Questions about our products?

The EE776 is a thermal mass flow meter dedicated for monitoring compressed air, nitrogen, CO2 or other non-corrosive and non-flammable gases. It can be employed in pipes from DN50 to DN700 (2" to 28") and at up to 16 bar (232 psi).

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: 

Non-return protection
The probe can only be moved in one direction during installation, and it cannot return at all, even if it is released.

Seal
By means of an encapsulated O-ring, the pressurized gaz cannot leak during probe mounting.

Probe positioning
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.

FAQ

  • What is the difference between Modbus RTU and Modbus TCP/IP?

    The main difference is the hardware interface. The Modbus RTU protocol runs on RS485 Hardware while Modbus TCP/IP protocol on Ethernet hardware.

  • What calibration certificate is included in the standard scope of supply of the E+E mass flow sensors?

    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".

  • Can E+E supply an accredited calibration certificate with the mass flow transmitter?

    Accredited calibration certificate formass flow is available upon request, please see our calibration website.

  • How can I adjust the mass flow transmitter?

    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

  • E+E mass flow measure the Normal Volume referring normal conditions 0 °C and 1.013 mbar (14,7 psi, 32 °F), according standard DIN 1343. Can I change the normalization parameters according my standard definitions?

    Yes. Use the E+E Product Configuration Software, section "Process Parameters". See operation manual of the specific E+E device.

  • What is the difference between a 2 wire and a 3 wire current output?

    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.
