WRMTM-40001 iPERL Water Management System Technical Manual
1.3 Features
The iPERL system contains the following features and functionality.
1.3.1 Security Method
A security system has been devised to ensure that only the proper people are allowed to modify
system settings.
1.3.2 Usage Data Logging
Data logging is defined as volume used and maximum flow rate per unit of time. Unit of time is
programmable with a default of one hour intervals. Usage data can be extracted from the system via a
handheld device.
1.3.3 Error Handling
1.3.3.1 Reading Recovery
The system reading is stored on an hourly basis for recovery purposes.
1.3.3.2 Reboot
If the system reboots for any reason, all of the settings will be saved to their latest settings.
1.3.3.3 Reprogram
The iPERL system logs up to five programming sessions.
1.3.3.4 Dead Battery
If, for any reason, the system loses power, the system is able to be powered through the touch
couple to retrieve the last reading.
1.3.3.5 Memory and/or Self Monitoring Alarms
The iPERL system is equipped with self monitoring alarms that detect and report any memory
failures.
1.3.4 Leak Detection
Leak detection is defined as the absence of the transition from active flow to below the defined starting
flow over a configurable time interval. By default, this setting is enabled and the time interval is set to
24 hours. If the transition to zero flow is not seen during the defined time interval, a leak detection flag
is set. The alarm is then saved for a predetermined amount of time after the alarm condition goes away
and after the alarm condition is read.
1.3.5 Reverse Flow
This feature is to alert the utility of a consistent backwards flow. If the system sees a constant reverse
flow of water for more than 15 minutes, a reverse flow flag is set. The alarm is then saved for a
predetermined amount of time after the alarm condition goes away and after the alarm condition is
read.
