FuelSensor für Tankstation - Tankstelle mit in Anzeige!!

Hello Tero,
I would also like to have a shutdown overpressure because I use bag tanks and I think the filling on time not sure enough. Or maybe a proper volume measurement. Would perhaps be nice to have a volume measurement when defuelling to know how much fuel is still left.

Best regards
Alex

Hello Terros,
you may also be able to give us your order list at the risk that it will not work with the components. That would not be a problem for me

Preliminary order-list (Order with own responsibility, parts may change!)

- Motor-driver: www.ebay.com/itm/5-27V-5A-DC-Motor-Drive...e-J3L2-/292116345085 ?
- Rotary-encoder: www.ebay.com/itm/1PCS-KY-040-Rotary-Enco...uino-CA/141975888668 ?
- ACS712 current-sensor (Option: ACS712 5A#2): www.ebay.com/itm/5-20-30A-ACS712-GY712-Z...Arduino/282838150737 ?
- 1.5" OLED-screen: www.ebay.com/itm/1-5inch-OLED-Display-Mo...o-STM32/253421173636 ?
- Relay-board for main etc (Option 4 CH With Optocoupler): www.ebay.com/itm/5V-1-2-4-6-8-Channel-Re...ARM-AVR/401237960337 ?
- Arduino Pro Mini 5V 16Mhz (Might be a Nano or Duo, let's see)

Pump: xtcm.evojets.de/product_info.php?products_id=39

Some questions still remain but this will move on when all these have arrived. (The screen is coooooool....)

NOTE: Parts may change before prototype is built! Do not blame me if you have ordered some parts that will not me used or if some parts are missing in this list!

I think i will trim the needed hardware down a bit to keep the cost low. Commercial units are available from 169€ so we need to be well under that. I have not found a suitable pressure-sensor yet so initial test's will be done with pump-current when all parts are here. If that can be made fast enough it will work with bags too but that needs to be tested. The key is reaction-speed in shutting down the pump when resistance in pumping changes. This is something that simply just have to be tested. There's not that much info on these things out there so testing is the key. (If you find any links / pictures / parts used in other similar projects let me know!)

Usability should be pretty great with the rotary-encoder and display

This is the best part in every project, brainstorming the functions

Hello Tero,
where did you see commercially offered filling stations for 169 €?
I did not see any under 299 €.
Or do you mean the normal filling stations without display and without indication of the filling quantity?

Alex

Hello Teros

AutoFill vspeak costs 320 euros, because we are sure we will not go. I got everything from the list except for the pump because it was not meant for gasoline or Metahnol. Do you still have a pump for gas? Many Thanks


Hallo Teros

AutoFill vspeak kostet 320 Euro, weil wir sicher sind nicht hingehen werden. habe alles von der Liste bestellt bis auf die Pumpe, weil es nicht für Benzin oder Metahnol gedacht war. Haben Sie noch eine Pumpe für Gas? Vielen Dank

sorry ist doppelt
