The EE776 flow meter set new standards in terms of safety and easy assembly. The patented non-return protection combines three functions in one device:
The probe can only be moved in one direction during installation, and it cannot return at all, even if it is released.
By means of an encapsulated O-ring, the pressurized gaz cannot leak during probe mounting.
The precise positioning with respect to immersion depth and orientation is easy to perform, guaranteeing accurate measurement results.
An optional ½" ball valve enables the installation and removal of the probe without interruption of the gas flow. Every EE776 flow meter undergoes a precise factory calibration procedure at a pressure of 9 bar (130 psi), the corresponding calibration certificate is included in the standard scope of supply.
EE776 features two outputs which can be configured as analogue (current or voltage), alarm or pulse output for consumption metering. The EE776 flow meter 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.
