采集现场压力变送器的电流或电压信号、采集流量仪表的脉冲信号或数字信号、采集水质监测设备的模拟信号或数字信号，提供继电器信号输出，为现场变送器等设备提供5V/12V/24V直流供电电源，控制通信单元和供电单元。

通信单元主要负责现场与调度中心之间的通信。采用GPRS无线通信方式，兼容GSM短信通信方式。工作模式分三种：普通模式、待机模式、休眠模式，不同供电模式选用不同的工作模式。

显示与操作单元主要负责现场监测数据及现场参数的显示，使用按键操作可查询监测数据和设置参数，采用中文液晶显示和防水磁感应按键。

供电单元主要为终端设备提供工作电源，支持三种供电模式：市电供电、太阳能供电、电池组供电。不同的现场环境选用不同的供电模式。

防水设计

城市压力监测点随管网分布，监测终端设备多数安装在观测井内，要求设备防水、防潮。管网监测RTU采用如下防水设计以确保防水效果。
