Endress+Hauser FLOWSIC Ultrasonic Gas Flowmeters

Provides accurate and reliable measurement of natural gas and industrial gases for both process monitoring and custody transfer applications. Using ultrasonic transit-time technology, these instruments measure volumetric flow, gas velocity, and speed of sound without moving parts. The portfolio covers distribution networks, high-pressure transmission pipelines, hydrogen blending, and industrial gas processes.

Product Overview

The FLOWSIC portfolio includes models for non-custody transfer monitoring, upstream gas measurement, distribution metering, and fiscal custody transfer.

Available models include:

• FLOWSIC300 – Non-custody transfer measurement and process monitoring
• FLOWSIC600 – Reliable flowmeter for industrial process applications
• FLOWSIC600 DRU-S – Robust upstream gas measurement
• FLOWSIC500 – Custody transfer for natural gas distribution
• FLOWSIC550 – High-pressure distribution gas flowmeter
• FLOWSIC600-XT – Custody transfer natural gas measurement with advanced diagnostics

These systems are designed for inline installation in pipelines and integrate with flow computers and automation systems.
