According to current international standards for custody transfer flow measurement systems, AuditFlow provides a comprehensive solution in a Flow Measurement System. In addition to calculating flow corrections in real time, it has data security, audit trail, diagnosis and procedure in case of failure according to such standards.
The flow computer module HFC302 in the AuditFlow is fully configurable and designed based on leading edge technology in hardware and software to measure and control corrected flow rate of liquid and gas.
