Key tips
- ·Don't extend filter/tubing replacement intervals to save cost - this is an infection-control issue, not just a performance one.
- ·Flow accuracy drift is often the earliest sign of a failing sensor, well before an outright alarm.
Typical Failure Modes
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
Flow calibration drift
HighSymptoms: Delivered flow rate reads off from a known reference.
Root cause: Internal orifice or float-tube wear.
Valve / regulator seal leak
HighSymptoms: Won't hold set pressure, audible gas leak.
Root cause: Diaphragm or seal degradation.
Gauge / dial fault
MediumSymptoms: Stuck, misreading, or broken gauge needle/dial.
Root cause: Mechanical gauge movement wear.
Fitting / connector leak
MediumSymptoms: Gas leak at a hose or cylinder connection.
Root cause: Worn O-ring or damaged threads.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Filter and tubing replacement
- ·Flow accuracy check
- ·Annual full PM
Troubleshooting Approach
A structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Flow calibration drift
- Confirm the presentation - typically delivered flow rate reads off from a known reference.
- Check the most likely cause first: internal orifice or float-tube wear.
- Inspect the affected subsystem against the manufacturer's inspection checklist.
- If the fault is confirmed and not a field adjustment, service or replace the regulator / valve seal kit per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
Symptom: Valve / regulator seal leak
- Confirm the presentation - typically won't hold set pressure, audible gas leak.
- Check the most likely cause first: diaphragm or seal degradation.
- Inspect the affected subsystem against the manufacturer's inspection checklist.
- If the fault is confirmed and not a field adjustment, service or replace the flow tube / orifice assembly per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
