Questions about our products?

The EE772 is a thermal mass flow meter for compressed air and gases. Irrespective of pressure and temperature, the EE772 flow meter registers mass flow, volumetric flow or standard flow.

The flow meter can be used effectively to measure the consumption of compressed air, nitrogen, CO2 or other non-corrosive gases.

The gauge mounting block allows for the installation and removal without flow interruption. Regular calibration, without taking into account the device downtime, is therefore always an option. Besides the mass flow probe, the gauge mounting block with hot tap valve can accomodate also a dew point and a pressure sensor.

EE772 flow meter 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 meter 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 EE772 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.
