Abstract: Remote supervisory control with telemetering can be accomplished by the use of either a relatively simple installation containing a minimum of instrumentation, or an all inclusive set-up with many and varied devices. Most of the comments contained in this paper will be cocerned1 with an installation in which a particular choice is made of selecting controllable pressure points within a distribution system so that a minimum of locations and a maximum of operating experience can give an overall integrated view of the utilization of the system. The degree of accuracy with which a supervisor can scan the information and inerpret the overall picture presented by telemetering depends on three basic ingredients making up what is now known as remote supervisory control. These ingredients are the units in the field, the units in the dispatchers office, and the connecting means between field and office units to provide the continuity of service necessary for remote operation. A great variety of equipment of all kinds is available to give superb remote control, and the supervisor often has a difficult task to select the equipment best suited for the job. The field units may consist of flow rate changing devices or regulators, telemetric transmitters for measuring any variable, and controllers. The office units will be recording or indicating types to show when any desired or undesired change has been made in the utilization of the distribution system by the remote control circuitry or by some extraneous source. The connecting means generally is through at least a partly solid wire circuit (leased or owned) or a radio type transmission between field and office units.
