Note 1 to entry: No assembly work is to be done on location other than the installation of the complete interface.
Conversion is related to either change of flow pattern, change of flow direction or extension of seat depth.
4 Criteria for the selection of water meters
4.1 General considerations
The type, metrological characteristics, and sizes of water meters should be determined according to the
operating conditions of the installation and the environmental class(es) demanded, taking into account,
particularly, the following:
— the available supply pressure;
— the physical and chemical characteristics of the water, including water temperature and water
quality (suspended particles);
— the acceptable pressure loss across the meter;
— the expected flow rates: the flow rates Q and Q of the meter (as defined in ISO 4064-1:2014|OIML R 49-
1 3
1:2013, Clause 3) shall be compatible with the expected flow rate conditions of the installations,
including the water flow direction(s);
— the suitability of the meter type for the intended mechanical, climatic, electrical, and hydraulic
conditions, including ambient relative humidity, vibrations, electrostatic discharges, continuous
magnetic field, and electromagnetic disturbances;
— the available space and pipe work to install the meter and fittings;
— the possibility of deposition of substances from solution within the meter;
— the sustainability of the power supply of the water meter (where applicable).
When using combination meters, changeover flow rates shall be different from normal operating flow
rates.
4.2 Information to be provided by the manufacturer
Sufficient information shall be provided to enable customers to choose and install a meter that conforms
to particular metrological characteristics.
The influence factors that affect the indicating error of the individual design should be stated. For each
influence factor, the relevant rated operating conditions applicable to the meter should be stated.
4.3 Meters operating in parallel or in a group
4.3.1 For meters operating in parallel, means shall be provided so that the unserviceability of one or
more meters within a group shall not cause the remaining meters to operate at a flow rate in excess of the
limit of operation of each individual meter.

ISO 4064-5:2014(E)
4.3.2 To ensure that water meters of different types operate satisfactorily in parallel, the individual
characteristics of meters operating in parallel shall be compatible, e.g. by grouping them according to
pressure loss, flow rate range and maximum working pressure. However, the installation conditions for
each type shall be respected.
4.3.3 For meters operating in parallel and multiple meter operation, the possibilities of interaction
between one meter or meter type and another to the detriment of their life and accuracy, e.g. pressure
surges and vibration, should be considered.
NOTE Examples of the use of meters operating in parallel and multiple meter operation are:
— meters operating in parallel where the installation of one large meter to meet the maximum water demand
or to cover the required flow rate range is impractical;
— meters installed in parallel where ‘stand by’ meters are necessary to ensure continuity of delivery and flow
measurement in the case of filter blockage or water meter breakdown;
— meters grouped in multiple operation for ease of access, service and reading, where it is necessary to split a
water supply into a number of branches, as for instance in a block of flats, or where it is necessary to unite a
number of metered tributary flows into a common main, as in a water treatment plant.
5 Associated fittings
5.1 General
The water meter installation shall include the associated fittings listed in 5.2 and 5.3 as applicable.
5.2 Upstream of the meter
5.2.1 A stopcock or valve, optionally with the direction of the valve operation indicated.
5.2.2 A flow straightening device and/or a length of straight pipe fitted between the valve and the
meter.
5.2.3 A strainer fitted between the stop valve and the meter.
5.2.4 A means of sealing the connection of the water meter to the water supply line in order to detect
any unauthorized removal of the water meter.
5.3 Downstream of the meter
5.3
