Water usage metering is usually done manually and very occasionally (perhaps once per year). This provides usage over a long period, but usage patterns cannot be determined.
Water Utilities and high usage water customers often need to know usage patterns, hourly, daily, monthly etc. to better understand how water is being used or wasted in their organizations. These measurements can also be used to detect leaks, so that water usage and the cost of water can be monitored.
Neon Metering Module (NRM) can be wired up to a water meter to act as a logger and communicator. Data readings such as pulses are recorded by the NRM and uploaded to Neon. This data is then analyzed and presented in numerous ways.
Water metering users typically set up the NRM to record metering pulses for 24 hours, and then upload the data once per day at a predetermined time, e.g. midnight. Water metering customers at times may wish to set an alarm point, such that an unusual water usage over a period is signaled as an alarm condition and this is sent to the server at the time the unusual condition occurs.
Water meters usually provide a pulse output based on, say 1 liter per second, 10 liters per second and so on. When considering logging systems, you may wish to have a Neon Remote Terminal or Module record and measure the raw liters per second, or accumulate pulses in some other way by mathematically calculating usage at the logger level before uploading the data to a central server.
As the data is not for any process control requirement, sending the collected water usage information to the Neon Server once per day is usually sufficient.
Scanning – Decide on an appropriate scan interval (this is how often the inputs are read and checked for alarms). Typically: scan inputs each minute and then set equipment to sleep to conserve battery life
Alarms – Decide if there are any high water usage conditions you wish to check for an alarm level, and if that alarm level is exceeded, what action is to be taken. For example: report the alarm information to the server immediately and/or send an email or text to someone
Logging Data to Memory – Decide on an appropriate logging interval (this is how often the data is recorded in memory). Typically: log inputs every 5 minutes and then set equipment to sleep to conserve battery life.
The next consideration is how to power the NRM. A power budget should be performed by Unidata engineers to decide the best power method, either solar panels and sealed lead acid batteries or lithium batteries.
With a daily reporting schedule, and using the single high capacity lithium battery as a power source, NRM units will measure and report for 3 to 5 years before a battery change is needed.
When reporting metering pulses, the NRM can also be set up to report battery voltage, and an alarm can be set to low battery / battery change alert.
To configure a water meter node on the Neon Server, the node type of “Water Meter” is selected from the drop down box available on the Node Details tab. This will change the layout of Neon for nodes of this type in particular a new Multi Chart tab will appear with extra charting options.
A Channel Type option will now be available on the Data Channels tab; this provides extra options when displaying data for channels related to water meters. To activate this feature a channel type of Liters per Second can be selected, this will add extra information to the displayed data and a daily total line in KL will appear on the chart.
A water meter type report can be configured via the Automated Reports tab; Neon can also export Hydstra formatted report files.
Water meters in large organizations often have one main water meter, then several sub meters. The Neon System allows water users to set up a ‘parent and child relationship’ so the ‘child’ water meter usage can be aggregated to check usage by the main ‘parent’ water meter.
