PRODUCT DESCRIPTION
The flowmeter of the series EE776, 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 EE776 measures the volume flow at standard conditions according to DIN 1343 (P0 = 1023.25 mbar; t0
= 273.15 K or 0 °C (32 °F). In addition to the standard volume flow, the measurand mass flow, norm flow and
temperature are available.
The EE776 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.
Non-return protection for secure mounting
The patented non-return protection combines three functions in one device:
•
Non-return protection
The sensor can only be pushed in one direction during installation. The sensor cannot return at all,
even if it is released.
•
Seal
By means of an encapsulated O-ring, no compressed air can escape under pressure during assem-
bly.
•
Precise positioning
The precise positioning with respect to immersion depth and orientation is easy to perform, guaran-
teeing accurate measurement results.
Signal conditioning with optional display
The enclosure with the signal conditioning is remote with a plugable sensor cable up to 10 meter
(33 feet)
.
Sensing probe with measurement electronics
The interchangeable sensing probe contains the sensor element 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 electronics for the signal conditioning. After the exchange, the configura
-
tion of the outputs is unchanged.
Mounting grip
With the mounting grip, the sensing probe is inserted and correctly positioned into the pipe line.
Sensor cable
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.
