Moisture Meters

Our technology contributes to more efficient biomass processing in power plants, dehydration plants, and biomass processing plants worldwide.

Welcome to our Moisture Meter division

In today’s world, knowing the moisture value of biomass is of the utmost importance to processing it most effectively and thus increasing the yield, whether it be cellulosic 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 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 ensuring that the moisture value calculated is not based only on a small random sample.

When working with microwave-based moisture meters, it is important to consider reflections from the nearby environment, as they could disturb the measurements.

Apart from that, the moisture meter needs to know the biomass's volume and weight 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. Since then, we have developed and produced several models in our DSE4000 series, which are designed for 24/7 operation in industrial environments.

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

We maintain a high 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 before installing the moisture meter?

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

What types of materials are suitable to measure with microwaves?

You can use the microwave to measure 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 measurement result in percent of the material's volume and weight.

Are there any limitations to using a microwave-based moisture meter?

Limitations can occur if the material has a very small volume, a very high density, or a very long measuring distance. However, please feel free to contact us to discuss your moisture meter solution.
