    Abstract - (Show below) - (Hide below)

    Sets out requirements for water meters for use in non-urban applications. It primarily covers metering for irrigation water; however, it is intended that it be used for non-urban water applications other than applications covered by AS3565.1.

    Scope - (Show below) - (Hide below)

    This Standard sets out requirements for water meters for use in non-urban applications. It primarily covers metering for irrigation water; however, it is intended that it be used for non-urban water applications other than applications covered by AS 3565.1.Two types of meters are covered in this Standard, as follows:(a)A ‘self-contained unit’—a meter that defines its own geometry, is able to be pattern-approved as a complete water meter, calibrated upon assembly and supplied by a single supplier.(b)A ‘modular metering system’—a device or group of instruments (which may be supplied as a pattern-approved metering system,) that does not define the installation geometry and requires configuration after installation.NOTES: 1The requirements for these types of meters to demonstrate compliance with this Standard, and hence with the National Framework are described in Section 4 and illustrated in Figure 4.1.2Purchasing guidelines are given in Appendix A.This Standard applies to meters that are—(i)self-contained or modular and capable of continuously determining, within the accuracy limits, the volume of water that has flowed through them; and(ii)continuously updating the volume on a cumulative basis.NOTE: In this Standard a meter installation is considered to include—(a)the meter, its indicating device and all ancillary equipment; and(b)the upstream and downstream pipe or emplacement that may have a material effect on the meter unit.This Standard applies to meters that operate under the following conditions:(A)Closed conduit under full flow.(B)Pressure ranges minimum 0.03 MPa to a value specified by the manufacturer. As a minimum, insertion or clamp-on meters will need to have the same working pressure range as the pipes they are designed to operate in.(C)Working water temperature range of 0.1°C to 30°C. The maximum admissible temperature is 50°C, which is the limiting condition for the meter.(D)Ambient air temperature range of ?5°C to 55°C.(E)Ambient humidity range of 0% to 100% except for remote indicating devices where the range is 0% to 93%.
