Inline Flowmeter for compressed air and gases DN15 (1/2“) – DN80 (3“)

The inline flow meter EE771/EE772, based on the measurement principle of thermal mass flow, is ideally suited for the measurement of flow in pipelines DN15 (1/2”) up to DN80 (3”). Measurement of for instance the usage of compressed air, nitrogen, CO2, oxygen, helium or other non-corrosive, non-flammable gasses.

The flowmeters are setting new standards in terms of measurement accuracy and reproducibility thanks to their applicationspecific adjustment during production. As such, the EE771/EE772 is adjusted under a pressure of 7 bar.

The unique mounting concept with a mounting valve permits rapid installation and removal of the device for periodical calibration. It simultaneously ensures high measurement accuracy through exact and reproducible positioning in the pipe.

Features

  • high accuracy ± 1.5% of reading
  • exceptional reproducibility
  • quick sensor exchange at line pressure
  • broad working range of 1 : 400
  • very service friendly
  • Bus interface for Modbus RTU or M-Bus

Applications

  • Measurement of consumption of compressed air
  • Compressed air counter
  • Mass flow measurement of industrial gases

Insertion Flowmeter for compressed air and gases
DN50 – DN700 (2” – 28”)

The EE776 flow meter is based on the thermal mass flow measurement and is ideal for measuring the flow of compressed air and gases in pipes from DN50 (2”)to DN700 (28”).

With the EE776, the consumption of compressed air, nitrogen, CO2 or other non-corrosive and non-flammable gases can be measured up to a pressure of 16 bar (232 PSI)

Typical Applications

  • Measurement of consumption of compressed air
  • Compressed air counter
  • Mass flow measurement of industrial gases

Features

  • Non-return protection for secure mounting
  • Assembly/disassembly under pressure without flow interruption
  • easy and accurate positioning
  • Pipe diameters DN50 (2”)to DN700 (28”)
  • Pressure range up to 16 bar (232 PSI)
  • Wide measuring range up to 200 Nm/s (39370 SFPM)
  • Bus interface for Modbus RTU or M-Bus
