The EE771 / EE772 online flowmeter is based on the principle of thermal mass flow measurement.

It is ideally suited for flow measurement in pipes from DN15 (1/2 ") up to DN80 (3").

It measures for example compressed air, nitrogen, CO2, oxygen, helium or any other non-corrosive and non-flammable gas

Flowmeters set new standards in measurement accuracy and reproducibility through their application-specific adaptation during production. The EE771 / EE772 flowmeter is calibrated at a pressure of 7 bar.

The unique mounting concept with a ball valve allows quick assembly and disassembly of the device for periodic recalibration.

This also allows a great precision in the measurement as well as a precise and reproducible positioning in the piping.

The basic design of E + E's "hot film" flowmeter uses the most advanced thin film technologies.

This flow sensor has excellent long-term stability, fast response time and high reliability.

Two outputs are available for the operation of the measurement data.

Depending on the application, these outputs can be configured as analog outputs (current or voltage), relay outputs or pulse outputs for consumption measurement.
