In-Line Volume and Moisture Meter for conveyorbelts and a variety of industry types of use
What is In-Line Volume and Moisture Meter VU?
The In-Line Volume and Moisture Meter, VU, is the junction between the products of the line MR600 volume X and MR700 umichip and its derivatives. Together they manage to give a range of information that will assist you in your production process to ascertain the quality of your material/final product.
Why should I use the VU on my line?
Because volume and humidity are crucial factors for maintaining the efficiency and quality of your product/material. Let’s take as an example the chip (biomass) for burning in boiler for power generation.
When the very moist chip is thrown in the boiler to burn, the boiler has to first evaporate the water (thus losing pressure) to then burns the chip and generate energy.
While the volume is important not to choke the boiler, because if you are playing too much material, you will be at risk of creating a lot of pressure and bursting the boiler.
How can the In-Line Volume and Moisture Meter VU be so precise?
The sensor for the volume is via laser and does not receive any interference of temperature, light or humidity when properly installed. And in addition, the accuracy is high, with a margin of error of only 3%.
Already the moisture part, works via capacitativity, that is, a sensor is installed 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.
And what other resources does it offer for management?
The volume part also accompanies several performance features such as OEE, where you can view second to second, the downtime and operation of your machine, operator uptime, material quality, and it still issues emails and alerts if you have Some problem with the production. By joining these three factors you will have the efficiency index of that production or line.
While the moisture part is able to keep track according to the second the actual humidity, it can also be corrected according to laboratory tests.
And why use the Marrari equipment?
Because our equipment is optimized for your company! We create ways to improve the performance of production processes without excessive loss using methods such as OEE and Industry 4.0. Thus creating a more efficient, productive and modern production environment!

Static accuracy: better than 3% depending on the grain size of the material.
Calibration: Extremely simple, using a sample of material with known volume or by volume simulation using a body of known dimensions.
Calibration frequency: under usual conditions of handling of wood chips the calibration frequency is around six months.
Mounting: is made in the form of a bridge, over the conveyor. The supports are adjustable depending on the width and carrier structure of the conveyor. It does not require mechanical changes in the conveyor, nor does it require special roller or roller replacement.
Models: low cost options for low capacities, high precision scanners for treadmills up to 600mm and scanners for treadmills up to 5m wide.
Principle of operation: The Umichip system is based on the analysis of the dielectric properties of the medium and correlates them with the moisture content of the material. In each transducer a processor continuously performs the measurements and every second dozens of readings are made. The result, after analysis, is sent to the central unit where they are correlated with the calibration curve corresponding to each material.
Calibration: The calibration of the system is done in-line, comparing the values read by the UMICHIP system with the values obtained in the laboratory.
Calibration frequency: It will be necessary to calibrate the system whenever the material in process is modified. For each material a calibration curve will be created that will remain in the system memory (up to 100 recipes).
