 如何根据序列号识别产品生产日期? 


解答: 设备生产日期对质保来说非常重要,生产日期可以在流量计序列号上查到。序列号构成如下: 现在的: PPYMDDxxxx 以前的: xxxxxPWWY 代表含义: PP = 生产工厂 Y = 生产年份(代码含义见附件) M = 生产月份(代码含义见附件) DD = 生产日(代码含义见附件) xxxx(x) =顺序号 WW = 生产日历周数

解答:
设备生产日期对质保来说非常重要,生产日期可以在流量计序列号上查到。序列号构成如下:
现在的:             PPYMDDxxxx
以前的:             xxxxxPWWY

代表含义:
PP = 生产工厂
Y = 生产年份(代码含义见附件)
M = 生产月份(代码含义见附件)
DD = 生产日(代码含义见附件)
xxxx(x) =顺序号
WW = 生产日历周数

Flowmeter serial number construction 

The flowmeter serial number is constructed as follows:

PPYMDDxxxx 

where

PP = Production factory

Y = Production year (for encryption, see below)

M = Production month (for encryption, see below)

DD = Production date (for encryption, see below)

xxxx = Sequential number

Encryption:
