Global Water's WL500 Well Level Sounder sets a new precision standard for well water level measurement. The Water Level Sounder meets or exceeds federal specification US GGG-T-106E (USA) or EEC CLASS II (Europe) for a guaranteed accuracy of 0.008%. The Water Level Sounder uses a full depth-rated stainless steel and teflon probe that is 58-inch (16 mm) in diameter. Sensor electronics are encapsulated in a water and dust proof housing. The Electronics module can be removed so that the entire reel and tape can be cleaned and decontaminated. The flat spring steel core ensures that the level sounder will hang perfectly straight in large and small diameter wells. This provides unparalleled accuracy when compared to the flat white tapes, where kinks in the tape introduce slight errors, in addition to the displacement of water changing the static level.
