Moisture Meters

Our technology contributes to more efficient processing of biomass in power plants, dehydration plants and biomass processing plants all over the world.

Welcome to our Moisture Meter division

In today’s world, knowing the moisture value of biomass is of the outmost importance in order to process the biomass most effectively and thus increase the yield, may it be cellulossic ethanol production, dehydration of animal feed, energy production, pellet production or other applications.

Moisture Meter working principle

Our Moisture Meters are suitable for any biomass and
are used in many different applications.

Moisture Meter system

The technical principle is based on microwaves being transmitted through the bale of biomass from one side to the other thus measuring a large amount of material, and hereby ensuring that the moisture value calculated is not only based on a small random sample.

Then working with microwave based moisture meters it is important to consider reflexions from the nearby invironment as they could disturb the measurements.

That apart - the moisture meter need to know the wolume and the weight of the biomass in order to relate the measuring results to the specific biomass being measured.

Moisture Meter models for different applications

We installed our first Moisture Meter The DSE4100 in 1992 at the energy company Dong and have since develloped and produced severel models in our DSE4000 series, which are developed for 24/7 operation in industrial environments.

  • The DSE4130 - a new generation of the DSE4100 - is used for crane applications and measuring bridges for trucks.
  • The DSE 4101/4111 is used for conveyer application e.g. measuring dehydrated Alfalfa.
  • The DSE4200 is used for baler applications then the biomass is being baled in the field.

We try to maintain a high level market position in this area through our participation in research projects and extensive development and installation of standard measurement solutions.

We are here when you need us

Our many specialists are happy to provide expert consultation and assistance for any questions regarding moisture measurement in biomass.


What are the advantages of a microwave based moisture meter?

When measuring with microwaves you are in contact with a lot of material instead of just a little sample. You get the measuring result at once. And you get a very accurate result.

Are there any issues to consider then installing the moisture meter?

All you have to consider is no metal between Transmitter and receiver and also that the sensors are in parallel.

What types of material are suitable to measure with microwaves?

Microwave can be used to measure in all organic materials.

How does a microwave based moisture meter work?

The transmitter sends a signal of a known power through the material. Then the microwaves encounter water molecules, the oscillation of the water molecules makes the signal lose power and the weakened signal can thereafter be calculated into a moisture measuring result in percent% of the volume and weight of the material.

Are there any limitations then using a microwave based moisture meter?

There can be limitations if the material is of very little volume or if the density of the material is very high or if the measuring distance is very long. But please feel free to contact us and we will advise you about a moisture sensor solution to your project.
