Designed to withstand the harsh working environments of slickline operations, WMS is built from lightweight, high tensile, aerospace grade, anodised aluminium and offers a simple retrofit solution.

Highly accurate load monitoring

Use WMS-slickline at the hay pulley to accurately show small downhole weight changes. By inputting a K-factor WMS can also provide cable angle compensation and indicate actual downhole weight change in real-time.

Data displayed to a zone 1 hand held, battery powered display or analogue gauge. Available for any capacity including 1,000 to 10,000 pounds.
