What makes FLOWSIC600-2plex different from a standard 4-path meter?

The 2plex variant uses a 4+1 configuration, combining a custody transfer gas flowmeter with an additional independent control measurement path in one compact meter body.

Where is the 2plex variant suitable?

It is suitable for custody transfer natural gas metering applications where operators need reliable measurement, compact installation and enhanced diagnostic visibility.

What should be checked before selecting this meter?

Review the custody transfer requirement, pipe size, gas composition, operating pressure, temperature, hazardous area approval, communication requirement and project metering standards.

Which communication option is listed on the current OEM product page?

The current product page lists Modbus TCP as the digital communication option.

Does the product support continued measurement during a power failure?

Yes. PowerIn Technology supports continuous measurement operation for up to three weeks in the event of mains voltage failure, according to the current OEM product information.

FLOWSIC600- XT 2plex

Q: Can it measure natural gas with hydrogen content?

Yes. The FLOWSIC600-XT product family supports natural gas measurement with up to 30% hydrogen.

Ultrasonic Gas Flow Meter

FLOWSIC600-XT 2plex is designed for custody transfer natural gas metering applications where the main flow measurement needs an additional independent control measurement path within a compact meter body. The 4+1 path configuration combines a custody-transfer gas flowmeter with a control measurement device, supporting advanced diagnostics without requiring a separate meter installation. In gas transmission, storage, processing, onshore, offshore and metering skid applications across the UAE, the 2plex variant supports reliable flow measurement with added diagnostic visibility in a compact device configuration. The product family supports natural gas measurement, including natural gas with up to 30% hydrogen, and is available for a wide range of operating conditions. The device supports intelligent application diagnostics through i-diagnostics and includes PowerIn Technology for continued measurement operation during mains voltage failure. Selection should consider the custody transfer requirement, pipe size, gas composition, pressure, temperature, hazardous area approval, flow computer integration and project approvals. Emphor IPS can support UAE customers with product selection and enquiry coordination based on project requirements.
