Standing start/stop of flow sensor using the integral pulse counters.
Standing start/stop of flow sensor using the pulse outputs for external test equipment.
Flying start/stop of flow sensor using the integral counters controlled by external equipment (Sample & Hold).
Flying start/stop of flow sensor using the pulse outputs controlled by external equipment (Sample & Hold).
