Guardian Apartments 2013 Case Study
The Guardian Trust Building was one of Auckland’s first high rise buildings, originally constructed between 1914 & 1918 from Kairuru marble and represents a very early example of Chicago-styled striped classical building. This Category 1 Historic Places Trust building was renovated in 2003 and converted into a 180 apartment unit complex.
The conversion included a centralised hot water system
that was proportionally billed to each apartment. Not
surprisingly, some occupants were dissatisfied that the
billing was not linked to consumption and requested
independent water metering be retrofitted.
Being largely steel and concrete construction with
limited access it was decided BMeters ‘Hydrolink’
wireless water meter system was worthy of a trial
installation. The trial would test how effective the
wireless data collection would be within the long,
narrow and winding corridors of the buildings eight
floors and the readings would ultimately show the
occupants had cause for concern.
Rohan MacMillan, from MacMillan Plumbing and
Gas, randomly selected two apartments per floor and
installed hot and cold MBUS ready meters with wireless
transmitting modules. During the next two months,
two readings were taken using the USB wireless
receiver and a laptop computer. Data from 11 of the
32 meters was transmitted and received in the lobby
of the building, while the remaining 21 meters could
be received from the 4th floor lobby and corridor.
The readings taken from the random apartment selection immediately highlighted massive disparities in consumption
ranging from 1m3 to 16m3 during the first months usage confirmed with a similar result from the following months
reading. It didn’t take long for the building management to conclude the trial was an unbridled success and the
remaining 164 apartments were given approval for the immediate installation of the BMeters Hydrolink system.

Wireless Water Meter System
The HYDROLINK wireless water meter system allows the remote collection and transmission of data recorded by the meter via a wireless network. According to budget a range of transmitting and receiving hardware options are available from simple ‘walk by’ to fully automated GPRS transmission solutions.
• Significant time and cost saving
• Attempted fraud detection • Error free data reading and transcription • Easy to use software
The HYDROLINK system uses the M-BUS wireless transmission protocol and will piggy back 3rd party power and or gas reading equipment on the same system.
