July 2009, Celulosa Arauco purchases two LOGMETER® 4000 systems Celulosa Arauco S.A. purchased two new Logmeter® 4000 systems, one for its Constitución Mill and one for its Valdivia mill. Both mills are already familiar with Logmeter® systems, as they have been using Logmeter® 4000 predecessors for more than 10 years. In addition to the measurement of solid volume, the Logmeter® 4000 units will provide the ability to measure the volume of chip and biomass loads in container trucks. The system also includes a comprehensive auditing system, which stores all results, 3D images, and photos for later revision. Back
