Solid flow meter DYNAmas MF 5000 – Accurate bulk solids flow measurement is essential for maintaining stable production, reducing material losses, and improving process efficiency. However, measuring the mass flow of powders, dust, granules, and pellets in pneumatic conveying lines or free-fall processes remains challenging because conveying conditions can change continuously during operation.

The DYNAmas MF 5000 is an inline bulk solids mass flow meter designed for continuous, real-time measurement of dry bulk material flow. By determining material concentration and conveying velocity independently, the system continuously calculates the actual mass flow rate without interrupting production. This enables operators to monitor throughput, optimize process control, and improve production transparency across a wide range of industries.

What Is the DYNAmas MF 5000 Bulk Solids Mass Flow Meter?

The DYNAmas MF 5000 is an inline bulk solids mass flow meter that continuously measures the mass flow rate of dry bulk materials in pneumatic conveying systems and free-fall applications.

Unlike weighing systems that require interruptions or mechanical contact with the material, the DYNAmas MF 5000 performs continuous online measurement directly inside the process. The measured values are immediately available for monitoring, automation, and process optimization, allowing operators to react quickly to process variations while maintaining consistent product quality.

The system is designed for industries where accurate solids flow measurement directly affects production efficiency, material consumption, and quality control. Since measurements are performed continuously, operators no longer need to rely solely on manual sampling or periodic verification to estimate production throughput.

The DYNAmas MF 5000 is suitable for measuring many types of dry bulk materials, including:

• Powder
• Dust
• Granules
• Pellets
• Other free-flowing bulk materials

It can be installed in two common process configurations:

• Pneumatic conveying systems
• Free-fall material transfer

This flexibility allows the instrument to support numerous conveying and production processes without changing the overall process layout.

Why continuous inline mass flow measurement matters

Real-time measurement provides far more process visibility than periodic manual checks. Instead of discovering production deviations after a batch has finished, operators can identify changes as they occur and respond immediately.

Typical production benefits include:

• Continuous throughput monitoring
• Improved process automation
• More consistent dosing and batching
• Better production transparency
• Faster response to abnormal process conditions
• Reduced product losses caused by unstable conveying

For facilities implementing digital manufacturing strategies, continuous inline data also supports centralized monitoring and integration into modern process control systems, making production more transparent and easier to optimize over time.

How Does the DYNAmas MF 5000 Work?

The DYNAmas MF 5000 calculates mass flow by measuring material concentration and conveying velocity independently, then combining both values to determine the actual mass flow rate in real time.

Instead of estimating flow from only one process variable, the system separates the measurement into two independent components before performing the mass flow calculation.

This measurement concept allows the instrument to provide continuous online mass flow information without interrupting the conveying process. According to the DYNA overview, the DYNAmas uses capacitive measurement to determine product concentration and measures transport velocity separately before calculating the mass flow rate.

Capacitive measurement of material concentration

The first step is determining how much bulk material is present inside the conveying line.

The DYNAmas MF 5000 uses a capacitive measuring principle to continuously detect changes in material concentration as product passes through the measuring section. Because the measurement is performed continuously, concentration variations caused by changing process conditions are detected immediately.

This enables the system to produce stable measurement data for a wide variety of dry bulk materials, including powders, dust, granules, and pellets.

Independent velocity measurement

Knowing material concentration alone is not enough to determine mass flow.

The system therefore measures the conveying velocity independently from the concentration measurement. By treating these two variables separately, the instrument can accurately calculate throughput even when conveying conditions change during operation.

This independent measurement approach is particularly valuable in pneumatic conveying systems where conveying air velocity may fluctuate because of process adjustments, blower performance, or changing product characteristics.

Continuous mass flow calculation

After both values are available, the DYNAmas MF 5000 continuously calculates the actual mass flow rate and outputs the measurement for monitoring or process control.

The resulting data can be used for:

• Continuous throughput monitoring
• Process control
• Production optimization
• Material balancing
• Automated process adjustment
• Quality monitoring

Since the calculation is performed continuously, operators receive real-time process information instead of delayed production data.

Why is the DYNAmas MF 5000 independent from changing conveying velocity?

This is one of the key advantages of the DYNAmas measurement principle.

Many solids flow measurement technologies become less reliable when conveying velocity changes because they infer mass flow from a single measured parameter.

The DYNAmas MF 5000 follows a different approach by measuring:

• Material concentration
• Conveying velocity

independently before calculating mass flow.

As a result, changes in conveying speed do not directly distort the mass flow calculation, allowing the system to deliver stable measurements under varying conveying conditions. This independent measurement concept is one of the distinguishing characteristics of the DYNAmas product family for bulk solids flow measurement.
