Electronic data can be transferred between workstations in the same office and sometimes even between offices in different cities. Electronic flow computers are used widely by the gas industry for measurement and control purposes. Measurement data is retrieved periodically and stored in the central computer system for accounting, engineering and administrative functions. Control commands are sent by the gas control department or the field operators to the gas flow computers. Data are collected from the field and shared by different departments so that decisions can be made more efficiently. Because of this, an effective communication system between the electronic flow computers, the central computer system and remote offices need to be developed
