1. Do I need to check the SN code when purchasing a remote flow meter?
To purchase a remote flow meter, I need to check the SN code and determine the severity of the verification based on the procurement scenario.
1. Scenario where the SN code must be verified. 1. Strong inspection of measuring instruments procurement: Remote flow meters listed in the mandatory management of measuring instruments in China, such as water, gas, and heat remote flow meters used for trade settlement, The SN code is the only traceability identifier, which must be verified to be completely consistent with the SN code of the factory inspection certificate, equipment nameplate, and packaging qualification certificate. It is used for subsequent measurement inspection filing and compliance access to public utility systems. 2. Industrial batch matching procurement: for remote flow meters used in automation control systems and IoT platforms, the SN code is the unique identification code of the combustion equipment, which needs to be bound to the management platform to achieve equipment operation and maintenance, fault traceability, and avoid access conflicts. 3. Formal after-sales warranty: When the original factory warranty and spare parts replacement are carried out, the SN code needs to be verified to match the factory file to prevent the purchase of refurbished or counterfeit products.
2. Simplified scenarios for verifying SN codes: 1. Temporary small-scale trial: For small remote flow meters that are not subject to mandatory inspection or long-term operation and maintenance, such as small flow devices used for laboratory temporary testing, only the product type skin manual number needs to be verified to be consistent wit
2. Second hand equipment for short-term leasing or emergency replacement: Used remote flow meters that are only used for temporary emergencies, and only need to confirm that there is no obvious damage to the appearance without mandatory verification of SN codes.
.2. Does the standard orifice plate of steam flow meters used for trade settlement need to be subjected to mandatory inspection?
The measurement method clearly stipulates that flow meters used for trade settlement calculation must be subjected to mandatory inspection and cannot be used without inspection.
3. Do flow meters need to be inspected?
Flow meters need to be inspected, and operators need to pay special attention to measurement accuracy, equipment quality, and scene adaptability.. 1. The reason for the need for acceptance: As a common measuring equipment in industrial and civilian scenarios, the acceptance process of flow meters directly affects the reliability of subsequent use. Authoritative measurement data: In scenarios such as oil and gas trade and pharmaceutical proportioning, a measurement error of 0.1% may lead to economic disputes or quality accidents, and the validity check of calibration certificates must be the core of acceptance. • Equipment lifecycle management: When accepting the new electromagnetic flowmeter, it is necessary to establish equipment files synchronously, including pressure level identification, explosion-proof certification and other parameters. The lack of such technical certificates will directly affect the subsequent annual i
