Endress+Hauser Unveils Proline Prosonic Flow G 300/500 Ultrasonic Flowmeter

February 21, 2020 by Jacob Ramirez

Endress+Hauser has recently released its new ultrasonic gas flowmeters.

Recently, Endress+Hauser, unveiled what they hope will become the standard of industrial gas measurement. The company’s new product, the Prosonic Flow G 300/500, is a state-of-the-art ultrasonic gas flowmeter, designed to measure numerous types of both raw and processed natural gas, including coal seam gas and biogas, as well as a number of other wet and dry gases.


Endress+Hauser Instrumentation and Proline Prosonic Flowmeters

Endress+Hauser is one of the world’s leading instrumentation and operating process suppliers. The company is family-owned and offers a variety of products and services in industrial automation and measurement; including the measurement of natural and process gas. 

Ultrasonic flowmeters have a number of advantages over their mechanical counterparts. The fact that ultrasonic models measure flow with far fewer moving parts means that they require minimal maintenance, and are much less prone to failure than mechanical flowmeters.

In ultrasonic flowmeters, the external transducer measures the flow of gases using ultrasound, meaning they are often more repeatable and accurate than other types of flowmeters over time. 

As a result, we have Endress+Hauser’s line of industrial-grade ultrasonic flowmeters: the Proline Prosonic Flowmeters, to which the recently unveiled Prosonic Flow G is the newest addition.


The New Prosonic Flow G 300/500

Just like other (gas-oriented) ultrasonic flowmeters, the Prosonic Flow G is able to measure both wet and dry gases via ultrasound. However, Endress+Hauser’s newest model has a number of valuable features for gas instrumentation in demanding industrial settings.

In addition to the reliability inherent to ultrasonic flowmeters, both models of the Flow G include stainless steel components for all wetted areas, in addition to optional titanium replacements for the ultrasound transducers. The sensor housing is also comprised of stainless steel, making the Flow G well-suited to harsh conditions in both on and off-shore natural gas sectors.

Additionally, the Proline Flow G also possesses an optional “extended gas analysis” package, which allows users to use the Flow G in a variety of unique applications, as well as opening up a number of new process controls.This special package offers the ability to calculate new variables based on the type of gas and combinations.

Such variables include volume flow, corrected volume flow, mass flow, energy flow, calorific value, Wobbe index, gas type, molar mass, methane content percentage, density or viscosity.


Ultrasonic Flowmeters 

The high reliability and low cost of ultrasonic flowmeters have caused them to become a mainstay in natural and processed gas production. While there is no set release date for the new model, the Proline Flow G is poised to become another strong offering from Endress+Hauser in this space.
