Sydney Water, on the of the largest water companies in Australia, will install wireless ultrasonic meters in all new multi-level buildings within the utility’s region.

The utility’s ‘multi-level individual metering (MLIM) policy, which will be compulsory from September 2014, provides for individual metering of units by Sydney Water, and is aimed at improving equity in billing for water usage in multi-level strata developments. With individual metering each unit owner will pay for the water they actually use rather than a fixed portion of the total water used in the building.

According to the policy the developer will be responsible for the cost of setting up the metering arrangement. This will include the cost of supplying individual meters, meter systems, installation and testing.   The metering systems will be capable of being read from outside the building. The metering systems will be wireless systems that can be installed towards the end of construction of the building. The developer and Accredited Meter Supplier (AMS) will make arrangements on when the meters are to be installed.

Sydney Water will take over the meters and metering system after the system has been successfully tested and after the strata plan has been registered.

Enware Australia is the first approved and accredited meter supplier (as report on 1 July on this site) and uses the Hydrometer Automatic Meter Reading (AMR) system which “takes water and energy management of residential, commercial and industrial developments to a new level by providing comprehensive and accurate usage data including leakage information,” according to a statement.

Fully compatible with water, gas and electricity meters, the AMR metering system features flexible data management solutions, including IZAR NET software that has been developed to interface and adapt to most customer billing systems and also provide a powerful database management tool.  Meeting all requirements for data integrity and system reliability strictly stipulated by Sydney Water , there is no mechanical or reed switches technology in connecting the meter to the transmitter module;  but there is ability to count in reverse in the event of reverse flow; and a minimum 10 year battery life.
