GRAEFF and Dr. Wu Hao, President of GRAEFF, have participated in the drafting of the National Standard of the People's Republic of China GB/T 48181—2026 Technical Specification for Differential Pressure Multi-parameter Measuring Transmitter. This national standard was issued by the State Administration for Market Regulation and the Standardization Administration of China on August 28, 2026, and will be implemented on March 1, 2027. Proposed by the China Machinery Industry Federation, the standard is under the jurisdiction of the National Technical Committee 124 on Industrial Process Measurement, Control and Automation (SAC/TC 124).

The differential pressure multi-parameter measuring transmitter is a key field instrument in the field of industrial process measurement and automation control. On the basis of differential pressure measurement, it can simultaneously acquire related parameters such as temperature and static pressure, and is widely used in flow, level and pressure measurement as well as process control in industries including petrochemical, electric power, metallurgy, chemical fiber, rubber and plastics, pharmaceuticals, food and water treatment.

The newly released GB/T 48181—2026 Technical Specification for Differential Pressure Multi-parameter Measuring Transmitter sets unified provisions for the technical requirements, test methods and inspection rules of such products, providing a normative basis for design and manufacturing, selection and matching, and acceptance evaluation. It helps improve measurement accuracy, operational stability and product reliability, and promotes the standardized, regulated and high-quality development of the differential pressure instrument industry.

As one of the drafting units, GRAEFF drew on its years of technical accumulation and engineering practice in the field of pressure and differential pressure measurement to participate in the research and drafting of the standard, integrating corporate practice into industry norms and reflecting the industry's recognition of GRAEFF's technical strength and professional expertise.
