The Electrode Code

The Electrode Code is a private innovation challenge designed to accelerate advancements in industrial flow measurement technology by solving a critical problem faced by electromagnetic flowmeters (magmeters): electrode coating buildup. Organized by Emerson, a global leader in industrial automation and process control, the initiative invites engineers, scientists, and innovators to develop solutions that maintain the accuracy and dependability of magmeter electrodes under harsh operating conditions. With over 130 years of innovation, Emerson’s portfolio includes leading magmeter technologies under the Rosemount brand, used across sectors such as oil and gas, chemical manufacturing, and water treatment. These meters are trusted for their non-obstructive design and precise measurement capabilities but are increasingly challenged by paraffin, scale, and abrasive particles that impair electrode functionality. The competition seeks to address the significant operational and financial burdens caused by coating buildup. These coatings can distort flow readings, generate noise, and in severe cases, cause complete meter failure. Cleaning requirements are frequent and expensive, leading to unexpected downtime and high maintenance costs. In oil and gas applications, for instance, paraffin buildup may require daily cleaning, while scale in industrial water streams can cause problems over longer periods. The ultimate goal of the challenge is to develop a durable solution that minimizes or eliminates the need for frequent maintenance, extending the operational life of magmeters and preserving measurement accuracy within a ±0.25–0.5% margin of error. Applicants are encouraged to propose coatings, surface treatments, or electrode design innovations that prevent or remove such buildups. Solutions must function in environments that include extreme temperatures ranging from -20°C to 180°C, high-pressure systems, and chemically aggressive fluids. Submissions must demonstrate conductivity for measurement compatibility, exclude PFAS and other environmentally hazardous materials, and comply with regulations such as REACH and RoHS. Desirable features include strong wear resistance (e.g., proven particle abrasion data), broad chemical compatibility, retrofit capability, and cost-efficiency in production and operation. To be eligible, submissions must include a clear technical narrative explaining the proposed concept, supporting materials science, intended performance mechanisms, and integration feasibility with existing magmeter systems. The submission must include quantitative performance data if available, CAD models or technical drawings for clarity, and a validation plan outlining how the solution will be tested under realistic industrial conditions. Key judging criteria include prevention/removal efficacy, robustness, commercial viability, chemical compatibility, retrofit potential, and durability under abrasive conditions. A total prize pool of $30,000 will be awarded, with a $20,000 grand prize and two runner-up awards of $5,000 each. Beyond cash prizes, winning teams may be invited to collaborate with Emerson’s R&D and manufacturing groups, gaining access to validation facilities, expert mentorship, and opportunities for commercialization. The challenge offers a gateway for long-term partnership with one of the world’s leaders in flow measurement technology, providing a platform for impactful innovation. The submission portal opens on November 4, 2025, at 9:00 AM EST and closes on February 5, 2026, at 5:00 PM EST. Judging will occur from February 6 to March 5, 2026, with winners announced on March 6, 2026. Proposals must be submitted online via HeroX, with only one submission permitted per team or individual. Eligibility is open globally, provided participants are not from countries under U.S. sanctions. All submissions become the property of the sponsor upon entry, and selected finalists must grant a non-exclusive license for commercial use while retaining ownership of their intellectual property.
