A p u r t s m a K 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. 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 to 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. 1.6 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. 1.1 Permissible operating conditions/measuring ranges Fluid temperature:

(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. 1.3 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. The table below describes the different info codes in the display. Info code flashes in the display Flow Meaning The three segments will switch on alternately to indicate flow in the meter Backflow Indication if there is reverse flow Leak Burst Dry Tamper Radio OFF Flow unit Battery Active meter indication Meter adjustment 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 prepro-

grammed limit for a minimum of 30 minutes, which is a sign of a burst pipe. The meter is not water-filled. Attempt of fraud. The meter is no longer valid for billing purposes. 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. Indicates the configured flow unit. Indication of the battery state. 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. You must always use new gaskets in original quality. Following gaskets can be used:

Cold water 2 mm EPDM or PE 3 mm EPDM or PE 1 The flow direction is indicated by an arrow on the side of the meter case. 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). 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:

1 15 Nm 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.

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.

(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 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 meters 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.
