INTEGRAL AUTOMATED SYSTEM FOR COMPENSATION OF EFFECT OF NATURAL GAS QUALITY EXPRESSED BY THE MEASURED WATER DEW-POINT TEMPERATURE ON THE RESULTS OF MEASUREMENT OF NATURAL GAS FLOW RATE

摘要

An integral automated system for compensation of effect of natural gas quality expressed by measured value of water dew-point temperature on the results of measurement of natural gas flow rate includes a pipeline (1), primary measuring transducer of pressure drop FE/1-1, normalizing transducer of pressure drop DPY/1-2, normalizing transducer of absolute pressure of gas PY/2-1, primary measuring temperature transducer TO/3-1, normalizing transducer of gas temperature TY/3-2 and programmable device (controller) – calculator of flow rate FQI/1-3. Additionally it includes the circuit for measurement of water dew-point temperature comprising primary measuring transducer of water dew-point temperature WE/4-1 and normalizing transducer of water dew-point temperature WY/4-2 and the circuit of programmed control comprising the programmed master HC/1-4 and automatic control device (controller) FQC/1-5 with drive (1-6) of the control unit PO 1-7 mounted to discharge pipeline (2).
