Process for maintaining liquid supply

摘要

A method for ensuring that sufficient liquid is maintained in a liquid reservoir which is distant from a liquid supply station, comprising periodically determining the amount of liquid in the reservoir and sending the periodic determinations to a signal receiver for determination of the actual usage rate of liquid from the reservoir, sending a signal from the receiver to a remote supply station if certain defined mathematical operations indicate that liquid resupply is needed, and sending liquid from the remote supply station to the liquid reservoir.
