ALWAYS use new gaskets
(Kamstrup recommends
EPDM).
The sealing surface of
the threaded connection
must be clean and level.
The adjacent piping must be parallel
and match the meter in- and outlet.
Torque, composite meters
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.

Mounting of antenna
Step 1: Push the base of the helix antenna through the seal housing.
Step 2: Align the antenna by using the terminals and steering pin
before clicking it into place.
NOTE! The antenna must only be mounted on the meter with the
antenna pointing upwards.
Make sure the terminal is dry and clean before clicking the
antenna into place.

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).
You must always use new gaskets in original quality. Following
gaskets can be used:
Cold water
¾” 2 mm EPDM or PE
1” 3 mm EPDM or PE
The flow direction is indicated by an arrow on the side of the meter
case.
During installation it must be secured that the meter is mounted
without mechanical tension in the connection pipes. The couplings
must be tightened with maximum the following torque:
¾” 15 Nm
1” 30 Nm
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.
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.
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’.
A Recommended water meter position.
B Recommended water meter position.
C Standard installation for pits.
D The meter functions optimally, but the display is ’upside down’.
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.
1.1 Permissible operating conditions/measuring ranges
Fluid temperature:
- 1 part body meter: 33 °F...140 °F
- 2 part body meter: 33 °F...120 °F
Pressure stage: 250 PSI
Mechanical environment: Fixed installation with minimum
vibration.
Electromagnetic
environmental class: Residential and commercial
Protection class: IP68-rated (waterproof-submersible)
Climatic environment: 35 °F...140 °F. Condensing humidity.
(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.
1.2 Installation requirements
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.
1.6 Info codes and display
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.
The table below describes the different info codes in the display.
Info code flashes in the
display
Meaning
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.
Burst The water flow has exceeded a prepro-
grammed limit for a minimum of 30 minutes,
which is a sign of a burst pipe.
Dry The meter is not water-filled.
Tamper Attempt of fraud. The meter is no longer valid
for billing purposes.
Radio OFF The meter is still in transport mode with the
built-in radio transmitter turned off. The trans-
mitter turns on automatically when the frst
1/4 gallon of water has run though the meter.
Flow unit Indicates the configured flow unit.
Battery Indication of the battery state.
Active meter
indication
A small square is flashing to indicate that the
meter is active.
Meter
adjustment
If the meter has been dismounted, tested
and the basic flow measurement has been
adjusted this info code will appear.
