Vapor recovery system tester
First Claim
1. A device for testing the performance of the vapor recovery of a liquid dispensing and vapor recovery system of the type which has a spout with vapor recovery apertures, the device comprising;
- spout receiving means for receiving the spout and its vapor recovery apertures with space located between the spout and said spout receiving means;
sealing means connected to said spout receiving means for providing a chamber which encloses said space and which is sealed about the vapor recovery apertures; and
means connected to said spout receiving means for sensing air flow through said chamber about the vapor recovery apertures;
whereby a volume of air recovered can be determined and compared with a volume of liquid dispensed to indicate the performance of the vapor recovery system.

Abstract
An apparatus for testing the efficiency of the vapor recovery of a liquid dispensing and vapor recovery system wherein the system uses a spout with vapor recovery apertures. The apparatus includes a device for receiving the spout and its vapor recovery apertures with a space located therebetween. A sealing device is connected to the spout receiving device for providing a chamber which is sealed about the spout and vapor recovery apertures. A device is connected to the spout receiving device for responding to flow through the chamber about the vapor recovery apertures. With this arrangement the volume of air recovered can be determined and compared with the volume of liquid dispensed to indicate the efficiency of the vapor recovery system.
