Endress+Hauser Proline Prosonic Flow G 300 Ultrasonic Gas Flowmeter

The Endress+Hauser Proline Prosonic Flow G 300 is an industrial ultrasonic gas flowmeter designed for reliable and accurate measurement of natural gas and other process gases. It uses the transit-time ultrasonic measurement principle to determine gas flow without mechanical moving parts, making it suitable for continuous operation in demanding industrial environments.

Prosonic Flow G 300 combines a robust sensor design with the Proline 300 transmitter, providing reliable flow measurement together with advanced diagnostics, digital communication and convenient device configuration.

Ultrasonic Measurement for Natural and Process Gas

Prosonic Flow G 300 is designed specifically for gas flow measurement and can be used for natural gas and a variety of industrial process gases.

The ultrasonic measuring principle determines flow velocity by comparing the transit time of ultrasonic signals traveling with and against the direction of flow. Because the measurement system has no moving mechanical parts, it avoids mechanical wear and can provide stable long-term operation with low maintenance requirements.

Accurate Gas Flow Measurement

The Prosonic Flow G 300 provides reliable measurement across a wide range of operating conditions. Its ultrasonic technology allows accurate measurement of gas flow while maintaining a relatively low pressure loss through the measuring system.

The instrument can provide mass flow, volume flow and corrected volume flow, depending on the selected configuration and process parameters. This makes it suitable for both process monitoring and gas flow control applications.

Wide Range of Industrial Gas Applications

The flowmeter can be applied to different gas measurement tasks in industrial plants, including natural gas measurement, process gas monitoring, gas distribution and combustion-related applications.

Its robust construction makes it suitable for applications where reliable gas measurement is required under changing process conditions.

Robust Sensor and Transmitter Design

The Prosonic Flow G 300 combines the gas flow sensor with the Proline 300 transmitter. The transmitter provides access to measurement values, device configuration and diagnostic information while supporting integration into modern plant automation systems.

The instrument is designed for demanding industrial environments and provides a robust solution for continuous gas flow measurement.

Advanced Diagnostics and Heartbeat Technology

Prosonic Flow G 300 incorporates Endress+Hauser Heartbeat Technology, providing integrated diagnostic and verification functions.

Heartbeat Technology can help users monitor instrument condition and verify measurement performance without removing the flowmeter from the process. This supports predictive maintenance strategies and can help reduce unnecessary service work and process interruptions.

Digital Communication and Device Integration

The Proline 300 transmitter supports modern digital communication and plant integration. Users can access measurement values, configuration parameters and diagnostic information through the transmitter interface and available digital communication technologies.

An integrated web server provides convenient browser-based access to the device, simplifying commissioning, configuration and troubleshooting.

No Mechanical Moving Parts

Unlike mechanical gas flowmeters, Prosonic Flow G 300 uses ultrasonic sensors rather than rotating or moving measurement components. This eliminates mechanical wear within the measurement principle and contributes to reduced maintenance requirements.

The absence of moving parts also makes ultrasonic measurement attractive for continuous industrial gas applications where long-term reliability is important.
