The flow meter EE771/EE772, based on the measurement principle of thermal mass flow, is ideally suited for the measurement of flow in pipelines DN15 (½") un to DN80(3").
Measurement of for instance the usage of compressed air, nitrogen, CO2, oxygen, helium or other non-corrosive, non flammable gasses.

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 throungh exact and reproducible positioning in the pipe.
The core design of the flow meter is based on the E+E hot film sensor element, which is produced using the most modern thin film technology.
This flow sensor features excellent long-term stability, a fast response time and an extremely high degree of reliability.
