The EE771 is ideal for flow measurement in pipelines with diameters of DN15 （1/2“） up to DN50 （2“）.EE771 氣體流量計適用于直徑為DN15（1/2“）至DN50（2“）的管道中的流量測量。
The EE771 is ideal for flow measurement in pipelines with diameters of DN15 (1/2") up to DN50 (2"). Besides the temperature (T) the sensor
provides the values for standardized volumetric flow (V'n), standardized flow (vn) and mass flow (m'). The integrated totalizer records the
consumption (Qn). The sensor is suitable for air, nitrogen, CO2, O2, argon or other non-corrosive, non-flammable gases with a pressure of
up to 16 bar (232 psi).
Precision and Reliability
The EE771 sets new standards in terms of measurement accuracy and reproducibility thanks to its application-specific factory adjustment at
7 bar. A dynamic pressure compensation via a 2-wire 4 - 20 mA input is available. The E+E hot film sensing element deploying the latest thin
film technology features excellent long-term stability, fast response time and an outstanding reliability.
Easy Mounting
The unique mounting concept including a measurement valve with shut-off function permits rapid installation and removal of the device with only short flow interruption. It ensures high measurement accuracy through exact and reproducible sensing head positioning in the pipe.
Versatile Output Options
The EE771 features two freely scalable outputs configurable as analogue current or voltage output, switch output or as pulse output for consumption measurement. Optionally, the measured data is available at the Modbus RTU or M-BUS (Meter-Bus) interface.
User Configurable and Adjustable
The free EE-PCS Product Configuration Software and an optional configuration adapter facilitate the configuration and adjustment of the EE771.
EE771 氣體流量計適用于直徑為DN15（1/2“）至DN50（2“）的管道中的流量測量。除溫度（T）外，傳感器提供標準體積流量（V'n）、標準流量（vn）和質量流量（m'）的值。集成累加器記錄消費（Qn）。該傳感器適用于空氣、氮氣、CO2、O2、氬氣或其他壓力為高達16巴（232磅/平方英寸）。
精度和可靠性
EE771在測量精度和再現性方面設定了新的標準，這得益于其在工廠的特定應用調整7巴。可通過2線4-20 mA輸入進行動態壓力補償。部署最新薄膜的E+E熱膜傳感元件薄膜技術具有專業的長期穩定性、快速響應時間和專業的可靠性。
易于安裝
*的安裝理念，包括具有關閉功能的測量閥，允許快速安裝和拆卸裝置，只需短時間的流量中斷。通過在管道中精確且可重復的傳感頭定位，確保高測量精度。
多功能輸出選項
EE771具有兩個可自由伸縮的輸出，可配置為模擬電流或電壓輸出、開關輸出或脈沖輸出，用于功耗測量。或者，可在Modbus RTU或M-BUS（儀表總線）接口處獲取測量數據。
EE771 氣體流量計用戶可配置和調整
免費的EE-PCS產品配置軟件和可選配置適配器有助于配置和調整EE771。
