Hi Jarvis,
Take a look at the order form/price list on our home page for the list of available sensors. Note that today we are not compatible with many sensors outside of the ones we provide, and it is not trivial for us to add a new sensor type due to the in depth characterizations we do of every sensor we support. In time, we will add more support for additional sensor types.
In particular installation, we don't have the ability to add additional temperature sensors arbitrarily, so instrumenting your PSRU would not be trivial. Fuel flow may be compatible if it outputs a current pulse signal like the FloScan units we sell do. Finally, we CAN work with capacitive fuel senders... however, they need to have a voltage level output to work with our EMS.
