Features of IC card prepayment system:

It is suitable for a wide range of flow meters.

Automatic conversion of flow unit and automatic calculation of flow coefficient of differential pressure flowmeter.

Trade settlement function: enables agreement settlement for high / low traffic.

Emergency fault tolerance function: when the temperature and pressure signal are abnormal, the emergency parameter value is used for compensation calculation.

Debugging calculation function: support to view the original value of each transmitter / sensor signal; support to view various intermediate parameters such as density, enthalpy, etc. in the flow heat energy calculation.

Audit record: power failure record.

Alarm list: it supports recording instantaneous or cumulative alarm information such as flow, heat, temperature, pressure, differential pressure / frequency / volume.

Cumulative report: it supports cumulative flow, daily heat energy report, monthly report and annual report.

Communication function: Standard Modbus RTU protocol, supporting RS485 and RS232C communication interfaces.

Transmission function: support standard current transmission output, signal source channel is optional.

IC card recharging: it supports direct card swiping of instrument without external card reader
