The flow sensor can measure the consumption of compressed air, nitrogen, oxygen, CO2, argon or other non-corrosive gases. The measurement ball valve permits easy installation and removal with only a short interruption of the flow.
EE771 flow sensor employs the well proven E+E hot-film sensor element with high immunity to contamination, which leads to outstanding long-term stability and accuracy even under harsh operating conditions.
With wide measuring range from 0.5 to 200 Nm/s (100...39370 SFPM) (1:400) and fast response time, one and the same flow meter model can be employed throughout the entire gas supply system. It records accurately even the smallest flow which represent an essential prerequisite for calculating consumption costs or for finding leaks.
Every E+E flow sensor undergoes a precise factory calibration procedure at a pressure of 7 bar (102 psi), the corresponding calibration certificate is included in the standard scope of supply.
The EE771 flow sensor is available with an additional MODBUS RTU or M-BUS (Meter-Bus) interface.

The main difference is the hardware interface. The Modbus RTU protocol runs on RS485 Hardware while Modbus TCP/IP protocol on Ethernet hardware.
The standard scope of supply of E+E mass flow measurement devices includes an inspection certificate according DIN EN 10204 - 3.1. For details on calibration certificates please see our white paper "Calibration and Traceability in Measuring Technology".
Accredited calibration certificate formass flow is available upon request, please see our calibration website.
For readjusting the mass flow sensor you need first of all a reliable reference. In case this is not available, please return the device to E+E for service. Otherwise see the readjustment procedure in the operation manual of the specific E+E mass flow sensor available at www.epluse.com
Yes. Use the E+E Product Configuration Software, section "Process Parameters". See operation manual of the specific E+E device.
Transmitter with "two-wires" technology receive the power from the process, and the signal is carry on return wire (closed current loop). With technology "three-wires" the power supply is separate from current output: 2 wires are the power supply and third carry the signal.
