A new line of innovative landfill gas wellheads, well caps, control valves and flow meters has been introduced by QED Environmental Systems, Inc. QED's Precision Products line is designed to allow for precise control and direct measurement of landfill gas flow.

QED is the worldwide innovator and first choice for automatic air-powered pumps in landfill gas systems. Building on that reputation, QED has released:

The Precision Flow Meter – the first portable thermal mass flow meter, which can measure and log landfill gas flows directly in SCFM without any calculating or need for temperature compensation. The meter's calibration can be verified without having to send the meter back to the factory. Its superior accuracy and range allows you to achieve better valve settings on perimeter wells, yet also check your main gas flow meter and easily measure header flows. Product tests suggest that its accuracy and sensitivity down to the 0.2 scfm range can also provide new insight into flow patterns in wells and headers.

The New Precision Flow Meter Wellhead (2" and 3") – designed to insure the proper placement of the Precision Flow Meter's insertion probe into the gas stream. Locking pin system allows proper orientation of the probe every time. The wellhead includes the Precision Fine Tune Control Valve.

The Precision Fine Tune Control Valve (2" and 3") – a revolutionary breakthrough in landfill gas flow control. It allows for responsive, linear control of 0-200 scfm for the 2" valve adjustable over 10 complete turns, allowing easy flow adjustment below 10 scfm. The valve has a built-in position indicator for better control of valve settings, and stainless steel handle and shaft for long-term durability.

New Landfill Gas Well Caps – available for both 6" and 8" diameter gas wells. Both allow liquid level measurement without removing the wellhead. The 6" cap is designed for 2" wellheads; the 8" can accommodate 2" or 3" wellheads, and can also be used in combination with a down well pump to remove landfill liquids.

QED's landfill experience extends back over 20 years, from small to very large sites and both municipal and privately held. With an understanding of the challenges and hazards of landfill environments and a continuous program of customer-driven engineering advances, QED has now created these innovative new products for the management and control of landfill gas.
