FAQ

Standard practice is annual calibration, but actual frequency may depend on usage, application, and internal quality requirements. High-precision or regulatory uses may require semi-annual or even quarterly calibration.

You should calibrate the meter if you notice unreliable readings, changes in flow consistency, difficulty in zeroing the device, after maintenance or repair, or after any suspected damage. Regular scheduled calibration should also be based on company policy, process requirements, or quality standards. Some industries require maintaining a calibration certificate within a defined interval.
