Endress+Hauser gets EPA approval for flowmeters measuring biogas and RNG

In Washington, Endress+Hauser announced 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.
