Proline Prosonic Flow 9G3B G 300 ultrasonic flowmeter G300 

What is Proline Prosonic Flow G 300

• It’s an ultrasonic transit-time flowmeter for gases — natural gas, processed gas, biogas, or other industrial gas mixtures.
• The unit directly measures gas volume flow, pressure and temperature, enabling real-time, corrected flow readings.
• It supports user-defined gas mixtures (up to 8 components), which means it can be adapted to custom gas compositions in process environments.

Key Specifications & Performance

What Makes It Stand Out — Features & Advantages

• Insensitive to gas composition: The ultrasonic measuring principle remains accurate even if the gas mixture changes significantly.
• Handles wet or condensate-laden gas: The sensor design is robust against condensates — making the unit reliable even for “wet gas” applications.
• Multivariable measurement (flow + pressure + temperature): Allows real-time compensation and more accurate volumetric flow readings under different operating conditions — critical for process control.
• Flexible integration & diagnostics: Compact transmitter and configurable I/O make it easier to integrate into existing systems; built-in diagnostics and self-verification via the manufacturer’s “Heartbeat Technology.”
• High turndown ratio (> 133:1): Enables accurate measurement across a wide flow range (from low flow to high flow) with one device.

Typical Use Cases / Industries

• Natural gas pipelines and distribution networks
• Process gas measurement in oil & gas production, refineries, petrochemical plants
• Measurement of mixed, processed, or biogas in chemical/energy plants
• Situations with changing gas composition or wet / condensate-laden gas where reliability and measurement stability are required

Why Engineers / Industry Use It

Because of its accuracy, flexibility, and robustness, the Prosonic Flow G 300 is often selected where precise, reliable gas flow measurement is critical, especially under challenging conditions (e.g. varying gas composition, humidity, pressure/temperature swings, industrial processes). Its ability to simultaneously measure flow, pressure, and temperature — and compensate accordingly — helps ensure consistent, correct data for process control, billing, safety systems, or regulatory compliance.
