BURKERTS recently introduced Type 8750 Flow Controller system (FMR) offers a fully integrated and more precise method of pneumatic conveying of solids including grains, powders and granulated materials, and enhanced control for broader pneumatic conveying applications for the chemical, food and beverage, plastics and pharmaceutical industries.

The FMR is compact, reliable and robust. The stand-alone unit requires no connection with remote devices with direct-entered process automation using local digital-display inputs. 

The system will additionally integrate with a broader site multi-loop or fieldbus network, for centralised control.

Cost effective for moderate to high flow applications, the FMR is a complete system for the calculation and control of flow rates. It entails low operating costs and low air/gas consumption for economical performance. 

Gentle on the solid product being conveyed, with negligible abrasion or breakdown of the product, the 8750 FMR ensures minimal wear on piping infrastructure. 

Efficiencies are achieved via accurate continuous and precise control of the flow media (air), and accuracy in measurement of the solid product. The FMR system measures and controls volumetric flow rates on the differential pressure principle, using a smart control valve and two pressure transmitters (with optional temperature controller).

The pressure drop over the control valve, acting as a restrictor, is measured continuously via the pressure sensors. This pressure difference and the valve flow characteristics determine volumetric flow for the application. The measured volumetric flow is compared with setpoint and system parameters, with completely integrated real flow determination and control.

The FMR is suited to air and gases as standard (liquid and steam media on request).  Operating at zero to 80 degrees Celsius and to 16 bar pressure, the FMR is precise to plus or minus three percent which is considerably higher than the precision achieved with conventional pneumatic valve lines.
