Notes on the problems we meet on site and how we approach them. Written for process and equipment engineers dealing with weight drift and wall-thickness deviation — not product advertising.
What a weight-per-meter control system actually does
Weighing, conversion, coordinated adjustment and repeat checking — the full signal path of a weight-per-meter control system, and how it differs from manual sampling.
Loss-in-weight versus gravimetric control: which one fits your line
Loss-in-weight and gravimetric systems do not measure the same thing. What differs, and the traps to avoid when selecting.
Weight per meter drifting? Seven causes, checked in this order
What to check first when weight per meter swings: material, feeding, screw and barrel, temperature, haul-off, and finally the measurement chain.
Choosing a weight-per-meter control system: 6 questions to settle first
The hard part is not the datasheet but what a supplier's "accuracy" figure actually means. Six questions that avoid most traps.
Is weight-per-meter control worth the investment?
Where material savings come from and how to estimate them — with the formulas, so you can judge the payback yourself.
What a weight-per-meter controller is, and how it differs from a control system
What the device consists of, where it sits, which signals it takes and what it computes, plus its limits and how to select one.
Weight-per-meter control across cable types: fibre, submarine, power and automotive
Fibre optic needs uniformity, submarine cable needs whole-length consistency, power cable hinges on insulation eccentricity, automotive cable changes construction most often.
What makes up a weight-per-meter control system quote
The six components of a quote, each explained, and why quotes for the same job can differ by a factor of two.
