Exactly, I want a digital pressure gauge for my control system.
I suppose I could also measure flow rather than pressure. They will be related during normal operation.
The idea is to use the flow measurement to adjust the motor drive, helping to provide a consistent and repeatable flow. Plus some more checks that your system is working.
I don't want to add anymore mechanical gauges to my car. Everything will feed into the engine control module and used for the control loops.
There will be a single LCD that will display status and measurements, if I want to look at them...
So, what about using an oil pressure sensor? They are cheap... $30 or so. Can anyone find specs on them? What operating range range they have?
