Can flow meter verification move from a fixed interval to a condition-based check?

Partly: part of the task converts to a condition and part stays on the calendar. Process meters convert to diagnostic verification; custody transfer and billing meters keep the interval set by legal metrology or the contract.

What condition would trigger flow meter verification instead of the calendar?

Meter diagnostics reporting a health flag (electromagnetic and Coriolis meters self-verify), or a mass balance across the meter deviating by more than the tolerance

What reading proves flow meter verification was done?

Meter diagnostic verification result, mass or volume balance deviation. Observed by: In-situ verification tool or the meter's own diagnostics; comparison against a reference meter for custody transfer.

What evidence does flow meter verification produce for an ISO 55001 or ISO 45001 audit?

Verification report per meter with the diagnostic result and, for billing meters, the proving certificate

Flow meter verification

Modern meters check themselves. The one that decides an invoice still gets proven on the interval the contract or the regulator says.

Condition that replaces the interval: Meter diagnostics reporting a health flag (electromagnetic and Coriolis meters self-verify), or a mass balance across the meter deviating by more than the tolerance
Reading that proves it: Meter diagnostic verification result, mass or volume balance deviation
Why the interval stays: Process meters convert to diagnostic verification; custody transfer and billing meters keep the interval set by legal metrology or the contract.
Evidence an auditor accepts: Verification report per meter with the diagnostic result and, for billing meters, the proving certificate
First move: Run the in-situ verification on every electromagnetic meter on the list; it takes minutes and replaces the annual removal.
