Tag Line

103 Tag Line Used to Measure Louisiana Sinkhole

A sinkhole in Assumption Parish, Louisiana has been growing for over a year and as of August 18, 2013 is nearly 24 acres in size.

The first video shows the Solinst Model 103 Tag Line being used to measure the depth of the sinkhole, while the second video shows a large number of trees being swallowed in a matter of seconds.

PVDF flat tape or PVDF coated stainless steel wireline


Model 103 Tag Line

The Solinst Tag Line uses a weight attached to a laser marked cable or tape, and is principally designed for use during the installation of monitoring wells. The Tag Line also provides a simple method to measure the depth to the bottom of a well. The cable or tape is mounted on a sturdy free-standing reel with a carrying handle, weight holder and brake.

The Tag Line is perfect for use when installing Solinst Mode 403 CMT Multilevel Systems, as you can easily measure the depth to the top of a backfill sand or bentonite layer during the completion of a well. It is also ideal as a multipurpose marked support line.


New PVDF Laser Marked Cable

The Tag Line uses durable PVDF coated 1/16" (1.6 mm) stranded stainless steel wireline with a minimum break strength of 270 lbs (122 kg). It comes in standard lengths of 100 ft. to 1000 ft. (30 m to 300 m). Other lengths are available by request.

Markings are clearly and accurately laser etched every 1/10 foot or every 5 centimeters of the cable. The laser markings allow the cable to run smoothly over the Tape Guide

Applications Where Tag Lines Are Useful


PVDF Laser Marked Flat Tape

The Model 103 Tag Line is also available with 3/8" (10 mm) PVDF flat tape. The tape has a break strength of greater than 220 lbs (100 kg). It has a thick dog bone design that prevents adherence to wet surfaces, and allows it to hang straight.

The tape comes with laser markings every 1/100 ft. or each millimeter. Lengths are 100 ft to 1000 ft. (30 m to 300 m). Other lengths are available by request

LM2: Feet and tenths: with markings every 1/100 ft.
LM3: Meters and centimeters: with markings every mm

Power Winder

The Solinst Model 101 Power Winder allows ease of use when deploying longer lengths of tape or cable. It is lightweight and simple to attach to the frame of your Tag Line (see Model 101 Power Winder Data Sheet). A standard drill provides power, which turns the rollers that are in contact with the reel. The drill is used at various speeds, in forward and reverse, to turn the reel and unwind and rewind the tape or cable.

316 Stainless Steel Tag

The standard stainless steel tag weight is 1.5 lbs (0.68 kg) and measures
3/4" x 1 ft. (19 mm x 30 cm). A narrow tag weight, 1/2" x 1 ft. (13 mm x 30 cm), weighing 0.65 lbs (0.30 kg), is also an option. Tag weights have tapered ends to minimize hang-ups during deployment and return to surface, and can be clipped on and off the cable or tape. This allows the use of the reel-mounted marked cable or tape for other uses.

Tape Guide

A Tape Guide is provided with each Tag Line. It can be placed over the top of the well casing for ease of use and to protect from damage on rough edges. It can also increase reading accuracies.
