New gauge reports moisture content via Bluetooth

The Austrian company Schaller is using Bluetooth to send users of chips and other biofuels speedy information about the fuel’s moisture content.
“The truck driver just fills this container with chips and the data reaches the user a few minutes later,” explains sales manager Wolfgang Hasenhütl.
This new technology presented at World Bioenergy in Jönköping, Sweden was developed in a project in the United States. The idea is that the sooner a user knows the fuel’s moisture content, the better they can optimise the logistics and combustion process.
Schaller specialises in measuring moisture content, and biofuels are a growing area of application. But merely having precise measuring equipment is not enough; what’s important is to take the measurements at the right points along the materials flow.
Where the right point is depends on the type of fuel. For chips, it can be out in the forest, before the material is loaded and driven to a power plant. For this purpose Schaller has developed a measurement unit made of stainless steel. The unit holds an instrument equipped with Bluetooth, the same type of communication technology found on wireless headsets for mobile phones.
“The truck driver fills the container with chips,” Hasenhütl explains. “The measurement readings are then transmitted to a computer in the truck and sent via mobile phone to the customer. That way the customer can direct the material to the correct place right away.”
The equipment has three different calibration profiles to suit varying types of fuel. It can also be recalibrated to work with most types of biomass.
