Digester

Point LevelPressure
Digester

Overview

In the digester, the action of chemical dissolution removes the lignin binder, thereby exposing and freeing the cellulose fibres. During the cooking process according to the alkaline sulphate method, the fibres are fed into the digester by means of steam pressure. To enable fully automatic operation of the digester, a point level detection of the filling is required. The vessel pressure also needs to be carefully monitored throughout this process.

Inventory System

VEGA Inventory System (VIS) is a web-based software for real-time data acquisition, visualization, and logistics management of inventory levels in storage tanks and silos. Companies can manage their inventories proactively, ensuring greater flexibility in delivery schedules, expanding optimization options, and reducing stock discrepancies. Precise, real-time visualization of stocks allows deviations to be quickly identified, minimizing financial impact. The system combines reliable VEGA measurement technology for liquids and bulk solids with secure cloud-based or on-premises software, providing the basis for intelligent and strategic decisions for optimal inventory management. VIS supports both internal inventory monitoring and Vendor Managed Inventory (VMI) applications, where suppliers manage customer stock replenishment using real-time level data.

  • Real-time inventory monitoring across all connected storage locations via web browser or mobile app
  • Four visualization modes — Chart, Graphic, Map, and Trend — for comprehensive stock visibility
  • Color-coded traffic light status system (green/yellow/red) for instant stock level assessment
