The EE771 flow sensor operates on the thermal mass flow measurement principle and is suitable for measuring the flow of compressed air and gases in pipelines. Gases can be e.g. air, nitrogen, argon, CO2 or other non corrosive and non-flammable gases.
The EE771 measures flow velocity and volume flow at standard conditions according to DIN 1343 (pn = 1013.25 mbar (14.7 psi); Tn = 0 °C (32 °F)). Additionally, it measures mass flow, consumption and temperature. The value of the integrated consumption meter is not lost after a power failure.
Two signal outputs are available. Depending on the ordered version, the outputs can be configured as analogue (current or voltage) output, as switch output or as pulse output for consumption metering and optionally with additional digital interface (Modbus RTU or M-Bus).
The freely available configuration software can be used to configure all outputs, to perform sensor adjustment, to change process parameters and standard conditions, to enter the current process pressure for compensation and to set the communication parameters of the digital interface.
The measured data is indicated on the optional display, with selectable measurands to be displayed. Please refer to chapter 6.3 Display/Indicator with Keypad (Optional).
