ABSTRACT:
A liquid chemical treatment measuring device as for metering treated chemicals for agricultural seeds. A housing containing a disc-like rotor sandwiched between stationary discs or headers, there being flat faces between the rotary disc and the stationary headers or discs. A rotary disc has a multiplicity of measuring chambers extending endways through its thickness. The stationary discs have supply and recirculation manifold grooves opposite each other and confronting the measuring chambers of the revolving disc, and also an inlet port and an overflow port producing continuous flushing of the measuring chambers and supply and recirculation grooves. The stationary discs or headers also have discharge and relief manifold grooves opposite each other and draining the liquid chemical treatment from the measuring chambers of the revolving rotor and supplying air into the chambers to allow rapid draining. The housing returns spilled and other quantities of liquid chemical treatment to be used for flushing to the reservoir for reuse.
