Innovative Water Metering Solutions in Auckland and NZ
Hydrolink wireless water meter system
Systems - Hydrolink B-Meters
Hydrolink is an integrated M-BUS wireless (or hard wired) system for water metering allowing the remote collection of the data thus eliminating any manual operation. In practice, it is sufficient for the operator (equipped with a receiver) to walk within the transmission range of the meter to allow immediate recognition of the end user and automatic storage of the updated consumption data.
The HYDROLINK system uses the M-BUS wireless transmission protocol allowing communication with any other reading systems (electric power, gas) using the same standard, and to use accessories manufactured by third party companies. An M-BUS ready meter can also be manually read so the system also represents a future proof solution and allowing later development into a complete wireless package.
The software supplied with the USB receiver module allows easy meter configuration and data management. The modules initial configuration;
- Encryption enabling
- Alarms enabling
- Data transmission intervals set every 30 seconds
- Data transferring days setup
- Serial number and end user data association
- Consumption history
- Survey list e.g. transmission locations for a group of meters
- Possibility to either detect a specific module, all of them, or only the ones listed in a survey list
- Data export in CSV or XML format
- Serial number
- Date of reading
- Total water consumption in m3
- Total water consumption over the last 13 months in m3 (optional)
- Total backflow consumption in m3
Alarms and Warnings
- Magnetic-fraud attempt
- Attempted optical fraud or error of the optical receiver
- Reverse flow
- Low battery
- Overload at Qmax for a predefined amount of time
- Possible leakage
Remote data collection has two performance levels depending on the application.
Remote USB Device
Multiple wireless MBUS meters* transmit data up to 400m (in ideal conditions) directly to a mobile device or fixed PC via the USB receiver** and software package.
Wireless transmitting module
The transmitting module is a replaceable attachment for M-BUS ready meters with a typical battery life of 10 years in default configuration. It transmits a signal up to 400m in ideal conditions (See Guardian Apartments case study). Once fitted, any attempt to remove or tamper with the device is recorded in the data transmission and red flagged as are any attempts to reverse the meter while any reverse flow is recorded. Each module is paired with a specific meter and automatically recognised by the receiver module.View Wireless Transmitters

Guardian Apartments 2013 - NZ Water Metering 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 month’s 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
