WL550 OILWATER INTERFACE METERS
HydrocarbonDetection Probe and Flat Tape Measuring Reel
On this page:
GlobalWater’s WL550 Oil/Water Interface Meters measure the depth and thickness offloating (Light Non-Aqueous Phase Liquids or LNAPLs), sinking (Dense Non-AqueousPhase Liquids or DNAPLs) hydrocarbons and water in monitoring wells as small as1/2 inch (12.5 mm) inner diameter using an optical probe for industry leadingaccuracy. Oil Water Interface Meters are available in many different tapelengths. All Oil Water Interface probes are pressure proof and leak proofusing a unique triple-seal design.
Oil/Water Interface Meters Design
Using state-of-the-art electronics, the WL550 Oil Water Interface Meters deliverreliable, rock solid performance in the field. This allows more readingsand more accurate measurements compared to other similar oil water interfacemeters. The oil water interface probes use infra-red refraction to detecthydrocarbons and conductivity to detect water. For heavy viscous oils, theoil water interface meters can detect water quickly by increasing the externalsensitivity control. For highly conductive water (brine), decreasing thesensitivity control prevents bridging so the oil water interface meter does notinterpret a moist probe as being in water. While all water level metershave a water sensitivity adjustment, most other oil water interface probes donot have this feature.
The oil water interface meter’s triple-sealed probes do not need to beaccessed by the user. Using “smart electronics” the oil waterinterface probes will ignore any damage to the optical lens and continue toperform. Similar to a water level meter, the WL550 Oil Water InterfaceMeters produce a solid tone in water and an intermittent light and toneindicates the presence of hydrocarbons. This system doubles the oil waterinterface meter’s battery life and provides better overall performance.
Oil/Water Interface Probes
The standard oil water interface probes are 5/8 inch (16 mm) in diameter;however a unique 7/16 inch (11 mm) probe for ½ inch (12.7 mm) ID wells isavailable. Impact proof oil water interface probes resist all solventsfound in environmental monitoring. The oil water interface meter’s probesare far more chemically resistant than probes using polyurethane or polysulfoneoptics. Stainless steel shrouds protect and secure the oil water interfaceprobes while being more durable than plastic shrouds. The oil waterinterface meter’s optical sensor and electronics work together to ignore minoror severe scratches. Setting a new industry standard the WL550 oil waterinterface probes will detect a 0.02 inch (½ mm) layer of hydrocarbons versusthe typical 0.12 inch (3 mm) hydrocarbon detection limit. The oil waterinterface meters can be recalibrated to 0.04 inch (1 mm), 0.08 inch (2 mm) or0.12 inch (3 mm) hydrocarbon detection limits for user preference. Thewater sensitivity can be increased on the oil water interface meters to ensurequick readings or reduced to avoid bridging when the water contains a lot ofdissolved solids, giving the user ideal performance in all field conditions.
The WL550, Oil Water Interface Meters, have a rugged alumnium bearing.
Oil/Water Interface Meters Reels
Unlike many of the low cost plastic reels on the market which use frames toosmall for enough ground clearance when winding and rarely use a detachablemodule for cleaning the WL550 Oil Water Interface Meters are designedspecifically for environmental monitoring and rugged field use. The oilwater interface meters have lightweight aluminum faceplates with solid metal andmachined nylon components that will not crack under tough field use. Thereare no thin-walled molded components on the oil water interface meters tofracture or break. The oil water interface meter’s easy to use ergonomicframe and hub size are ideal for winding tapes under rough field conditions. A threaded stainless steel axle prevents welds from cracking and resistscorrosion keeping the oil water interface meter’s reel running smoothly. Double sealed ball bearings are added for oil water interface meters with longerlengths. The oil water interface meter’s electronics module is removablefor easy decontamination.
Oil/Water Interface Meters Tapes
Designed specifically for measuring hydrocarbons and organic solvents the oilwater interface meter tapes are four times more accurate than common flat whiteTV cable-type tapes. Oil water interface meter tapes use the highestaccuracy yellow measuring tapes available (0.008% or better guaranteed). All oil water interface meter tapes meet or exceed federal specification USGGG-T-106E(U.S.A) or EEC CLASS ll (Europe). The tape zero point and probezero point coincide exactly to within 0.01 inches (0.254 mm) versus 0.06 inches(1.52 mm) found on most industry standard oil water interface meters. Common flat white tapes use twisted stainless steel wires that can untwist andlengthen up to 1/2 inch (13 mm) per 100 ft (30.5 m) from the oil water interfacemeter cable’s own weight. The unique flat spring steel measuring tape ofthe WL550 Oil Water Interface Meter has a breaking strength of 297 pounds (135kg) allowing it to hang straighter than standard tapes and not stretch (lessthan 0.001 inches (0.025 mm) under a 35 pound (16 kg) load. A clear Kynarjacket covers the oil water interface meter’s conductors protecting thegraduations and numerical markings. The oil water interface meter’s Kynarcovering is about 4-5 times harder (Rockwell hardness) than softer polyethylenewhite tapes making it less likely to be cut or damaged. The WL550 OilWater Interface Meter tapes are chemically resistant to all chemicals found inenvironmental monitoring and will not become softer when exposed to gasoline andother solvents. The covering also makes it easier to decontaminate GlobalWater’s oil water interface meters than meters with embossed tapes.
