Accu-Flo WellHeads Can Help Prevent LFG
Migration, LFG Emissions & Subsurface Fires
Landfill owners and operators will appreciate the Accu-Flo proven
design that meets the special requirements of landfill gas (LFG)
recovery for environmental compliance and energy production.
Accu-Flo Wellheads provide operators with the gas extraction control necessary to meet more restrictive environmental and safety regulations, thus preventing unnecessary and costly violations.
Accu-Flo helps maximize gas recovery, minimize surface emissions and subsurface migration, helps control hot spots and prevent subsurface fires.
Simplified Data Collection
Accu-Flo simplifies the complexity of measuring wellhead data by incorporating key built-in features including a LFG flow measuring device, gas temperature port, quick-connect gas sample ports and a flow control gate valve.
The patented design expedites the time required to obtain key
wellhead data and determine necessary flow adjustments using
the industry standard instruments, such as the GEM™2000
or other field unit.
Quick and Versatile Installation
The prefabricated Accu-Flo assembly, factory tested and
warranted, is shipped ready for immediate installation – eliminating the cost and uncertainties of field fabricated units. Accu-Flo models are available for installation above or below ground on vertical wells or horizontal branch laterals in flows ranging from 1 to over 300 SCFM. The compact, patented design allows for installation in small 46cm x 61cm x 61cm vaults.
CES-LANDTEC’s Family of Compatible Components
Accu-Flo wellheads are part of the CES-LANDTEC family of
products designed to work in an integrated landfill gas management system. Other proven CES-LANDTEC products include: monitoring instrumentation, landfill gas management software, well-bore seals, condensate knock outs, and automated pumping stations.
The versatile GEM™2000 is designed to interact most efficiently with Accu-Flo wellheads. These units analyze and record the methane, carbon dioxide and oxygen composition of the gas stream, measure static and differential pressures, as well as gas temperature. The GEM™2000 calculates Btu content and gas flow rates. One keystroke stores all the measured information from each well which can then be downloaded to a personal computer.

Flow Accuracy and Reliability
The Accu-Flo system is designed to operate in the wet, abrasive environment typical of landfill gas and still provide exacting control and accurate flow measurements with high dependability and consistency.
A patented feature of the Accu-Flo design is the pre-calibrated gas measurement tube assembly (Accu-Flo body) which extends into a standard vertical or horizontal well casing or branch lateral, creating a
compact installation. The measurement tube assembly houses a modified stainless steel impact tube specifically designed by CES-LANDTEC for harsh landfill gas applications.
Differential pressure readings between the impact tube and measurement tube are used to calculate flow.
To help protect the impact tube from condensate and particulate clogging, common with conventional designs such as pitot tubes and orifice plates, CES-LANDTEC uses an enlarged total pressure port opening and a
separate protected static pressure port. Also, pre-calibration of the measurement tube with a pre-positioned impact tube eliminates the need to take time-consuming traverse measurements normally required for accuracy. |
