LoCI System

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

Controller

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

Sentry

Sentry

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

Liquid Level Measurement

Liquid Level Measurement

Measurement and alerting for improved liquid management and removal from collection wells.

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 (methane, oxygen, carbon-dioxide, calculated balance gas), landfill gas temperature and ambient temperature and barometric pressure
  • Measures flow at each collection well using patented Venturi Flo-Wing to reliably measure flow
  • Pressure applied to the collection well, as well as system or available vacuum (pressure above or below the LoCI actuated valve).
  • Actuated ball valves available in 2", 3" or 4" sizes
  • Data displayed in real-time on the WellWatcher® user interface
  • Automated, precision-controlled ball valve that regulates flow at each well
  • Automated control based on LoCI's control algorithms or landfill collection system operators' collection system set points, or via "remote manual" valve adjustments.

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 and also Sentry’s should be used at gas collection system header lines to provide wellfield sectional analysis to help diagnose sub-surface or air intrusion from a section of the collection system.

Features

  • Measures landfill gas composition in header ((methane, oxygen, carbon-dioxide, calculated balance gas))
  • Input of external thermister for header or aggregate landfill gas temperature, or input of external flow meter data.
  • 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 gas collection system efficiency. Proper control and measurement of liquid levels ensures that a sufficient length of perforated wellbore is exposed, ensuring effective gas collection.

LoCI Controls can integrate liquid level measurement into the LoCI Automated Landfill Gas Collection System and WellWatcher® user interface to improve landfill gas operations, reduce field response times, and ensure more efficient downhole pump maintenance.

Features

  • Air-tight measurement system that measures liquid levels inside wellbore within +/- 1 ft. accuracy
  • Electronic alerts (texts or e-mails) to notify on-site personnel when liquid levels exceed thresholds
  • Standard well caps can be used with LoCI's liquid level measurement system

WellWatcher®

At the heart of the LoCI system is the WellWatcher® analytics and control platform. It is cloud-connected data and control technology 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

  • Cloud-based user interface and data analytics platform providing landfill gas collection visibility, improved safety, boosted performance, and streamlined operations
  • 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 basis as well as on an 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; servers are hosted at Amazon Web Services (AWS), an ISO-27001-certified cloud provider
