TEWS High Performance Solutions

Food & Petfood Industry As a Partner.

Your production process combined with our patented solutions. The result: the most accurate data about the residual moisture & density of your products.

Solutions that help companies to achieve their goals faster. For over 30 years TEWS moisture & density measurement solutions are worldwide in use in the food industry. Our high-performance solutions combine surface and core moisture detection as well as density measurement based on patented TEWS microwave technique.

Measurably better - No matter whether it is about green or roasted coffee, cocoa, cereals, oil seeds, gelatin, soft candy, snacks, pasta or nuts, our high-performance solutions are simple: we provide patented microwave measurement technology tied to passion driven services. Why all that? The answer is as simple as our solutions: to improve the production process of our clients. Or, in other words: to help our clients to achieve better results.

Our solutions have been developed and designed hand-in-hand together with the food industry and, therefore, fulfil all requirements in terms of food-grade-material.

The TEWS method enables food companies to gain high-precision data about the level of moisture content and density of their products. It’s a one-stop-shop without any sample preparation to optimize the whole production process in terms of cost savings and quality control.



savings – due to improved dryer control



faster –in the lab due to readings within milliseconds



control – of finished products like soup cubes

How Leading Companies Benefit From TEWS.


Water Matters.

Product quality and -efficiency can be significantly optimized by controlling the moisture content in almost all process steps. Managing the moisture of food and its ingredients is a key factor to achieve better results. TEWS patented solutions deliver high precision results. It's what matters when it comes to company goals and how to achieve them faster.


  • Fast Inline Measurement – The continuous moisture measurement helps to cope with changing ambient process conditions and there is no need to wait long time on the results of spot checks.
  • Product Quality – A precise moisture level is often decisive for the taste. And that, in turn, has an impact on the purchase decision of the end consumer.
  • More Profit – Precise data of water content lead to precise prices.
  • Energy Efficiency – Precise information about moisture allows optimization of drying processes, prevents overdrying and leads to lower energy costs.
  • Storage Efficiency – Precise compliance with the recommended water content prevents mold, avoids fungal infection or early degeneration and increases shelf live.

It Takes Two.

TEWS patented two-parameter measurement solutions enable food producing companies to work with precise data in both ways at the same time. Data that relate to the moisture content of food and its ingredients as well as its density. Knowing the bulk density of food during the manufacturing process leads to even better results in terms of product quality and -efficiency.


  • Mass Flow and Balance Check – Accurate density information being used to assure constant filling levels e.g. in bags and to avoid overfilling or to heavy products.
  • Plant Efficiency – Fully automatic filling control of boxes and cartons up to 250 kg without manual efforts.
