LoCI's patented cloud-connected platform is comprised of four components: the Controller, the Sentry, the WellWatcher®, and Liquid Level Management. When operated together, they provide landfill gas collection system operators with data to improve operations, increase methane capture, and reduce landfill gas emissions.


Controller
Wellhead-mounted measurement and control system that provides real-time data and control of each gas collection point.

Sentry
Aggregate gas composition measurement for header system or for overall gas collection system.

Liquid Level Measurement
Measurement and alerting for improved liquid management and removal from collection wells.
WellWatcher®
At the heart of the LoCI system is the WellWatcher® analytics and control platform. It is a cloud-connected data and control platform that provides landfill gas collection system operators 24/7/365 real-time visibility into the entire wellfield — increasing methane collection system efficiency, improving productivity, and reducing harmful emissions.
Features
- Graphical user interface allows real-time wellfield accessibility 24/7/365 via desktop, laptop, or tablet
- Map view or table view with exportable data for both individual wells and aggregate wellfield data
- Operator-configured automation and alert thresholds on a system-wide and individual collection well basis
- Monthly gas collection system reporting
- All landfill gas collection system data is secured using TLS encryption and certificate-based host authentication
Controller
The LoCI Controller is a core component of LoCI's well-mounted landfill gas collection system, increasing gas collection system efficiency, improving productivity, and reducing environmental, health, and safety risks. The LoCI Controller is recommended for all active collection wells in the landfill gas collection system.
Features
- Measures landfill gas composition, including methane, oxygen, carbon dioxide, and calculated balance gas, along with temperature/ambient temperature and barometric pressure
- Measures flow at each collection well using patented Venturi Flo-Wing
- Measures pressure applied to the collection well and available system vacuum pressure in the vacuum riser
- Data displayed in real-time on the WellWatcher® user interface
- Automated control based on LoCI's algorithms, the landfill collection system operator’s set points, or via "remote manual" valve adjustments
- Automated, precision-controlled ball valve that regulates flow at each well
- Actuated ball valves available in 2", 3", or 4" sizes
Sentry
Used in conjunction with LoCI's Controller, the Sentry monitors gas composition at headers or at the inlet to the plant to provide aggregate or sectional data for wellfield oversight. Where a flow meter is installed in a header, or at the aggregate gas collection point, the data from the flow meter can be integrated into the Sentry system. Installation of the LoCI Sentry is recommended to integrate plant-level aggregate gas quality into the LoCI Control system. In addition, Sentrys should be used at gas collection system header lines to provide wellfield regional monitoring, analysis, and troubleshooting.
Features
- Measures landfill gas composition in header, including methane, oxygen, carbon dioxide, calculated balance gas
- Measures header temperature and pressure
- Can connect to an external customer-supplied flow meter
- Data displayed in real-time on the WellWatcher® user interface
Liquid Level Measurement
Liquid levels inside individual collection wells in a landfill gas collection system can significantly impact overall efficiency. Proper control and measurement of liquid levels ensure that a sufficient length of perforated wellbore is exposed, allowing for more effective gas collection.
LoCI Controls can integrate liquid level measurement to improve landfill gas operations, reduce field response times, and establish more efficient downhole pump maintenance.
Features
- Airtight system that measures liquid levels inside wellbore within ±1 foot accuracy
- Text or email alerts notify on-site personnel when liquid levels exceed thresholds
- Standard well caps can be used with LoCI's liquid level measurement system
