Q.E.D. Environmental Systems Inc. (QED)’s Precision Level Reader (PLR), is an accurate, safe and efficient method for determining leachate and/or condensate levels in gas wells. With QED’s new PLR device, liquid levels are detected within seconds and are recorded with a time, date and location stamp with no need to interrupt the vacuum in the well. Using a permanently installed weight and tube, the PLR engages a micro-compressor and differential sensors to determine a water level reading that is never affected by foam and will not cross-contaminate from well to well. With no need for a water tape or well seal removal, level readings take a fraction of the time and effort, with no exposure of technicians to dangerous gases or liquids in the process.
