Matherne Instrumentation’s wireline weight indicator systems are designed to provide accurate measurement of downhole tool weight during wireline operations and heel or floor block applications.
Ideal for use by wireline service trucks for measuring the amount of tension on wireline when logging tools, perforation guns, downhole explosives, or when survey tools are lowered or pulled out of the hole.
The system includes a 6” wireline weight indicator with bracket, hose, and tension load cell or tension cylinder.
In heel or floor block applications, the tension loadcell is provided with two eyes: one at the top to attach to the floor block, while the other at the bottom to attach to the Christmas tree or derrick floor, forming a pull at 90°. The system is calibrated to this right angle pull. Accuracy will be slightly affected if this angle is not true, but the sensitivity is always maintained. The convenient mounting design allows the gauge to be mounted in the service truck, unit console, or stand alone.
