4. How Meter Seals Work

Meter seals function by locking the meter’s access points, making any unauthorized attempt at opening immediately visible. They often feature unique serial numbers, barcodes, or RFID technology to track and verify authenticity. If a seal is broken or missing, it serves as a clear indication of tampering.
