PRODUCT DESCRIPTION
The flowmeter of the series EE772, based on the measurement principle of thermal mass flow, is suited for
the measurement of flow of air and gasses in pipelines. Measurement of for instance the consumption of
compressed air, nitrogen, helium, CO2 or other non-corrosive and non-flammable gasses.
The EE772 measures the volume flow at standard conditions according to DIN 1343 (P
t
=273.15 K or 0 °C (32 °F). In addition to the standard volume flow, the measurand mass flow, norm flow and
0
temperature are available.
The EE772 has an integrated consumption counter. The consumption quantity is indicated in the display and
is not lost after a power failure. Two signal outputs are available. Depending on the application, the outputs
can be configured as analogue (current or voltage), switch output or as pulse output for the measurement of
the consumption.
1
Signal conditioning with optional display
The enclosure with the signal conditioning is mounted either on
the measurement probe (model A or B compact) or is remote
with a plugable sensor cable up to 10 meter (33 feet) – (model
C with remote probe).
2
Sensing probe with measurement electronics
The interchangeable sensing probe contains the sensor ele-
ment and the measurement electronics, in which the data of the
factory calibration is stored. The sensing probe is easy and
quickly interchangeable in the field, independent of the elec-
tronics for the signal conditioning. After the exchange, the con-
figuration of the outputs is unchanged.
3
Sensor cable (only by model C with remote sensing probe)
The sensor cable allows for the remote installation, up to 10
meter (33 feet), of the sensing probe from the housing with the
signal conditioning.
4
Mounting valve - MultiController
The mounting valve assembly allows for the easy and reliable
installation within the pipeline. During installation in the pipeline,
observe the required inlet and outlet paths (see page 9). The
nominal size of the mounting valve must match the nominal size
of the pipe. The MultiController is suitable for pressures up to
40 bar (580 PSI) and available for pipe diameters DN40 (1 1/2")
to DN80 (3").

The MultiController with hot tap valve allows for the installment
and removal of the sensing probe under pressure without inter-
rupting the process flow.
5
Screw cap
The screw cap, with female thread, is screwed in place if the
flowmeter is not installed and the pipeline has to be used.
