該dpf400系列是一個完整的流量指標，以經(jīng)濟的價格提供卓越的性能。單獨的模型可用于流量和累計（帶或不帶平方根提取）批量控制。
該dpf400是前面板可編程為任何規(guī)模的輸入范圍中所需的工程單位顯示。率和總允許在不同的單位速率指示和累計規(guī)模的獨立因素，如流量率和總桶。如果安裝了可選的RS-232或RS-485通信，單位也可以通過遠程計算機編程。
該dpf400是提供4種輸入類型，包括TTL /集電極開路脈沖，低水平的頻率，模擬電壓或電流模擬。單位可以由用戶配置為三個功能：
一個轉(zhuǎn)速表/測量/計量器
一個轉(zhuǎn)速表/積算儀/配料與平方根提取（差壓流量測量）
一批控制器只與多重批計數(shù)，自動/手動間歇循環(huán)，和遠程或本地的停止/繼續(xù)控制（起動控制可與用戶提供的與控制繼電器系列開關(guān)獲得）
選擇的dpf400包括模擬和BCD碼輸出，報警/控制輸出，和RS-232或RS-485通信。
RS-232或RS-485通信選項是雙向的，允許用戶配置dpf400以及讀取電流值。
雖然每個dpf400標配5集電極開路輸出，可選的dp40-r板提供雙7a機械繼電器代替兩個集電極開路報警，為2 7a繼電器和三的集電極開路報警。
