Scope<\/b><\/p>\n
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 \u2018self-contained unit\u2019\u2014a 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 \u2018modular metering system\u2019\u2014a 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:
1 The 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.
2 Purchasing guidelines are given in Appendix A.
This Standard applies to meters that are\u2014
(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\u2014
(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\u00b0C to 30\u00b0C. The maximum admissible temperature is 50\u00b0C, which is the limiting condition for the meter.
(D) Ambient air temperature range of ?5\u00b0C to 55\u00b0C.
(E) Ambient humidity range of 0% to 100% except for remote indicating devices where the range is 0% to 93%.<\/p>\n","protected":false},"excerpt":{"rendered":"
