How Often Should Flow Meters Be Calibrated?
There is no single calibration interval suitable for every flow meter.
The appropriate calibration frequency may depend on:
- Flow-meter technology
- Fluid
- Flow range
- Frequency of use
- Operating conditions
- Required measurement accuracy
- Manufacturer recommendations
- Previous calibration history

- Instrument stability
- Internal quality procedures
- Customer or regulatory requirements
Organizations should establish calibration intervals according to their quality-management system and measurement history.
What Happens If a Flow Meter Fails Calibration?
If a flow meter does not meet its applicable acceptance criteria, the organization should evaluate the measurement impact.
Depending on the situation, actions may include:
- Adjustment
