Double chamber container for metering liquid flow
First Claim
1. Liquid flow metering apparatus comprising a liquid container having opposing side walls and a floor, a partition dividing said container into first and second chambers, an inlet port in said first chamber connected to a liquid source, an outlet port in said second chamber connected to a drain conduit, means for sensing the quantity of liquid in said first chamber and for calculating the total liquid volume, said partition comprising a slot including an elongated liquid flow portion extending from said floor in a direction generally parallel to said side walls.

Abstract
The container includes a first chamber connected to the liquid source through an inlet port of a given cross-sectional area and a second chamber connected to a drain through an outlet port of at least equal size. The chambers are separated by a partition having a slot which has an elongated portion extending from the container floor in a direction generally parallel to the container side walls. The area of the elongated slot portion is approximately equal to the area of the inlet port. Liquid level or weight sensors generate signals representative of the quantity of the liquid level in the first chamber to a microprocessor to measure the flow rate. The signals are integrated over time to measure the total volume.
