The Importance of Lead Seals
Reason for Lead Seals:
1.Tamper Prevention
Prevents unauthorized access: The seal acts as a physical barrier to stop users from:
Manipulating meter readings (e.g., slowing down or stopping the meter).
Stealing utilities (e.g., illegal wiring, pipe bypassing).
Protects internal mechanisms: Prevents damage from improper handling by untrained individuals.

2.Ensures Fair Billing & Accuracy
Guarantees reliable measurements: The seal certifies that the meter was:
Properly calibrated and verified by authorities.
Not altered after installation.
Legal evidence: A broken seal indicates potential tampering, serving as proof for investigations.
3.Safety & Risk Mitigation
Gas meters: Unauthorized opening may cause gas leaks, leading to explosions or poisoning.
Electricity meters: Tampering can result in short circuits, fires, or electrocution.
Water meters: Illegal modifications may cause leaks or contamination risks.
4.Legal & Regulatory Compliance
China’s laws: The Metrology Law and Electricity Law mandate sealing utility meters.
Global practice: Many countries (e.g., US, EU) require similar anti-tampering seals (plastic/metal/electronic).
Consequences of breaking seals: Fines, service termination, or legal action.

Types of Seals
Materials: Traditional lead seals, plastic seals, RFID-enabled electronic seals.
Identification: Unique serial numbers, QR codes, or company logos for tracking.
