the product of CL-1-4S type is currently using four path configurations which has taken various kinds of requirements for operating conditions into account. It has effectively solved the influence on the metering precision caused by flow distortions( such as turbulent flow, swirl flow, pulsing flow etc).

     CL-1-4S product has a diameter range of DN80~DN400 with 0.5 class above accuracy which is suitable for precise and reliable fiscal measurement of natural gas with high pressure, large capacity and high quality in the natural gas transportation grid. Moreover, the product is also able to  take high precision metering and monitoring for natural gas, municipal gases which were under various kinds of situations for medium-pressure and low pressure as well as large industrial users.

     Compared with CL-1-4Z, 4S is applied with a built-in transducer which looks more concise in appearance.
