each time you refuel the vehicle. This is achieved by issuing a PWM signal to the sensor.
To set that mode, you need to set the Auto Reset setting to OFF in
the FLOW.txt sensor settings file.
For more information, read the sensor manual.
B: Forget consumed volume
Under this mode, the consumed fuel volume will reset after each power cycle. This is especially important for fuel-powered vehicles, as there is no equivalent of a voltage reading to initialize the remaining energy percentage.
On the upside, you do not need to wire a PWM signal to the sensor to reset the consumed volume measurement. You will have to update the starting volume manually.
To set that mode, you need to set the Auto Reset setting to Power ON in
the FLOW.txt sensor settings file.
For more information, read the sensor manual.
Sensor configuration
Calibrate the flow meter according to the manufacturer instructions.
Additionally, configure the sensor to report the consumed fuel volume, by
setting the FUEL display to consumed in FLOW.txt.
Script parameter settings
Once this is done, perform the following steps.
- Place this script in the "scripts" directory of the autopilot.
- Connect the sensor to a serial port (for now referred to as
SERIAL*) - Enable the scripting engine via
SCR_ENABLE. - Set the baud rate to 19200 with
SERIAL*_BAUD = 19. - Set port protocol to scripting with
SERIAL*_PROTOCOL = 28. - Point the script to that serial port by configuring
VSPF_PORT. Set it to
0 to select the first scripting serial port, etc...
Then, decide which battery monitor will be assigned to the sensor (for now
referred to as BATT*).
-
Set
BATT*_MONITOR= 29 (Scripting) -
Set
BATT*_CAPACITYto the amount of ml your tank is filled with. This can
vary from flight to flight. If operating under Mode A (Save consumed), you do not need to update this value with what is remaining in the tank after every reboot. If you are operating under Mode B (Reset consumed), you will have to update this value after every reboot, if fuel was consumed in the meantime.
-
Tell the script which battery monitor is employed via
VSPF_BAT_IDX. -
Set the selected operation mode:
For mode A (save consumed), set VSPF_MODE=0.
For mode B (reset consumed), set VSPF_MODE=1.
- Enable the script itself with
VSPF_ENABLE=1.
Operation
Once everything is configured correctly, the corresponding battery monitor
will display in the corresponding BATTERY_STATUS MAVLink message:
- The current fuel flow in cl/hr (centiliters per hour) in the
current_batteryfield. - The current fuel already consumed in ml (milliliters) in the
current_consumedfield.
You can use the parameter VSPF_CFACT to compensate for scaling errors in the
sensor setup. 1 is the default value. Set to <1 if the measurements are too high.
Refueling
When refueling, make sure to set BATT*CAPACITY to the actual, new value of
the fuel volume that is in the tank.
If operating under mode A (Save consumed), reset the sensor by triggering the PWM pulse.
Parameters
The script used the following parameters:
VSPF_ENABLE
Setting this to 1 enables the driver.
VSPF_BAT_IDX
Selects which battery monitor instance will be fed the fuel consumption information. 1-indexed.
VSPF_CFACT
This is multiplicative factor to correct the measured flow. Set to <1 if your sensor measures too high and vice versa.
VSPF_MODE
Tells the script which mode it is operating in. 0: Mode A, save consumption. 1: Mode B, reset consumption.
VSPF_PORT
Which Scripting serial port the sensor is connected at. Set to 0 to select the first serial port, 1 to select the 2nd serial port, etc...
