Caution: Changes or modifications not expressly approved by the
party responsible for compliance could void the user’s authority to
operate the equipment.
RF Exposure compliance statement: This device may be used with
no restrictions, since the source-based time-averaged output power
is ≤ 60/f(GHz) mW.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
1 This device may not cause harmful interfenrence, and
2 This device must accept any interference received, including
interference that may cause undesired operation.
ALWAYS use new gaskets
(Kamstrup recommends
EPDM).
FCC Cautions
Torque
If a pipe installation is skewed to the effect that the prescribed
tightening torques would be exceeded, a meter setter or yoke
should be installed.

1 General information
Read this guide before installing the water meter.
flowIQ® 2250 is a compact electronic water meter used for water
consumption measurement in the tap water supplies of homes,
commercial and industrial buildings.
flowIQ® 2250 is hermetically closed, and it is, therefore, impossible
to service the meter without breaking the seal. This means that all
service, must be carried out by an authorized Kamstrup Service
Centre.
Certain changes of configuration, however, are possible via the
built-in optical eye without dismounting the meter from the
installation. Further details appear in the data sheet.

(indoors mounted in utility rooms and
outdoors in meter pits). Installation
in direct sunlight must be avoided.
The meter must be protected from
freezing as well.
If a tight connection cannot be obtained within these limits, the
pipe installation must be corrected in order to remove strains.
Alternatively a meter setter or yoke must be installed.
Mounting the meter you must make sure that the threaded length
of the couplings does not prevent proper tightening of the sealing
surface and that couplings with similar pressure ratings are used.
For sealing, use the sealing wire holes on the lower side of the
threaded connections.
Service
When the meter has been mounted in the system neither welding
nor freezing is allowed. Dismount the meter from the system before
starting such work.
In order to facilitate replacement of the meter, shut off valves
should be mounted on both sides of the meter.
The meter is supplied with a strainer in the inlet. Check valves must
be mounted according to local regulations.
1.3 Installation angle of flowIQ® 2250
flowIQ® 2250 can be mounted at all angles and positions.
Kamstrup Headquarters recommend that the display is mounted so
that it is easy to read, if possible.
Thus, the meter can be mounted in a plain horizontal installation. It
can be mounted vertically in an ascending pipe, it can be mounted
at any angle and it can be mounted with the display pointing
downwards, e.g under a roof.
Mounting the meter in a downpipe, you must be aware that the
display in that case will be ’upside down’.
Prior to installation of flowIQ® 2250 the system should be cleaned
and flushed thoroughly. Then, install the meter with matching
couplings.
If an existing install, remove all traces of old gaskets and insert new
gaskets in original quality. Kamstrup recommends EPDM gaskets ,
which are included.
Install the meter according to the flow direction indicated by an
arrow on the side of the meter housing. An electrical grounding wire
must be installed according to local electrical regulation and for
safety reasons.
During installation it must be secured that the meter is mounted
without mechanical tension in the connection pipes. The piping
must be in line and match the meter. Do not attempt to install the
meter in a misaligned pipe system or in an opening that is too long.
Jacking the piping into place with the meter will seriously damage
the meter.
In a properly aligned piping system with new gaskets, you should be
able to mount and tighten the couplings by hand.
After hand-tightening the coupling nuts, using an open-end wrench,
tighten an extra ¼ to ½ turn on each coupling. Maximum allowable
torque is 30 Nm.
When flowIQ® 2250 leaves Kamstrup Headquarters, it has been
tested and verified and the counter has been reset.
The number of gallons or cu ft are displayed by nine large digits.
Bars over and under each digit are fully customizable, meaning that
they can be used to indicate numbers after the decimal point or
indicate if the customer is billed in e.g. tens or hundreds of gallons.
A number of info codes can be displayed, of which
(DRY) and
(RADIO OFF) will be activated and flash upon delivery.
Furthermore, the small square in the bottom right-hand corner
flashes to indicate that the meter is active.
Info code
(DRY) indicates air in the meter, the info code
disappears when the meter is water-filled.
The info code
(RADIO OFF) indicates that the meter is still in
transport mode with the built-in radio transmitter turned off. The
transmitter turns on automatically when the first quarter gallon of
water has run through the meter. The radio transmitter remains on,
and the info code signal in the display switches off.
When the water is running, the symbol
(FLOW) will appear in the
display. If the water is stagnant, the symbol will be off.
The table below describes the different info codes in the display.
Info code flashes in the Meaning
display
Flow
The three segments will switch on alternately
to indicate flow in the meter
Backflow
Indication if there is reverse flow
Leak
The water has not been stagnant in the meter
during the past 24 hours. This can be a sign
of a leaky faucet or toilet.
The water flow has exceeded a preprogrammed limit for a minimum of 30 minutes,
which is a sign of a burst pipe.
The meter is not water-filled.

1.2 Installation requirements
1.6 Info codes and display
Recommended water meter position.
Recommended water meter position.
Used for ”well installation”. Air build-up may occur.
The meter functions optimally, but the display is ’upside down’.
1.4 Straight inlet
flowIQ® 2250 requires neither straight inlet nor straight outlet to
meet applicable AWWA standards. A straight inlet section will only
be necessary in case of heavy flow disturbances before the meter.
1.5 Operating pressure
In order to avoid cavitation and secure correct measurement under
all circumstances the operating pressure in the pipe installation
should observe the test conditions of AWWA M6 manual. The static
pressure, immediately after the meter (downstream), must always
be minimum 5 PSI (0.3 bar).
Tamper
Attempt of fraud. The meter is no longer valid
for billing purposes.
Radio OFF
Flow unit
The meter is still in transport mode with the
built-in radio transmitter turned off. The transmitter turns on automatically when the frst
1/4 gallon of water has run though the meter.
Indicates the configured flow unit.
Battery
Indication of the battery state.

indication
Meter
adjustment
A small square is flashing to indicate that the
meter is active.
If the meter has been dismounted, tested
and the basic flow measurement has been
adjusted this info code will appear.
