Model HGC303 - Heat Value Gas Chromatograph 1-1
Chapter 1 : Introduction
1-1 : Definition of terms
Heat Value Gas Chromatograph (Model HGC303)
The Heat Value Gas Chromatograph measures process gases (N2,
CO2, C1~C6+) that are mainly contained in natural gas, calculates
heat value, density, Wobbe index and compressibility factor, and
converts them into a Fieldbus signal in the field and transmits the
signal to a receiver.
Parameters can all be remotely set, adjusted, and self-diagnosed by
using the HGM.
Measuring and calculating methods comply with ISO 6974 Part 4 and
ISO 6976.
HGC Modbus Interface Unit (Model HMU303)
The model HMU303 Modbus Interface can convert a
Fieldbus signal into a Modbus signal.
Monitoring of such data as heat value can be done using a
Modbus signal as well as a Fieldbus signal.
See the model HMU303 User's manual for more details.
HGC Data Manager (Model HDM303)
Model HDM303 is Modbus interface unit for model HGC303.
Model HDM303 covers all the function of model HMU303.
Model HDM303 also has a powerful functions.
The functions are local display, data storage function, multi
Modbus serial port, multi stream switching, and analog output.
HMU can not be connected together with HDM in the same FB
loop. Only one HMU can be connected in one FB loop with the
HGC. Two or more HDM can be connected in the same FB
loop. For this application, the HDM must be configured first.
Please refer to the model HDM303 User's Manual for more details.
Heat Value Gas Chromatograph Fieldbus Adaptor (Model HFA100)
HFA is an interface used to connect the HGM (HGC
monitor), Windows-based PC application, to
Yamatake’s state of the art analyzer, HGC (Heat value
Gas Chromatograph) that operates on F
OUNDATION
™
fieldbus H1 network. Users are able to configure,
monitor and maintain the HGC all from the PC by
simply connecting the HFA to the Fieldbus network.
