What happens if the DMA flow meter malfunctions? Could the pressure go dangerously high or could the flow into the DMA be cut off?

As soon as the flow meter begins to malfunction, the watchdog puts the system into safe mode i.e. P2 is set to a fixed, safe pressure and an alarm is sent out. Flow meter malfunctions can be picked up in two different ways by the controller. Firstly, it can recognise unusual or erratic readings and secondly it can compare the flow meter readings with independent flow measurements through the PRV.
