How long should the meter being tested remain in the proving room for temperature equalization with the prover?

• A. 8 hours
• B. 12 hours
• C. 16 hours
• D. 24 hours

Answer: (C)

The recommended duration for allowing the meter being tested to remain in the proving room for temperature equalization with the prover is 16 hours. This time frame is essential to ensure that both the meter and the prover reach thermal equilibrium, which is crucial for accurate measurement. If the temperature of the meter and prover are not aligned, variations in the fluid's density and the meter's internal components might lead to errors in the measurement, affecting the calibration process and results. In practical applications, allowing a period of 16 hours facilitates sufficient time for both instruments to acclimatize to the proving room's environmental conditions and mitigate any thermal discrepancies. This approach enhances the precision and reliability of the measurement verification process.
