The Model 103 Tag Line is a convenient option for measuring well depth during well construction and backfill layers during monitoring well completion. It is an ideal tool to measure sand and bentonite layers when installing Model 403 CMT® Multilevel Systems or Model 401 Waterloo Multilevel Systems.

The Tag Line uses a tag weight attached to a durable PVDF-coated stainless steel wireline, or PVDF flat tape, mounted on a sturdy freestanding reel. Cables are accurately laser-marked every 5 cm or 1/10 ft. Tape markings are each millimeter or every 1/100 ft.

The cable has a minimum break strength of 270 lbs (122 kg), and comes in lengths up to 300 m (1000 ft.). The tape has a break strength of greater than 220 lbs (100 kg), and also comes in lengths up to 300 m (1000 ft.).

The 316 stainless steel tag weight comes in two sizes. The standard 19 mm x 30 cm (3/4" x 1 ft.) tag weighs 1.5 lbs (0.68 kg) and the narrow 13 mm x 30 cm (1/2" x 1 ft.) tag weighs 0.65 lbs (0.30 kg).

The weights can be clipped on and off the cable. This allows the reel- mounted, marked cable to be used as a support to accurately lower dataloggers, packers, bailers, pumps, or other sampling devices to specific depths in a well. The marked cable improves sampling efforts, and the wireline provides a safe suspension system that is easy to deploy and retrieve.
