Everyone keeps telling me how simple this is yet I don't have a good idea yet.
Scope: Write a pump cavitation alarm. inputs: pump running, pressure transducer.
Right now I have a tmr that says that the pump has been running for time (need to run long enough to build up pressure).
That timer done is a condition for the second timer (pmp alarm tmr) along with the (pressure <= alarm pressure sp).
The idea is that since the customer has had so many problems with different low level sensors, we thought we could monitor pressure as a way to know if we ran out of water in the tank as a means of protecting the pump.
