该dpf400系列是一个完整的流量指标，以经济的价格提供卓越的性能。单独的模型可用于流量和累计（带或不带平方根提取）批量控制。
该dpf400是前面板可编程为任何规模的输入范围中所需的工程单位显示。率和总允许在不同的单位速率指示和累计规模的独立因素，如流量率和总桶。如果安装了可选的RS-232或RS-485通信，单位也可以通过远程计算机编程。
该dpf400是提供4种输入类型，包括TTL /集电极开路脉冲，低水平的频率，模拟电压或电流模拟。单位可以由用户配置为三个功能：
一个转速表/测量/计量器
一个转速表/积算仪/配料与平方根提取（差压流量测量）
一批控制器只与多重批计数，自动/手动间歇循环，和远程或本地的停止/继续控制（起动控制可与用户提供的与控制继电器系列开关获得）
选择的dpf400包括模拟和BCD码输出，报警/控制输出，和RS-232或RS-485通信。
RS-232或RS-485通信选项是双向的，允许用户配置dpf400以及读取电流值。
虽然每个dpf400标配5集电极开路输出，可选的dp40-r板提供双7a机械继电器代替两个集电极开路报警，为2 7a继电器和三的集电极开路报警。
