regime, switching automatically to normal
routines during a storm. It monitors overflow
discharge, logging the date, time, duration and
volume for regulatory reporting. A vast
selection of alarm functions, control algorithms
and conditional subroutines are included.

The dual-point

and monitor open

allows you to monitor both wet well and

Reservoir Overflow
Monitoring
EnviroRanger monitors rain events and
rainwater levels, as well as overflow events
and flow totals.

Flood Management

Use EnviroRanger to provide remote

monitoring of level in rivers, waterways and
throughout a catchment area. It logs rainfall
information for historical trending, and reports
high levels automatically.
Used with two transducers, it will monitor the
