Also known as an Electronic Volume Corrector (EVC), PTZ Volume Converter, and Gas Volume Correction Device, the Honeywell EK205 is widely used wherever accurate gas billing and custody transfer measurement are required. The EK205 automatically converts measured gas volume into standard reference conditions by continuously calculating pressure and temperature compensation in accordance with EN 12405-1, ensuring highly accurate gas consumption measurement for custody transfer, billing, and industrial process control.
Suitable for installation on Honeywell Elster gas meters as well as gas meters from other leading manufacturers, the Honeywell EK205 supports PTZ, PT, and Temperature (T) Volume Conversion. The device combines advanced volume correction, flexible communication protocols, long-life battery operation, and powerful data logging capabilities, making it an ideal solution for gas utilities, industrial plants, OEM gas skids, commercial facilities, and City Gas Distribution (CGD) networks.
As a leading Honeywell Elster EK205 Volume Converter supplier and distributor in India, Star Gas Service supplies genuine Honeywell Electronic Volume Correctors for industrial, commercial, OEM, EPC, and utility gas projects across India. Our technical experts help customers select the correct configuration based on gas meter type, operating pressure, communication requirements, and application needs while providing competitive pricing, technical consultation, and PAN India delivery.
Manufactured in accordance with MID, EN 12405-1, and ATEX standards, the Honeywell EK205 offers reliable gas volume conversion, advanced event recording, flexible communication interfaces, and long-term operational stability. Its rugged IP65-rated enclosure, optional external power supply, integrated pressure and temperature measurement, and compatibility with SCADA systems make it one of the most reliable Gas Volume Converters available for industrial and commercial gas measurement applications.
The Honeywell Elster EK205 is engineered for applications where accurate gas volume correction, dependable data logging, and seamless communication are essential. Unlike conventional gas measurement systems that record only actual gas volume, the EK205 automatically calculates gas volume at base conditions by continuously compensating for changes in gas pressure and temperature, ensuring highly accurate billing and custody transfer measurement.
Designed for easy installation on gas meters from Honeywell Elster and other manufacturers, the EK205 supports meter mounting, pipe mounting, and wall mounting, offering excellent flexibility for both new installations and retrofit projects. Its integrated lithium battery provides more than five years of maintenance-free operation under standard conditions, while multiple communication protocols allow effortless integration with SCADA systems, Electronic Volume Correctors, Flow Computers, and industrial monitoring platforms.
The Honeywell EK205 also features advanced event recording, extensive archive storage, configurable digital inputs and outputs, and user-friendly operation through its backlit graphical display, making it a trusted solution for industrial gas distribution, commercial gas metering, and utility gas management.
The Honeywell Elster EK205 Volume Converter automatically converts the measured gas volume into standard reference conditions by continuously monitoring gas pressure, gas temperature, and pulse signals received from the connected gas meter. This process ensures highly accurate gas volume calculation for custody transfer, billing, industrial process control, and gas distribution applications.
The EK205 receives flow-proportional pulse inputs from compatible gas meters while simultaneously measuring gas pressure through an integrated capacitive ceramic pressure sensor and gas temperature using a high-precision Pt-500 resistance temperature sensor. Based on these measured values, the device calculates the corrected gas volume in accordance with EN 12405-1, applying approved compressibility calculation methods such as AGA NX-19, AGA 8, AGA 8 DC-92, and S-GERG 88.
In addition to gas volume correction, the EK205 continuously records operating data, pressure, temperature, alarms, events, and historical measurement information through its advanced data logging system. The integrated communication interfaces and multiple industrial communication protocols allow seamless integration with Electronic Volume Correctors (EVCs), SCADA systems, flow computers, and remote monitoring platforms, enabling efficient gas management and automated data collection across industrial and commercial gas distribution networks.
Its long-life lithium battery, low power consumption, rugged IP65 enclosure, and flexible mounting options ensure reliable performance even in demanding industrial environments with minimal maintenance requirements.
The Honeywell Elster EK205 Volume Converter is designed to deliver highly accurate gas volume conversion while maintaining long-term stability in demanding industrial and commercial environments. Manufactured in accordance with MID and EN 12405-1, the EK205 performs precise PTZ, PT, and Temperature (T) volume conversion for custody transfer, gas billing, industrial process monitoring, and utility gas distribution applications.
