Development Of Wet Gas Flow Measurement System

As a particular form of gas-liquid two phase flow, wet gas exists in the nature andthe industrial process widely. As a kind of wet gas, condensable natural gas is one ofclean gas energy with high combustion efficiency, it plays a more and more importantrole in the industrial field. The two phase flowrate measurement without separationhas an important practical significance. The dissertation mainly touches on twoaspects of research first, implementing a comparison system for wet gas flowmetermeasurement on gas gathering station based on Labview, second, developing thewireless communication functions of the two-phase flow computing instrument1. The development of a comparison system for wet gas flowmetermeasurement on gas gathering station based on Labview. This program workstogether with the TTWGF-GD wet gas flowmeter and provides the computing resultscompared with that got by orifice. The comparison system is developed based on theLabview platform and software engineering, running on a PC, which can realize thedata acquisition and processing,display the pressure and temperature waveforms, savethe computing results and give a warning alarm on some dangerous situation. Thefunctionality and reliability of this program has completely satisfied the applicationrequirements of users in industrial fields.2. A wireless communication system is designed for the Wet Gas two-phaseflow computing instrument. The system includes software both for PC and theembedded system. It is programmed by Labview and NI-VISA. By using this system,users can download the flow parameters form the PC to the flow computer, receivethe results of the flow measurement uploaded by the flow computer and store theresults finally.
