6.4.2Log record access

Due to the Mark III meter’s enhanced log retrieval methods, accessing log records via Modbus communication is not supported. All log records (daily, hourly, audit, alarm, and system) are accessible via Daniel MeterLink (see Section 6.6) when the optional Log Access feature is enabled (see Section 4.1.4).

6.5Optional gas chromatograph interface

The Daniel Mark III Ultrasonic Gas Flow Meter can optionally interface with any Daniel gas chromatograph (GC) that supports the SIM2251 mode to read gas property data (such as for AGA8, AGA10, energy rate, mass rate, and/or JuniorSonic™ profile correction calculations).

The gas chromatograph interface is an optional feature that requires both the Option Board (for Serial Port C) and a valid GC feature key (see Section 4.1.5).

The following table lists the Gas Chromatograph SIM registers polled by the meter. Also refer to Daniel Engineering Specification Part Number ES-17128-005 Rev. B.
