In compliance with the latest international standards for fiscal flow measurement system, the AuditFlow Flow Measurement System fully meets the functionalities of an Electronic Measurement System. That is, in addition to performing flow correction calculations in real time, it has data security features, traceability, diagnostics and procedures in case of failure in compliance with such standards.

The HFC302 module, the flow computer of the AuditFlow Flow Measurement System, is fully configurable and designed with the most advanced hardware and software to monitor, correct and control liquid and gas flows.
