燃油加油机检定装置

加油机是一种为机动车添加燃油的液体体积测量系统，它的计量准确程度直接关系到使用双方的利益。建立加油机容量检定装置，对其进行准确计量就显得尤其重要，不仅可以保证加油机容量值的准确可靠和量值统一，更可以保障加油站、消费者的权益及市场经济的运行。 工作原理： 采用容量比较法，即将加油机在各个流量点下的示值VJ与标准金属量器测得的输出实际容量（经过温度修正以后的VBt）相比较，两值之差与修正后的实际容量VBt之比为加油机的基本误差。即EV=(VJ-VBt)/VBt×100%A fuel dispenser is a liquid volume measurement system used to add fuel to motor vehicles. The accuracy of its metering is directly related to the interests of both parties involved. Establishing a fuel dispenser capacity verification device and conducting accurate metrology on it is particularly critical, as it not only ensures the accuracy, reliability and uniformity of the capacity values of fuel dispensers, but also protects the rights and interests of gas stations and consumers, as well as the stable operation of the market economy. Working Principle: The volume comparison method is employed, that is, the indicated value VJ of the fuel dispenser at each flow point is compared with the actual output capacity measured by a standard metal prover (VBt after temperature correction). The ratio of the difference between the two values to the corrected actual capacity VBt is defined as the fundamental error of the fuel dispenser. Namely: EV=(VJ-VBt)/VBt×100%
