Sounds like a fun project.
It may be a lot easier to make your Flow Meter a ‘Stand-Alone’ unit using a PLC or Arduino or similar to measure the pulse rate then drive a separate digital readout display. You could then have an alarm signal output which would Estop Mach3 and turn off the spindle if the flow rate went below a certain value.
I use a water flow sensor and temperature sensor with my laser, I am not really interested in the actual flow rate as if the flow stops it operates the Mach3 Estop and if the water temp. exceeds a pre-set limit again it operates Estop.
I don’t have to visually monitor anything as the system will operate automatically and over the last 11 Years it has behaved perfectly.
