GasMicro™ Electronic Volume Corrector

Name: GasMicro Electronic Volume Corrector – Brochure & Quote
Brand: Galvanic

Description

Overview

The GasMicro™ Electronic Volume Corrector is a three-in-one measurement device that calculates the corrected volume of natural gas according to AGA7 and AGA8 standards. Whether operators are on the sending or receiving end of a natural gas distribution system, they need assurance that the actual value of transported gas is assessed correctly—which requires not only precise Btu content measurement, but also accurate determination of the actual volume of gas delivered, corrected for temperature and pressure, something a turbine or rotary flow meter alone cannot provide.

Working closely with plant engineers in the region, Seven Star LLC proudly offers the GasMicro™ to natural gas distribution operators, custody transfer stations, and pipeline measurement facilities across the Sultanate of Oman, Muscat, and the wider GCC. As one of the most economical electronic volume correctors on the market, the GasMicro™ delivers dependable, field-proven measurement value for gas transmission and distribution networks.

Measurement Principle

The GasMicro™ is ideal for both remote-mount and instrument-mount applications. In remote-mount configurations, the turbine or rotary meter sends an electronic signal to the GasMicro instrument representing the volume of gas measured, and the GasMicro then calculates the corrected volume. In instrument-mount configurations, Galvanic’s instrument is mounted directly to the turbine or rotary gas meter through a mechanical instrument drive, generating the electrical signal representing measured gas volume before calculating the corrected value.

In both scenarios, the GasMicro device logs and stores the resulting data in memory for record keeping and ultimately for data distribution. At 25°C, the GasMicro delivers corrected volume accuracy of ±0.05% of reading, pressure accuracy of ±0.05% of reading, and temperature accuracy of ±0.14°C, maintaining ±0.2% accuracy across its full -40°C to 65°C operating range.

Engineering Design of the GasMicro™

The GasMicro™ provides user-friendly GasMicro IMACS® Windows® PC software with point-and-click/drag-and-drop functionality for easy local or remote configuration. Fully configurable Modbus (Enron RTU) communication with three levels of password protection ensures secure, flexible data access and system integration.

Automated options include automated meter reading and reporting, plus configurable alarms capable of initiating automatic dial-out alarm or email notifications. A key reliability feature is the device’s redundant mechanical backup measurement, ensuring continuous measurement even in the event of electronic failure—a critical safeguard for custody transfer applications where measurement continuity carries significant commercial and contractual weight.

Why Choose Seven Star LLC for Legacy GasMicro Support

Many custody transfer stations across Oman still operate on the original GasMicro platform with its proven redundant mechanical backup measurement, and continuity of supply for these units matters as much as new deployments. Seven Star LLC maintains direct sourcing channels with Galvanic Applied Sciences for both new GasMicro units and replacement components, helping operators avoid unplanned measurement gaps on custody transfer meters where continuity carries real contractual weight.

With engineering support in Muscat, we also help distribution operators plan the Modbus (Enron RTU) integration and password-protection configuration for new GasMicro installations, and can advise on whether an existing site would benefit from stepping up to the GasMicro NG’s cellular connectivity when the time comes to upgrade in Oman and the wider GCC, and can advise on battery replacement scheduling to keep the 4-year D-cell power supply from lapsing unexpectedly.

About brand

Hydrogen sulfide measurement in natural gas is where Galvanic Applied Sciences built its name, and its lead acetate tape analyzers are written into many gas quality specifications. The company was founded in 1975 and is based in Calgary, Canada. Seven Star LLC sources and supplies Galvanic process analyzers for gas and liquid streams, together with their consumables and spare parts, for operators in Oman, working from the analyzer model, serial number and application data.

Galvanic analyzer families listed here

Galvanic analyzers on this page fall into three groups:

Sulfur and gas quality: ProTech903 and ProTech 1000 Z2 tape-based H2S and total sulfur analyzers, the AccuLase-GPA tunable diode laser analyzer for H2S, CO2 and H2O, and AccuChrome gas chromatographs for heating value and composition
Sulfur recovery: Brimstone analyzer systems and the 943-TGX tail gas analyzer
Liquids and photometry: Monitek turbidity, suspended solids and color monitors, Monitek Ultrasonic oil-in-water monitors, the AccuSeries-LPA wet chemistry analyzer, the Viscosite in-line viscometer and FPA 4100 UV photometers

GasMicro and GasMicro NG electronic volume correctors complete the list.

Where Galvanic analyzers are used

The manufacturer names natural gas processing, pipelines and distribution, refining and oil production, chemical and petrochemical production, power and biogas, water and wastewater, and food and beverage as its markets. In the GCC the common duties are H2S and total sulfur at sales gas and custody transfer points, tail gas control on Claus sulfur recovery units, heating value measurement, and oil-in-water monitoring of produced water.

Ordering Galvanic analyzers and parts: what we need

For a new Galvanic H2S analyzer or chromatograph, send the stream composition, the component and range to be measured, sample pressure and temperature, the number of streams, area classification, power supply and the outputs required. For consumables and spares such as sensing tape, lamps, columns or pump parts, send the analyzer model and serial number and the part number from the manual. Manuals differ by generation, so a nameplate photo helps us check the item against the manufacturer's documentation.
