ABSTRACT:
A hazardous fluid transfer system is automated for controlling transfer of hazardous fluid within a closed environment thus providing protection to an operator handling the transfer. The hazardous fluid is transferred from a source container to a target container using a processor controlled pump responsive to flow and pressure within a liquid line. A pre-programmed processor receives pressure and flow signals from transducers monitoring the liquid line. The processor actuates a valve within a vapor line between the source and target containers in response to pressure within the target container. The valve is opened for allowing vapor to accumulate within an accumulator during a filling of the target container and closed for causing the accumulator to force vapor stored in the accumulator into the source container, thus transferring the liquid from the source container to the target container while maintaining fluid transfer within the closed environment.
