Scheme Design and Experimental Verification of Gas Sub-Line Measurement

Abstract:

It is well known that the gas flow rate will not be indicated normally in any metering instrument when the really gas pipe rate is less than Flow Meter’s starting flow. This type of leakage indicator is the main factor that affects the measurement shortage of the settlement of the gas transaction, which could affected the production management and economic benefits of the gas company. In this paper, based on the PLC controller technology, the sub-line measurement scheme with double switching mode is designed and accomplished, which is suitable for industrial gas users through rationally designing of controller characteristics and properly adopting the improved split-range control logic. Through testing in site, the sub-line measurement scheme can obviously decrease the measurement shortage of gas pipe network caused by measuring leakage
