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）。
