The MISSION Model 80 is complete overflow condition transmitter.  It is designed to be installed in Combined Sewer Overflow (CSO) and Sanitary Sewer Overflow (SSO) locations.  It uses digital cellular data channels to tracking conditions and send alarms to personnel regarding the time and duration of manhole surcharges and overflows.  The complete package includes M80 sealed transmitter with 5-year sealed battery, one float (second float optional), and proprietary in-road antenna.

A typical M80 installation is shown below.  The M80 is simply hung from a convenient area near the manhole (no confined-space entry is required).  The floats hang down to levels in the manhole, one at a "surcharge" level and one at a pre-flood levels.  Flows exceeding system capacity tip the float and the M80 transmits an alarm message using the in-road antenna.  Notifications are then sent out to the selected call-out list.
