Hi everyone.
I need some advice for a system I am developing.
Basically I am looking to control an air pump (as it is for pumping a flammable liquid) that will use an air regulator valve to control the amount of air flow into the pump, thus varying the speed of the pump.
The fluid I am pumping will have an inline flow meter that will inform a PIC how fast it is being pumped. With the knowledge of how fast the pump is running I will be able to vary the air regulator to speed up or slow down the pump.
Does anyone know what type of air regulator I will need to allow me to vary to air flow?
i.e. Do air regulators require a variable voltage to determine how open or closed it should be or do they respond to a series of digital input data bits?
Thank you for your time,
Robert Hurd
