Gas Ultrasonic Flowmeter Introduction
This article introduces the gas ultrasonic flowmeter for natural gas pipeline transportation. Based on the time‑difference principle, it measures upstream and downstream ultrasonic travel times to calculate average flow velocity and volumetric flow rate. Featuring German advanced technology, multi‑channel dual/six‑channel measurement, eddy‑current asymmetric flow detection, laminated electromagnetic shielding and zero‑drift auto‑correction, the meter delivers 1.0‑grade accuracy, ultra‑wide rangeability covering Roots and turbine meters, dual lithium‑battery backup, temperature‑pressure compensation, one‑year mass data storage and intelligent fault alarm, complying with GB/T 32201‑2015.
