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.
