Valve Pit Monitoring System Tracks a Variety of Conditions

Radio unit battery offers three-year life span

The Airvac wireless valve pit monitoring system transmits valve pit data and end-of-line vacuum levels to a central SCADA system, which is typically housed within the vacuum station. The valve pit data is transmitted by wireless radios with a proprietary frequency. The radio communication uses a mesh system to communicate between wireless units.

Battery conserving methods are used without sacrificing the ability to get alarms quickly when needed. The types of batteries used are proper for the low temperatures often encountered and the long-life requirements of the application. The pit radio unit battery life is typically three years. 

The main benefits of the wireless valve pit monitoring system are: 

  • A variety of conditions can be monitored: Examples include a valve that stays open longer than normal (e.g. a hung open valve or a valve that stays open for a period of time and fixes itself), a valve that cycles more frequently than normal (i.e. during infiltration or excessive flow) or high sewage level inside the lower sump chamber, which can cause backups. Each of these alarms can be configured to fit specific requirements and maintenance protocols.
  • The ability to track trends: The ability to monitor and track trends at each valve pit, which provides the system operator with information that can be used to make system adjustments, is a key feature.
  • The ability to pinpoint problems: An alert that pinpoints the exact location of a valve failure is sent to the operator.
  • Reduced operator response time: By notifying the system operator of a problem when it occurs along with the exact location, the system significantly reduces the operator’s response time.
  • A more efficient system: All the above benefits result in a more efficient system and reduced operations and maintenance costs.
