Compressed air flow meter, EE-776


EE-776 is a thermal mass flow meter dedicated for monitoring compressed air, nitrogen, CO2 or other non-corrosive and non-flammable gases, in pipes from DN50 to DN700 (2″ to 28″) and at up to 16 bar (232 psi).

Air flow

 The EE776 flow meter is based on thermal mass flow measurement and is ideal for measuring the flow of compressed air and gases in pipes from DN50 to DN700 (2″ – 28″). With the EE776 the consumption of compressed air, nitrogen, CO2 or other non corrosive gases can be measured up to a pressure of 16 bar.
Key Features:
  • Low and High ranges 0.2-100Nm/s or 0.2-200Nm/s
  • PC software and USB port for parameter entry
  • Analog, switch or pulse outputs
  • Response time – typically 1 second
  • Optional pressure compensation input 4-20mA
  • Accuracy +/-2.5% of measurement +/-0.5% of span
 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.

By means of an encapsulated O-ring, the pressurized gas 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.
