Endress+Hauser flowmeters receive dual approval from the US Environmental Protection Agency 

Endress+Hauser today announces that the US Environmental Protection Agency (EPA) has officially approved its ultrasonic and Coriolis flowmeters for measuring biogas and renewable natural gas (RNG) to produce renewable fuels. These approvals are by the regulations at 40 CFR 80.155(a)(1) or (2).

The EPA’s approvals follow thorough reviews of the company’s alternative measurement protocol (AMP) submissions. Endress+Hauser’s Proline Promass Coriolis flowmeters and Proline Prosonic Flow ultrasonic flowmeters have been recognized for meeting the stringent accuracy and precision requirements specified by the EPA. These approvals allow biogas and RNG producers to use Endress+Hauser flowmeters under 40 CFR 80.155(a)(3), provided they meet all other applicable regulatory requirements. 

“At Endress+Hauser, we are fully committed to providing unwavering support to the industry and our valued customers by delivering consistent and reliable measurements that meet regulatory requirements,” said Cesar Martinez Castillo, Natural Gas/LNG Industry Marketing Manager at Endress+Hauser USA. “Our flowmeters are designed to ensure accurate and precise measurement, helping producers comply with EPA regulations and contribute to producing renewable fuels."

The Proline Promass Coriolis flowmeters are renowned for their high accuracy and reliability. These flowmeters can measure mass flow and temperature simultaneously.

Regardless of the gas composition and without the need to calibrate in gas, Proline Promass Coriolis flowmeters show outstanding measurement performance, providing comprehensive data crucial for the efficient production of renewable fuels. The EPA’s approval of these flowmeters as a measurement protocol highlights their performance and reliability. 

Similarly, the Proline Prosonic Flow ultrasonic flowmeters utilize advanced ultrasonic technology to measure the flow of biogas and RNG, calculate the content of methane of it as an important quality feedback, gives feedback about the medium properties like the calorific values and the Wobbe index, ensuring continuous and reliable data collection.

Each is designed with integrated temperature and pressure (only Prosonic Flow G) measurements to meet the rigorous demands of industry, also for challenging wet and very low-pressure conditions.  

Endress+Hauser’s flowmeters play a critical role in supporting the renewable energy sector. By providing accurate and reliable measurements, its products help producers optimize their processes, reduce waste and ensure compliance with regulatory standards. This, in turn, contributes to the broader goal of reducing greenhouse gas emissions and promoting sustainable energy solutions.
