Pit Lid Mounting Kit installation is complete.
Installing in a New Lid
This section describes installation of the 100W and 100WP ERT module in a pit lid without a drilled hole.
To install the 100W in new lids
1. Select a hole location with enough clearance on the bottom side of the lid to attach the threaded clip collar.
2. Drill a 1-3/4 inch hole in the lid.
3. See To install in lids with holes using the Pit Lid Mounting Kit on page 24 to complete installation in a
new lid.
Optional Leak Sensor Installation
Leak Sensors (LS) analyze water flow sound patterns to detect new, evolving, and pre-existing leaks. LS
analysis data is uploaded to mlogonline™ Network Leak Monitoring for data analysis and accessed through a
secure Internet portal unique to your utility. This section describes installation of the Leak Sensor (LS) in a
100W and 100WP ERT module system.
The ERT module stores 20 days of Leak Sensor data. On the 21st day, the ERT module begins to write over
stored data in a first in, first out manner.
The ERT module automatically detects the presence of connected Leak Sensors. The ERT module will
automatically detect the Leak Sensor within 22.5 minutes and begin reading Leak Sensor data. To
immediately detect the Leak Sensor and begin reading data, perform a Check ERT with a handheld computer
running FDM software.
The LS is used in conjunction with both indoor (basement) and outdoor (mounting on the exterior of the
house) 100W and 100WP ERT module installations. LS devices are mounted on a water service pipe or meter
insetter (meter horn) and connect to the Leak Sensor connector on the ERT module as described in To connect
the Leak Sensor to the 100W and 100WP ERT module on page 28. The mounting bracket shipped with the
Leak Sensor accommodates an (up to) 1-1/2-inch OD pipe. An optional mounting bracket is available for pipe
sizes (up to 2 1/2-inch OD).
