ABSTRACT:
A method and apparatus for monitoring the rate of addition of an additive fluid that is to be added to a main fluid stream in a gas pipeline system. A monitoring interval is defined by selecting a base measurement parameter, and the flow rate of the main gas stream and of the additive fluid are measured during the monitoring interval. The average ratio of additive fluid flow to the main gas stream flow during the monitoring interval is calculated by a data logger, that displays and records the result and the date and time of day that the ratio calculation is made. The monitoring intervals can be defined by a predetermined quantity of odorant flow, a predetermined quantity of main gas flow, or a particular period of time.
