Siemens Flow sensor QVE2x00.0xx CM1N1597en
Building Technologies 2015-02-18
Install the flow sensor where the pipes are completely filled with the medi-
um to be measured, and where gas bubbles and cavitation in the medium
are avoided.
Mount the flow sensor only in the intended position or proper flow direction
(note the arrow on the connecting pipe). The measured flow values will be
wrong if the sensor is mounted in the wrong position or direction.

· The entire measuring path must be free of foreign bodies.
· Plan for sufficient settlement distance before the sensor inlet or outlet
area to avoid eddying effects e.g. by curvatures, steps, changes to diam-
eter, valves, pumps, etc..
· For this reason, strictly adhere to the recommended minimum distances
as recommended in the mounting instructions.
Installation notes
· Comply with all local regulations on electrical systems.
· Use only qualified personnel for electrical installation.
· Always de-energize the system before connecting the wires of the mains
cable.

Do not exceed maximum operating pressure as well as maximum medium
temperature (see "Technical data").
Service notes
· Do not remove a flow switch or its body from a system under pressure.
· The flow sensor is maintenance-free and cannot be repaired by the user.
