Product Mode： Fixed mode of products： Test Speed： Number of tests： Equipment size： Description: The capillary flow characteristic testing platform is mainly suitable for testing the flow pressure characteristics of different specifications of inner diameters, lengths, and internal roughness. To accurately control product quality and ensure compatibility with the refrigeration system, high-precision specialized equipment is used to measure its flow characteristics under different operating conditions. Through testing, the refrigerant mass flow rate of the capillary tube is measured at different inlet pressures under precise control conditions, and its flow pressure value is automatically plotted and its flow coefficient is calculated, providing reliable data for the selection, production inspection, and research and development of capillary tubes.
