Teqwave H from Endress+Hauser is designed for food and beverage producers who require continuous inline concentration measurement without time‑consuming sampling. Installed in pipes or tanks, it measures liquid concentration directly in the process and helps maintain consistent product quality by enabling fast reaction to deviations while reducing operational effort.
In hygienic food and beverage production with varying raw materials and changing recipes, Teqwave H provides continuous process insights at critical measurement points. Real‑time concentration monitoring supports stable process operation and early detection of deviations, helping to maintain reproducible product quality. By reducing manual sampling and laboratory analysis, inline measurement simplifies daily operations and improves overall process efficiency.
Benefits
Stable inline quality control – continuous quality information directly from the main process flow
Reduced sampling and laboratory effort – minimized manual sampling and faster availability of quality data
Consistent product quality – reproducible quality across changing batches and recipes
Early detection of process deviations – timely corrective action before off‑spec production
Reliable hygienic operation – designed for Food & Beverage applications with strict hygiene requirements
