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 气体流量计适用于直径为DN15（1/2“）至DN50（2“）的管道中的流量测量。除温度（T）外，传感器提供标准体积流量（V'n）、标准流量（vn）和质量流量（m'）的值。集成累加器记录消费（Qn）。该传感器适用于空气、氮气、CO2、O2、氩气或其他压力为高达16巴（232磅/平方英寸）。
精度和可靠性
EE771在测量精度和再现性方面设定了新的标准，这得益于其在工厂的特定应用调整7巴。可通过2线4-20 mA输入进行动态压力补偿。部署最新薄膜的E+E热膜传感元件薄膜技术具有专业的长期稳定性、快速响应时间和专业的可靠性。
易于安装
*的安装理念，包括具有关闭功能的测量阀，允许快速安装和拆卸装置，只需短时间的流量中断。通过在管道中精确且可重复的传感头定位，确保高测量精度。
多功能输出选项
EE771具有两个可自由伸缩的输出，可配置为模拟电流或电压输出、开关输出或脉冲输出，用于功耗测量。或者，可在Modbus RTU或M-BUS（仪表总线）接口处获取测量数据。
EE771 气体流量计用户可配置和调整
免费的EE-PCS产品配置软件和可选配置适配器有助于配置和调整EE771。
