How to log the duty cycle of the valve in flow meter?

The main aim of flow montoring is to detect flow anormalies rather to inform absolute flow. The SC allows users to normalise the flow across the 8 bars of display.

It works like a temperature gauge or tank level gauge on a dash board. The actual cc/min is not the primary objective. That said, Jeff suggested calibrating the sensor to display absolute flow if you want to construct your own failsafe strategy on your ECU.

It is posssible to extract the raw signal from the sensor pulse/sec and make your own "frequancy to voltage" decoder for your logger. This way you can have both.
