Water Management Device (WMD)
The primary product in this system is referred to as a Water Management Device (WMD). It contains an electronically controlled valve and microprocessor with embedded firmware that enables it when connected to a pulse output water meter, to perform a number of metering functions in addition to those usually associated with a prepaid metering system.
Key functions and features:
- Monitors and controls water consumption
- Has a short range radio used to communicate with the User Interface Unit (UIU), the Data Collector or the Field Service Terminal
- Logs and stores water consumption data over an extended period
- Stores a log of cumulative month-end consumption data suitable to be used for billing purposes
- Detects and warns of possible consumer side leaks
- Detects tamper
The WMD product is usually housed in a meter box assembly incorporating an incoming stopcock, a water meter, piping, and the WMD.
The WMD’s primary function is to monitor and manage domestic water consumption. The water consumption is monitored directly from the pulse output of a conventional water meter via a fully electronic pick up. This ensures high accuracy, reliability and long life.
The WMD is also able to interface to the standard reed switch and electronic pulse output sensors.
WMD, in addition to the prepayment functionality, can also manage the consumer’s water consumption through the use of a real-time clock and integrated, low power, self-latching diaphragm valve.
The WMD contains a bi-directional radio which can be used to communicate with the WMD and to give it commands. The bi-directional communication ability of the WMD provides the infrastructure to allow for real-time control over the consumer’s water supply.
