This dataset contains raw live monitoring data from the final demonstration of the NH3CRAFT project, during which various operational modes were tested. The focus was on monitoring the transfer of ammonia between tanks and evaluating the performance of associated systems, including flowmeters, valves, pumps, and key tank instrumentation such as temperature, pressure, and filling levels. The onshore demonstration involved three metallic tanks (MU1, MU2, and MC3) with capacities of 290, 145, and 155 m³, respectively, a containerized metallic tank (MC4, 20 m³), and a container holding eight composite tanks (CC1 to CC8) with a total capacity of 11 m³. Data were acquired through digital and analog signals from field instruments connected to Programmable Logic Controllers (PLCs), which interfaced with an industrial PC for real-time monitoring. The dataset demonstrates stable system performance during ammonia transfer operations and serves as a valuable resource for assessing system reliability, safety, and efficiency in ammonia storage applications, supporting the broader objectives of the NH3CRAFT project.
