Product Specifications
Product Description
The CL series ultrasonic gas flow meter p is based on ultrasonic velocity difference methodology, designed and manufactured according to national standard GB/T18604-2014 and verification regulation JJG1030-2007, at the same time referring to American AGA NO.8, NO.9, No.10 report.
With a wide product range, CL series could be used in different application areas in a simple way and requiring less maintenance. It's a precise and stable gas flow metering solution for high pressure gas pipeline, municipal gas grid, commercial or industrial gas end-user, or process control application.
The products are featured with advanced technology, high accuracy, stability and reliability, long life cycle, and less maintenance.
Application Areas
Metering of high pressure long distance gas pipeline
High pressure gas storage
Municipal gas metering management (natural gas or coal gas)
Metering in gas field gathering and transporting
Metering after gasification of CNG and LNG
Metering of coal gas, coal bed gas, and rock layer gas
Metering of blast furnace gas, oven gas, and process control
Industrial gas making and utilization
Metering of gas emission (track gas, torch gas, industrial waste gas, etc.)
Product Features
Meet the requirements in GB/ T 18604,GB/T17747,JJG1030,ISO CD17089,AGA NO.8,NO.9,NO.10 report.
Explosion-proof design
Convenient installation and simple maintenance.
No moving parts, no flow blocking components, no pressure loss.
Depending on the different nominal diameter, the max range ratio is 1:100
Suitable for bidirectional flow metering
Suitable for a wide range of temperature and pressure, meets the requirements in low pressure, such as municipal gas grid.
Output data of nominal volume, standard volume and energy volume.
Corrected volume can be displayed at filed or transmitted to control room.
Based on the methodology of sound velocity difference, precisely compensating the composition influence on sound velocity.
High noise resistance, low parameter drift, high accuracy, high repeatability, high reliability.
Two path or four path meeting different needs of users.
Metering pipe diameter ranging from DN50 to DN5000, flange referring to metric or British system.
In 2002, Shanghai China Nuclear Weisi Instrument Co., Ltd (Weisi) was founded by Shanghai Puyuan Co., Ltd, a subsidiary of China Nuclear Group, along with several other organizations. After years of R&D, Weisi had launched its ultrasonic gas flow meter product with in-house technology. Up to now, Weisi is the only China company providing this product.
With the world class technology, Weisi was the first to introduce field volume display product, and the pioneer in small diameter and low pressure pipeline application. In 2005, Weisi ultrasonic gas flow meter was listed in National Torch Program; In 2008, it was honored as Shanghai Important New Product; In 2009, Weisi was granted as Shanghai Hi-tech Company, and was listed in Important First Locally Developed Equipments Subsidy Grogram by National Development Committee and National Energy Bureau; In 2010, Weisi product was honored as Mass Produced Hi-tech Product by Shanghai government.
With leading technology, wide product range, and great quality, Weisi ultrasonic gas flow meter was the mainstream flow meter in nation natural gas pipeline grid, and was used in municipal gas pipelines, end user custody transfer, as well as special venting system and process control. In CNPC's West to East Gas Pipeline, Sinopec's Sichun to East Gas Pipeline, CNOOC's LNG project, as well as every other domestic or overseas project, Weisi product is metering the gas precisely and stably, requiring nearly no maintenance effort at the same time.
