CL-1-8 installation structure and dimensions reference diagram

The following drawings show the recommended length of straight pipe section when installing the typical CL-1 product of CL series ultrasonic gas flowmeter. The installation shall comply with the relevant technical requirements of GB/T 18604.

CL-1 series product measuring bores covering from DN50 ~ DN700, measuring accuracy reaches 0.5 above, it is suitable for accurate and reliable custody transfer of natural gas long distance pipeline, also it is suitable for all kinds of medium and low pressure situations under the condition of natural gas, city gas, large industrial users with high precision flow metering and monitoring.
At present, there are CL-1-4S and CL-1-8 two products in this series.
CL-1-4S is a four-paths product, which is the first domestic product applied to the custody measurement of high-pressure natural gas. The product technology is at the international advanced level, and has been widely used in the PipeChina, and other natural gas pipeline projects.
CL-1-8 is the latest eight-paths product, and its technical performance is in the international leading level, which can provide users with higher accuracy guarantee and reliability redundancy. lt has a larger scale ratio of 80:1 to 100:1 with more sound paths, so that in the condition of one individual sound path failed, it could continue to use other normal sound paths for effective measurement and does not affect the normal use of users; The 8 sound paths in the paralleled reflection pair layout can effectively solve the influence of the flow field distortion in the pipeline, such as turbulence flow, swirling flow, pulsating flow and other uncertain flow fields on the gas ultrasonic measurement accuracy, besides it has lower requirements on the length of front and rear straight pipe sections with convenient installation and application in compact sites.
