Meter seals are security devices used to protect utility meters, such as electricity, water and gas meters, from tampering or unauthorized access. These seals are typically made of plastic or metal and are designed to be securely attached to the meter, making it difficult to remove without leaving evidence of tampering. Meter seals help ensure the accuracy and integrity of meter readings, preventing fraud and unauthorized usage. They are commonly used by utility companies and regulatory agencies to maintain the security of metering systems.
