1.1. Safety Instructions
1.1.1. Intended Use
The flow meter is intended to be used for the measurement of air and other non-corrosive gases in pipelines
only. Consult the factory first before the measurement of wet or filthy gases.
The design of the flow meter allows for the EE771 to be installed in a pressurized system up to PN16 – is
16 bar (230 psi).
Prior to the start of the installation, the system has to be depressurized. Before the installation or
removal of the sensing probe or the screw cap, the measurement ball valve should be closed.
Mounting, electrical installation, putting in operation and maintenance should only be done by qualified
personnel.
The use of the flow meter EE771 in any other way than described in this manual bears a safety risk for peo-
ple and the entire measurement installation and is therefore not allowed.
The manufacturer cannot be hold 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 meter 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.
