The unique assembly concept with one mounting valve permits simple
installation and removal of the sensors for regular calibration, and also
ensures a high level of measurement accuracy via precise and reproduc-
ible positioning of the ow sensor in the pipeline.
The MultiController with hot tap valve is used in applications where ow
interruption is not permissible. The owmeter can be removed for calibra-
tion or maintenance with no ow interruption.
The MultiController assembly is suitable for applications up to 40 bar
(PN40) and is available for line sizes of DN40 (1 1/2“) to DN80 (3“).
The additional option of integrating dewpoint or pressure sensors saves on
installation costs. The MultiController mounting valve makes it easy to set
up a comprehensive compressed air monitoring system.

EE771 - Assembly with ball valve
The ball valve assembly allows for the exact alignment of the sensing
head within seconds during instalment and removal, with only interrupting
the process flow for a short moment.
The ball valve assembly is suitable for pressures up to 16 bar
(232 PSI) and
available for pipe diameters DN15 (1/2") to DN50 (2").
The ow meter consist of the transmitter and the mounting valve. The transmitter is modular and consist of the
probe and the evaluation electronics. The measurement probe contains the sensor element and the measure-
ment electronics, in which the data of the factory calibration is stored. The enclosure with the signal conditioning
is mounted either on the measurement probe (compact) or is remote with a sensor cable up to 10 meter
(33 feet).
Measurement of consumption (totalizer)
The EE771/EE772 holds an integrated counter for the usage. The amount is indicated in the display and
stored; the data will not be lost due to a power outage. The availability of the consumption amount as a free
congurable pulse output is another helpful feature.
