Bulk Water Management Device (Bulk WMD)

The Bulk WMD provides a large bore water management and prepaid metering solution. The Bulk WMD is the solution for the management of bulk water supply for customers using larger bore meters, such as zonal meters in both suburban areas and housing estates, schools, oces, factories and state departments.

When connected to an approved pulse output meter and latching valve, the Utility Systems Bulk WMD is able to perform a number of water management and metering functions, including those associated with prepaid metering and advanced metering infrastructure (AMI).

The Bulk WMD can be configured to:

• Dispense a fixed daily quantity of water at full pressure, providing the ability to limit a customer to a pre-agreed level of supply
• Provide prepaid water, or a combination of prepayment and a fixed daily allocation
• Dispense a free daily or monthly quantity of water
• Provide automated meter readings via radio signal to a Utility Systems fixed or mobile data collector

Benefits to the service provider:

• Advanced data-logging functionality to record consumption, detect leaks and tamper, enable load profiling, and aid in dispute resolution
• Accurate zoned water balancing when used with our standard domestic WMDs, using time-synchronised meter readings
• The AMI option allows:

- Parameter configuration and data collection via radio link

- Efficient disconnection and reconnection of supply when used as a consumer connection

• No proprietary billing system is required. Meter readings are available in a simple .csv format. This means that data collected by the fixed or mobile data collector can be seamlessly integrated into most existing utility and municipal billing systems
• In-field programming, testing and interrogation using the meter supplier's field service terminal
• Allows for the management of problematic customers
• Battery life: up to 10 years dependant on use
• IP68 compliant
• Data-logging intervals can be recorded down to a one second interval
• Above/below- ground installation

Features:

• Two configurable daily opening times and open duration
• Volume and/or time-based water management
• Supplied to order and can be configured in the field or stores
• Configurable consumption logging
• Can be set to indefinite daily/monthly carry-over
• Incorporates tamper-proof measures
• Individual customer leak detection
• Pre-paid metering option
• Infrared communication interface
• Advanced data-logging features
• Data collection via radio frequency ISM band

User Interface Unit (UIU):

The UIU is a remote display unit mounted inside the home which interacts with the WMD, Bulk WMD and Aquadata, which are generally installed in a meter box outside a consumer's home. This unit has a lifespan of up to 10-years and is very user friendly. It is a lightweight, wall-mounted device with an easy-to-read digital display, a touch keypad and has the following functionality:

• Remotely display the meter reading as reflected by the WMD
• Display remaining allocation available to the consumer
• Allow for top-up / credit entry for pre-payment applications
• Provide various alarms for the consumer, such as leak indication and low credit
• Display the WMD serial number required for top-up
• Indicate battery life
• Indicate valve status
• Access to emergency water via the WMD
