    • A multi-product fuel dispensing system is provided for dispensing a plurality of fuels stored in a plurality of reservoir tanks. A fuel delivery conduit delivers a specific grade of fuel from one or more of the reservoir tanks. The conduit includes at least two flow channels, one for conveying a first grade of fuel and another for conveying a second grade of fuel. A nozzle connected to the conduit includes a blend valve for each flow channel. The nozzle can deliver the first grade of fuel, the second grade of fuel or a third grade of fuel comprising a blend of the first and second grades of fuel. An ultrasonic flow meter is mounted in the nozzle to measure the flow of fuel.
    • 提供了一种多产品燃料分配系统,用于分配存储在多个储罐中的多种燃料。 燃料输送管道从一个或多个储存罐输送特定等级的燃料。 导管包括至少两个流动通道,一个用于输送一级燃料,另一个用于输送二级燃料。 连接到导管的喷嘴包括用于每个流动通道的混合阀。 喷嘴可以提供一级燃料,二级燃料或三级燃料,其包括第一级和第二级燃料的混合物。 超声波流量计安装在喷嘴中以测量燃料的流动。

    • A dispensing system (10) that utilizes radio frequencies identification capabilities in a service station environment to reliably and accurately detect an on-board vapor recovery (ORVR) system in a vehicle (26). The dispensing system (10) includes a vapor recovery system (33) for recovering fuel vapors responsive to a fuel being dispensed. The vapor recovery system (33) has a disabling mechanism (42) for selectively preventing its operation. The dispensing system (10) also includes an antenna (22A, 22B, 24A, 24B) for detecting a radio frequency signal from a transmitter (23 or 25) in a vehicle (26). The radio frequency signal may be a single bit indicating that the vehicle (26) has the ORVR system, or may include additional bits indicating a type of fuel to be dispensed. When the transmitter (23 or 25) is within a predetermined distance from the antenna (22A, 22B, 24A, 24B), a controller (20) receives the radio frequency signal from the antenna (22A, 22B, 24A, 24B) and asserts a disable signal (41). The disabling mechanism, responsive to the asserted disable signal (41), prevents the vapor recovery system (33) from operating and thereby eliminates any unwanted accumulation of air.
    • 一种在服务站环境中利用射频识别能力可靠和准确地检测车辆(26)中的车载蒸气回收(ORVR)系统的分配系统(10)。 分配系统(10)包括蒸汽回收系统(33),用于响应于被分配的燃料来回收燃料蒸汽。 蒸汽回收系统(33)具有用于选择性地防止其操作的禁用机构(42)。 分配系统(10)还包括用于检测来自车辆(26)中的发射器(23或25)的射频信号的天线(22A,22B,24A,24B)。 射频信号可以是指示车辆(26)具有ORVR系统的单个位,或者可以包括指示要分配的燃料类型的附加位。 当发射机(23或25)距离天线(22A,22B,24A,24B)在预定距离内时,控制器(20)从天线(22A,22B,24A,24B)接收射频信号,并断言 禁用信号(41)。 响应于被断言的禁用信号(41)的禁用机构防止蒸汽回收系统(33)操作,从而消除任何不希望的空气积聚。

    • A multi-product fuel dispensing system includes a plurality of reservoir tanks. Each tank has a specific grade of fuel stored therein. Each reservoir tank has a fuel delivery line connected thereto. A fuel delivery conduit has at least two flow channels. One flow channel is connected to receive a first grade of fuel from one of the fuel delivery lines, and another flow channel is connected to receive a second grade of fuel, of a lower grade than the first grade, from another of the fuel delivery lines. A nozzle has a connection to receive fuel from the fuel delivery conduit. A first proportional flow control and blend valve is connected in the system for receiving the first grade of fuel. A second proportional flow control and blend valve is connected in the system for receiving the second grade of fuel. A meter is connected in the system for receiving the second grade of fuel. An ultrasonic flow meter is mounted adjacent the nozzle and fuel delivery conduit connection for measuring the flow of fuel through the nozzle.
    • 多产品燃料分配系统包括多个储存罐。 每个罐具有储存在其中的特定等级的燃料。 每个储存罐具有连接到其上的燃料输送管线。 燃料输送管道具有至少两个流动通道。 连接一个流动通道以从燃料输送管线之一接收一级燃料,并且另一个流动通道被连接以从另一个燃料输送管线接收比第一等级低的第二等级的燃料 。 喷嘴具有从燃料输送管道接收燃料的连接。 在系统中连接第一比例流量控制和混合阀以接收一级燃料。 在系统中连接第二比例流量控制和混合阀以接收第二级燃料。 在系统中连接一个仪表以接收二级燃料。 超声波流量计安装在喷嘴附近和燃料输送管道连接处,用于测量通过喷嘴的燃料流。
