Whoa, slow down, I take it you are under a bit of pressure on this 1!! Can you tell me/us(other members) what signal is output from these sensors? Are do they pulse a set amount of times every set amount of fluid, or are they voltage based?
How does the system work at the moment? Do you already have a wired system that reads these sensors? If so then there may be an easy way to impliment the radio part.
Give us a bit more info to get us excited :wink:
re-edit... ok I just read that they are voltage based (I need to slow down 2!) what voltage are they 0-5 0-10 ac/dc???
