What Is a Solids Velocity Meter or Velocity measurement?
A solids velocity meter is an industrial instrument that continuously measures the conveying velocity of bulk materials moving through pneumatic pipelines or free-fall systems. Unlike conventional sensors that estimate flow conditions indirectly, a solids velocity meter measures the actual particle velocity, providing accurate process data for monitoring and control.
In many bulk material handling systems, conveying velocity directly affects product quality, energy consumption, pipeline wear, and production stability. Measuring velocity enables operators to optimize conveying conditions while providing one of the key variables required for continuous mass flow measurement when combined with a solids concentration sensor.

How DYNAvel Works
DYNAvel measures solids velocity using a non-contact absolute transit time measurement principle, providing continuous real-time data without requiring calibration or direct contact with the material.
Unlike mechanical or contact-based sensors, DYNAvel does not rely on moving parts or physical interaction with the conveyed product. Instead, the system analyzes the movement of bulk solids as they pass through the measuring section, enabling reliable velocity measurement across changing operating conditions.
The measurement process can be summarized in four steps:
- The sensor continuously detects the movement of bulk solids inside the conveying line.
- The system calculates the particle velocity using an absolute transit time measurement method.
- Automatic signal adaptation compensates for changes in material density and conveying conditions.
- The measured velocity is transmitted in real time to the plant control system for monitoring and process optimization.
This measurement principle offers several practical advantages over conventional technologies:
- No contact with the product stream.
- No mechanical wear.
- No routine calibration.
- Stable long-term measurement accuracy.
- Continuous online monitoring.
- Reliable performance across a wide density dynamic range.
The real-time velocity data can also be combined with a solids concentration measurement system to calculate continuous mass flow. This provides operators with a more complete understanding of the conveying process and supports tighter production control.
For system integration, DYNAvel communicates through CAN-Bus and 4–20 mA analog output, allowing straightforward connection to existing PLC and SCADA systems. Multiple measuring points can be integrated into the same monitoring architecture, making the solution suitable for both individual conveying lines and larger plant-wide installations.
By continuously measuring actual conveying velocity instead of estimated airflow, DYNAvel gives engineers actionable process data that can be used to optimize blower settings, reduce energy consumption, improve conveying efficiency, and maintain stable operating conditions throughout the production process.
