GasMicro NG™ Electronic Volume Corrector

Overview

The GasMicro NG™ Electronic Volume Corrector is the next-generation device developed by Galvanic Applied Sciences, building upon the success of the original GasMicro meter with a range of new features and capabilities that make it an even more reliable and versatile choice for the natural gas measurement market. Whether operators are on the sending or receiving end of a natural gas distribution system, precise volume correction for temperature and pressure is essential to accurately assess the value of transported gas—something a turbine or rotary flow meter alone cannot provide.

As an authorized supplier of Galvanic instrumentation, Seven Star LLC proudly offers the GasMicro NG™ to natural gas transmission operators, custody transfer stations, and pipeline measurement facilities across the Sultanate of Oman, Muscat, and the wider GCC. Its combination of high-accuracy sensing and modern remote connectivity supports the region’s transition toward digitally connected gas measurement infrastructure.

Measurement Principle

The GasMicro NG™ features integral smart plug-and-play pressure transducers with ±0.05% of reading accuracy and a PT1000 temperature sensor with ±0.15% of reading accuracy. These highly accurate pressure and temperature measurements, combined with advanced reverse flow and rocking detection algorithms, provide superior meter correction accuracy compared with legacy volume correctors.

The device supports multiple meter types including turbine, rotary, and diaphragm, and accommodates both low-frequency and high-frequency pulse inputs, giving it broad compatibility across existing metering infrastructure. This versatile integration capability means the GasMicro NG™ can be retrofitted onto a wide range of existing gas meters without requiring a complete metering system replacement.

Engineering Design of the GasMicro NG™

The GasMicro NG™ features advanced electronics enabling remote monitoring and control capabilities, with modern 4G communication and 3G fallback capability allowing users to monitor gas measurement data in real time from any location via a web-based structure. Multi-client/server TCP connections support flexible operation with remote diagnostics, configuration, and data acquisition.

The device is offered in three tiers—CORE, PRO, and FLOW—each building on the previous level’s capabilities. The CORE tier provides single-stream PTZ volume correction with a 10-year battery life, while the PRO tier adds Cat 4 wireless modem connectivity, Modbus TCP, and AGA7 meter correction. The FLOW tier adds high-frequency pulse input, AGA5 energy and mass calculation, and ISO6976 heating value calculation for comprehensive gas measurement applications.

Key Features

The GasMicro NG™ combines precision volume correction with comprehensive remote connectivity. Core capabilities include:

• Smart plug-and-play pressure transducers with ±0.05% of reading accuracy.
• PT1000 temperature sensor with ±0.15% of reading accuracy.
• Advanced reverse flow and rocking detection algorithms for superior correction accuracy.
• Integrated quad-band, low-power 4G modem with 3G fallback on secure communication protocols.
• Supports multiple meter types (turbine, rotary, diaphragm) with low/high-frequency pulse inputs.
• Up to 10-year battery life on CORE tier configurations.
• Rugged IP67 enclosure, outdoor rated and UV resistant, with lithium batteries rated to -40°C.
• Compliant with AER Directive 017, API MPMS Chapter 21, AGA5, AGA7, AGA8, and AGA NX-19.

Industrial Applications

The GasMicro NG™ is well suited to natural gas transmission and distribution networks, custody transfer metering stations, and pipeline measurement facilities across Oman that require precise, remotely monitored volume correction. Its hazardous area certifications (Class I Div 1 & 2, Groups ABCD, T3) make it suitable for deployment at wellhead and gathering station metering points across the region’s upstream and midstream gas infrastructure.

As an authorized supplier of Galvanic instrumentation, Seven Star LLC supports natural gas transmission operators, custody transfer stations, and pipeline measurement facilities throughout the Sohar and Salalah economic zones and the broader GCC region with the GasMicro NG™’s advanced volume correction capabilities.
