The in-line measurement of bulk solids flow is important for product quality, process efficiency and system safety. The Ramsey Granucor Solids Flow Measurement System from Thermo Fisher Scientific provides continuous, real-time flow measurement of free falling materials or dense phase, pneumatically conveyed bulk solids. Its non-intrusive design and patented software can be used to monitor and control the flow in pipes or the flow distribution through pipe networks.

The complete system can measure and output:

• Bulk Flow Rate 
• Totalized Flow
• Concentration 
• Velocity

Applications

The Ramsey Granucor Solids Flow Measurement System is ideal for measuring mechanically conveyed plastic pellets and pneumatically conveyed solids in coal-fired blast furnaces. In blast furnaces, the system can be used to balance feed among the tuyeres, improving blast furnace efficiency, as well as iron quality and consistency. It can also be used to measure the flow of plastic granules in injection molding facilities or pelletizers, and to control the flow of various additives.

Capacitance Flow Measurement

A complete Ramsey Granucor Solids Flow Measurement System is composed of two independent sensors and a correlator/integrator. The Ramsey DK13 Velocity Sensor and the Ramsey DC13 Concentration Sensor operate using capacitance technology and are designed for direct installation into process piping. The Ramsey DC13 Concentration Sensor measures the change in capacitance with material present versus the capacitance of an empty pipe. This change in capacitance is proportional to material concentration. The Ramsey DK13 Velocity Sensor uses two measuring points and a technique known as cross-correlation to measure the time it takes for the material to travel between the points. Both of the sensors’ measurements are then output to the Ramsey Micro-Tech 2109 or 3109 Correlator/Integrator, which calculates the mass flow rate.
