General Safety Instructions
NOTICE
Improper handling of the device may result in its damage.
▪
The EE741 enclosure, the sensing probe and the sensing module shall not be exposed to unnecessary
mechanical stress.
▪
Do not apply the supply voltage to the RS485 data lines.
▪
Use the EE741 only as intended and observe all technical specifications.
1.2.2.
Intended Use
The inline flow sensor (device) is dedicated to the measurement of compressed air and non-corrosive and non-
flammable gases in pipelines. Please consult E+E Elektronik if measurement shall be carried out in wet or filthy
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.
The EE741 inline flow sensor is designed for measurement in a pressurized system up to PN16 (16 bar / 230 psi).
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.
WARNING
Non-compliance with the product documentation may cause safety risk for people and the entire
measurement installationand is therefore not permitted. The manufacturer may not be made liable for injuries
damages caused by inappropriate or non-intended use or installation.
▪
It is not allowed to operate the EE741 in explosion hazard areas. When used with flammable gases,
explosive atmospheres in the pipeline must be avoided at all times.
▪
The use of the flow sensor EE741 in any other way than described in this manual bears a safety risk for
people and the entire measurement installation and is therefore not allowed.
▪
The manufacturer cannot be held responsible for damages as a result of incorrect handling, installation,
and maintenance of the equipment.
▪
To avoid health risks or damage to the equipment, the installation should not be operated on with tools,
which are not specifically mentioned or described in this manual.
▪
Excessive mechanical stress and inappropriate handling must be avoided.
▪
A short interruption of the flow using the measurement ball valve cannot be avoided when exchanging the
sensing probe.
▪
The flow sensor can only be utilized in accordance with the conditions defined in the technical data.
Otherwise, inaccuracies of the measurement will occur and equipment failures cannot be ruled out.
▪
For the safety of the user and for the functionality of the equipment the recommended steps by the
manufacturer to put into operation, to test and to maintain should be taken and completed.
NOTICE
Failing to follow the instructions in this user manual may lead to measurement inaccuracy and device
failures.
▪
The EE741 may only be operated under the conditions described in this user manual and within the
specification included in chapter 10 Technical Data.
▪
Unauthorized product modification leads to loss of all warranty claims. Modification may be accomplished
only with an explicit permission of E+E Elektronik Ges.m.b.H.!
