Who should perform repairs when a Smith meter requires major maintenance?

Major maintenance on a Smith meter should be performed by the manufacturer because they have the specialized knowledge, tools, and access to original parts necessary to ensure the meter operates accurately and effectively after repairs. Manufacturers typically provide detailed technical instructions and standards for maintenance, which are critical for maintaining the equipment's calibration and reliability. This expertise is essential, especially considering that improper repairs could lead to measurement inaccuracies, potentially resulting in financial loss or safety hazards.

While refueling maintenance shops or liquid fuels maintenance shops may handle routine maintenance or minor repairs, they generally do not possess the specific technical resources or manufacturer training required for significant overhauls. The department of weights and measurement is involved in ensuring measurement standards but does not perform repairs. Thus, the manufacturer is best qualified for this specific task.
