PRE-ENGINEERED NATURAL GAS ANALYSIS
The HGC303 offers pre-engineered analysis and calculations
for natural gas monitoring, eliminating the need for any
further programming and application work. Hooking up gas
connections, power and communications cables is all that is
required to get this plug and play transmitter ready to work.
The HGC303 provides a full 11-component C6+
analysis on natural gas with a 300-second cycle time and a
repeatability of 0.05% Heating Value. The HGC calculates
and digitally transmits 20 gas parameters according to GPA
or ISO Standard, including Upper and Lower Heating Values,
Wobbe Index, Specific Gravity, Compressibility and Specific
Heat Ratio.
LOW COST OF OWNERSHIP
Low analyzer price, easy installation, low maintenance and reliable performance contribute to time
and cost savings and a low overall cost of ownership.
LOW MAINTENANCE
The HGC303 is designed to perform reliably in natural gas applications ranging from remote
wellheads to gas processing plants, gas transmission and distribution points and endusers. The
HGC’s small and light-weight design facilitates a simple swap-out of the entire analyzer in minutes,
rather than requiring cumbersome maintenance in the field.

SMALL SIZE FOR EASY FIELD INSTALLATION
The HGC303 is engineered to take full advantage of
Yamatake Corporation’s leading sensing and control
technology, packing into the compact design of a
9.6” tall field transmitter the features, functionality and
performance of a full sized chromatograph. Intrinsic
safety and weatherproof design allow installation at the
pipeline without additional sheltering.
EASY TO USE WINDOWS™ BASED SOFTWARE
The HGC can communicate with a PC via the HFA
Fieldbus/USB converter. Windows®* based software
(HGM) provides an easy-to-use interface for viewing data
and diagnostic information and to perform instrument set-
up functions. In particular, the HGM software:
• Stores 300 chromatograms
• Trends BTU values
• Trends carrier gas pressure and oven temperature
• Stores raw and calculated data values
• Indicates operational status and diagnostic values
• Allows instrument set-up in a convenient environment*The HGM software requires Windows® 98,Windows® Me, Windows® 2000, Windows® NT.
DIGITAL COMMUNICATIONS
The HGC303 communicates via Foundation Fieldbus™ protocol with
external devices and can be connected to a PC via a Fieldbus™/
USB adapter (Model HFA).
The HGC can be integrated with existing SCADA systems via a
companion device, the HDM Data Manager. The HDM is a Class I Div
2, field-mountable converter that offers MODBUS communications
as well as a total of three additional digital or analog outputs (RS-
232, RS-422, RS-485; 4-20 mA).
The Yamatake HGC303 BTU Gas Chromatograph and MODBUS
Interface have been tested for compatibility with the leading
manufacturers of flow computers insuring seamless integration into
your gas metering system.
NATURAL GAS SAMPLING SYSTEM
The HGC is available with a modular sample conditioning
system, assuring a cost effective, application specific
solution for a reliable delivery of a clean and dry sample,
even under the most adverse conditions. The sample
system provides connections and functionality for automatic
calibration. Optionally available is the integration of a
moisture measurement using a Xentaur HTF™ moisture
sensor and transmitter.
