Intended Use

The inline flow sensor (device) is dedicated to the measurement of compressed air and non-
corrosive gases in pipelines. Please consult the manufacturer before employing the device in wet
or dirty gases.
The inline flow sensor consists of a sensing unit and a gauge mounting block. The sensing unit
may only be installed in the appropriate E+E gauge mounting block. It is not permissible to use
the sensing unit without a gauge mounting block.
Due to the design the flow sensor is appropriate for operation in pressurized systems up to 16
bar (232 psi) (PN16).
It is not allowed to operate the EE741 in explosion hazard areas. The surrounding area of the
sensing unit must not be an explosion-hazard area. When used with flammable gases, explosive
atmospheres in the pipeline must be avoided at all times.
Installation, electrical connection, maintenance and commissioning may only be performed by
qualified, trained and authorized staff.
Use other than described in the present operation manual may represent a security risk for
people and the entire measuring chain and is therefore not permitted. The manufacturer may not
be made liable for injuries damages caused by inappropriate or non-intended use or installation.
To prevent safety risks and damages, and assure full functionality of the device, the user
shall strictly observe the start-up, inspection and maintenance steps described in this manual.
Furthermore, the device may not be manipulated in any other way than described in these
operating instructions, and may not be exposed to any excessive mechanical stress.
The flow sensor may be operated only under the ambient conditions as defined in the technical
data sheet. Use under other ambient conditions may lead to device malfunctions.
