Best Practice: National Institute of Metrology - 1

Best practice Minebea Intec stepped in when China changed its policy on charging for heating consumption When the Chinese government decided to charge its citizens for heating on a consumption basis, the National Institute of Metrology in Beijing was required to find a solution. Key facts The National Institute of Metrology in Beijing was faced with the task of laying the foundations for documenting the hot water consumption of individual users. The new calibration system was to employ flow and temperature to determine usage. A precise weighing solution for different capacities was successfully implemented. Minebea Intec developed a weighing solution with high-resolution scales for the measurement of water mass, with capacities of 60 kg, 600 kg and 6,000 kg. Products digital weighing platform IS with IP67 rating Weight indicators Combics 3 with IP69K rating Customer The National Institute of Metrology in Beijing is China’s technical centre of legal metrology. It was founded in 1955 as a non-profit institution with the purpose of providing accurate, reliable and traceable measurements to support China’s economic growth and social sustainability. Customer benefits High level of accuracy High IP rating for rough operating environments +/-2 d repeatability Quick and easy built-in calibration and adjustment feature/functio

Project goal and implementation In 2010, the Chinese government adopted new criteria to calculate utility bills, moving away from using the surface area of dwellings to instead charge on a hot water consumption basis. Resolution higher than 120,000 d High IP ratings for adverse environment conditions Digital displays with inherent communication interference The solution Minebea Intec proposed was the range of For that purpose, 20 million RMB (about €2.5 million) was high-resolution scales with IS weighing platforms, which is invested for the construction of a 1,800 m² laboratory.
