The natural gas metering system is a system used to achieve the measurement of natural gas transfer, applied to long-distance natural gas pipelines, trade transfer at urban gate stations, and other occasions that require high-precision measurement, to achieve high-precision and high stability measurement of natural gas volume flow rate and energy flow rate.
ANCN Smart ACFC Natural Gas Metering System is designed according to GB/T18603 "Technical Requirements for Natural Gas Metering Systems". It relies on its own advanced and mature gas ultrasonic flowmeter products, equipped with high-precision pressure transmitters, temperature transmitters, flow computers, and flow computer control cabinets. Through personalized customization, it provides users with high-precision, high stability, reasonable layout, and compact metering system products and technical services.
