The E+E EE771 / EE772 Inline Flow Meters are thermal mass flow meters designed for compressed air and gases. They are suited for measurements of flow in pipelines DN15 (1/2") up to DN80 (3"). The EE771 / EE772 Flow Meters measure compressed air, nitrogen, CO2, O2, helium or other non-corrosive and non-flammable gasses.

The thermal measuring principle and the well-proven E+E hot film sensor element lead to best long-term stability and fast response time. Outstanding measuring accuracy, even in the lower measuring range is achieved by an application-specific multi-point factory adjustment, which is performed at 7 bar (102 psi). This allows reliable leak detection and corresponding energy savings.

Applications for the EE771 / EE772 include:

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