Abstract: This paper will be a discussion of digital telemetry techniques, utilizing both unidirectional and bidirectional systems. The application of gas flow computers to the systems will also be discussed. First of all, a review of analog telemetry techniques is in order before we proceed into digital telemetry. There are three basic types of analog telemetry used today. The first type is utilized over short distances, and usually limited to private circuits not exceeding 5000 feet. The system is utilized at such locations as compressor stations, regulator stations, etc. with telemetering of variables from the point of measurement into a central control panel. The system is called current telemetering where the variable to be telemetered is normally represented as a 4-20 m.a. d-c signal, Since the signal is two-wire transmission, power is required only at the receiving end, thus keeping the system simple and keeping installation at a minimum.
