Australian utility Sydney Water has selected Enware Australia to supply wireless ultrasonic meters for all new multi-level buildings in its service area with the aim of collecting usage data including leakage information, reports Infolink. 

Enware, which is the first approved and accredited supplier for Sydney Water’s new multi-level individual metering policy, will supply a hydrometer automatic meter reading (AMR) system.

The wireless ultrasonic unit allows meter readings to be collected using walk-by or drive-by technology, IZAR M-Bus or fixed network systems and BMS systems for applications ranging from single point to entire plants, complexes or districts.

Data management

Compatible with water, gas and electricity meters, the AMR metering system features data management solutions, including IZAR NET software that has been developed to interface and adapt to most customer billing systems and also provide a database management tool.

Enware’s wireless meters meet the requirements for data integrity and system reliability stipulated by Sydney Water including the use of wireless technology; no mechanical or reed switches technology in connecting the meter to the transmitter module; ability to count in reverse in the event of reverse flow; and minimum 10 years of battery life.

Anti-tampering feature

Instead of mechanical pulses, Enware uses ultrasonic electronic technology, which aids with alerting utilities to meter tampering. It also eliminates the reliability issues typically associated with traditional hard-wired systems caused by damaged, disconnected or poorly connected cables.

The AMR system also provides leak detection and reverse flow counting, helping to deal with water theft and meter tampering, while also reducing maintenance costs by providing a 16-year meter life.
