Abstract
A device and method for continuously controlling the flow rate of an aqueous chemical drawn into a flowing fluid stock includes a metering assembly drawing the aqueous chemical into the inlet of a metering assembly through a flow rate sensor and then through a metering device and into the flowing fluid stock. The flow sensor is monitored and an electronic controller can adjusts the flow rate of the aqueous chemical through the metering device in response to monitoring the flow rate sensor. An electronic controller can also change the direction of the flow of the aqueous chemical into the flowing fluid stock through one ejector to another ejector in response to monitoring at the metering assembly.
