Flow Sensor for Compressed Air and Gases DN15 (1/2") - DN50 (2") 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 standardised volume flow (V'n), standardised 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.
