If an accumulator loses air pressure there will be
- rapid fluctuations of instruments.
- rapid depressurisation of system.
- pump cavitation.
Explanation
The accumulator's gas charge cushions pressure surges; if it loses its air charge it can no longer damp the pulsations from the pump and services, so pressure instruments fluctuate rapidly. The system does not immediately depressurise because the pump still maintains pressure, and the loss does not directly cause inlet cavitation.

Accumulators in instruments?? pfcu's maybe?
