FCC Cautions
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.

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® 3250 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 20 PSI (1.4 bar).
1.2 Installation requirements
Prior to installation of flowIQ® 3250, the system should be flushed
while a fitting piece replaces the meter.
Please check that stop valves are tight and operate as intended and
that the pipe system is without corrosion and damages. Damaged
components, if any, must be replaced.
Close the main stop valve in front of the meter and let a tap run
until the pressure in the system has been equalized. Close the stop
valve after the meter before disassembling the pipe system.
Having assembled the pipe system, all sealing surfaces of existing
couplings must be cleaned to remove possible remaining pieces of
gasket. Remove adhesive wafers from the meter’s inlet and outlet
and mount the meter. Always use new gaskets in original quality.
The flow direction is indicated by an arrow on the meter. Install the
meter with an orientation that makes it easy for the consumer to
read the display.
During installation it must be secured that the meter is mounted
without mechanical bias in the connection pipes. Do not attempt to
correct oblique piping by means of the meter.
At the same time 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.If meters
are mounted in meter pits or outdoors, both the meter pit and the
meter must be protected against freezing.
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 either side of the meter.
Under normal operating conditions no pipe strainer is required in front
of the meter. Check valves must be mounted in accordance with local
regulations.
1.3 Installation angle of flowIQ® 3250
flowIQ® 3250 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 on 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.
A Recommended water meter position.
B Recommended water meter position.
C Used for ‘pit installation’. Air ‘build-up’ may occur.
D The meter functions optimally, but the display is ’upside down’.
1 General information
Read this guide before installing the water meter.
flowIQ® 3250 is a compact electronic water meter used for water
consumption measurement in the tap water supplies of homes,
commercial and industrial buildings.
flowIQ® 3250 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:
- 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.
1.6 Info codes and display
When flowIQ® 3250 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.
