IV. Working Principle

FloBoss S600+ Prover system realizes simultaneous daily pipeline metering and periodic meter verification based on core logic of synchronous prover pulse acquisition + high-precision 64-bit error calculation + automatic sequence interlock control.

After 24VDC power supply startup, the unit completes full-channel hardware self-test covering CPU memory, prover pulse circuit, valve output and communication bus. Passed self-test enters standby metering mode, continuously collect meter pulses and temperature/pressure/density transmitter signals to compute fiscal flow and accumulate totals in real time.

When calibration task is triggered, CPU sends instructions to P154 prover module to switch calibration valves via relay outputs, synchronously capture standard prover switch trigger pulses and meter measurement pulses. The module independently record dual pulse timing and real-time medium conditions, upload pulse difference and process parameters to main control unit after preset calibration cycles are finished.

Main control unit calculate volume correction, K-factor, indication error and repeatability based on API/AGA standards, auto save complete calibration records into triple redundant memory; lock corresponding stream custody transfer during calibration, auto switch back to normal fiscal metering after verification finished. All calibration events, operator accounts and fault information are written into audit logs, retrievable locally or remotely uploaded to station monitoring system.
