求翻译 有关流量计的
Features
Flexible
The same flow meter can be installed on line sizes from 2 to 100" (50 to 2540 mm)
Plug-and-play input/output module options enable custom electronics configuration and/or field retrofits/upgrades; choose two from: pulse, analog, relay, RS-232, RS-485, BTU, and data logger.
Standard, built-in infrared capability for use with optional Windows® software
The compact, NEMA 4X-rated, wall-mounted transmitter has a large, easy-to-read backlit display, which alternates between flow rate and totalized flow with corresponding, user-selectable engineering units. The four-button keypad allows for quick flow meter set-up, featuring EMCO's patented menu-driven EZ-Logic™ user interface. Additionally, the standard infrared communication port can be used with the optional Windows® compatible software package and serial interface device to access all configuration and data recording features.
With buffet-style input/output (I/O) module options, the electronics configuration is easily customized. Two I/O sockets will accept any of seven offered modules: pulse, analog, relay, RS-232, RS-485, BTU, and data logger. The modules are "plug-and-play," enabling field upgrades and/or retrofits. The RS-485 module allows single-point viewing of multiple meters in a master/slave configuration. The BTU module accepts two RTD inputs and performs energy calculations. The data logger collects up to 100,000 data points in non-volatile memory and can be removed from the transmitter under power and connected to a standard PC serial port for downloading and data analysis. Full diagnostics are accessible through the display, the standard
infrared port, and the optional serial communication modules.
参考答案:绝对不是机译，累死我了！
特点
灵活多变
同一种流量计能够线性（平行）安装在2英寸到100英寸（50到2540毫米）的管道上。
即插即用，输入/输入提供常用的电子配置模式并且易于翻新和升级，可选择如下2种形式：脉冲信号，模拟信号，继电器，RS-232/RS-485串口，BTU和数据记录器。
标准内置红外功能，能用于Windows软件。
布置紧凑的墙挂式NEMA 4X-rated数字通讯控制器拥有一个易读的背光式显示屏，能够在即时当前流量和总流量之间自动切换显示，支持客户可选式工程单元（这句你自己斟酌下）。4按键键盘允许对流量计进行快速设定，以及获得EMCO数控专利的菜单式EZ-Logic™用户界面。此外标准红外线通讯接口能够通过与任意与Window系统兼容的其他软件包或者串联界面装置连接，来进入系统配置和数据记录等特色。
具有像自助餐一样方面的输入/输入模式选择，电子配置可容易的由客户自行更改。2套输入/输出接口能够接受以下提供7种任何模块：脉冲信号，模拟信号，继电器信号，RS-232/RS-485串口，BTU和数据记录器。模块都是即插即用的，支持现场升级或翻新。RS-485模块在主/从模式下允许单点观测多个流量计。BTU模块接受RTD输入而且能进行能量计算。数据记录仪能够收集最多100,000个数据点并存贮在只读存储器中，并且在带电情况下能从发射机上移除，并可以与标准电脑的串行接口连接进行数据下载和分析。全面系统诊断能够在显示屏上直接进入，标准红外接口和可选择的串联通讯模块。
