In-Line Moisture Meter for Biomass - UmiChip

A high-precision in-line moisture meter for biomass for fuel and other applications

What is the in-line moisture meter for umichip biomass?

The in-line moisture meter for biomass, umichip, is the Marrari solution for measuring the moisture in line for biomass and several other materials that pass on a conveyor or production line in real time. It has a sensor with active capacitive principle, i.e. the measurement is more accurate and faster than by resistance.

Why use umichip on my production line?

Why the measurement of the moisture of your material/product is essential to maintain the quality of it. For example: if the chip being transported via conveyor to the boiler for power generation is very humid, the boiler will have to evaporate the water before burning the chip and generate energy.

In this case above, the moisture meter in line, can determine the PCU (useful calorific power), if it is requested that this function comes included, ie: it shows in real time how much your boiler will produce energy with the material being transported!

How does umichip work?

It works via capacitativity, i.e. it is installed a sensor on the treadmill and while the material is loaded by it, it passes over the sensor and is read the moisture of the product second to second. So having a real moisture measurement.

How is umichip so accurate?

It uses a calibration method for recipes. In short: You use the Tracker (equipment that goes along with Umichip) that collects samples during the day and compares them with the laboratory.

If you have divergences, you can go to the included Tracker software and update the values to match the lab test, thus ensuring your accuracy.
