A system for injecting chemicals, e.g., odorants, from a chemical supply into a conduit or container includes three primary components, a pump for injecting the odorant, a metering device, and a programmable controller. The controller is preferably powered by a solar panel to facilitate use of the system in remote areas for long periods of time. A removable data carrier, such as a memory module, is connected to the controller to collect odorant system event data. The data carrier is removable from the controller and the data therein may be downloaded into an auxiliary audit computer for generation of summary audit reports. The system precisely monitors how much odorant is used per pump stroke and insures that the odorant injection rate remains constant irrespective of environmental or equipment variations which might otherwise cause inaccuracies in the measurement of odorant usage data and/or the fluctuation of the odorant injection rate.
A system for injecting a chemical from a chemical supply into a fluid containing system at a desired injection rate, comprising:
A control system for delivering odorant from an odorant receptacle into a gas pipeline, comprising:
A method for delivering odorant from an odorant receptacle into a gas pipeline, comprising the steps of:
