Keeping air under control

摘要

Tessenderlo Chemie produces dicalciumphosphate at its production facility in Ham, Belgium. Recently, a flat-operated flow meter was replaced with a thermal dispersion flow sensor, a move claimed to simplify the acquisition of preventative indications. Alfons Calders, of Industrie Technisch Management, explains how. The chemical conversion takes place in high silos, in which an air stream keeps a mixture of sand and hydrochloric acid moving. To make sure the blowers, that manage the inlet, were supplying sufficient flow a mechanical meter was used to test the flow on the pipe.
