Bürkert’s type 8750 flow controller system (FMR) is now being introduced into Australia and New Zealand. The 8750 flow controller system 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 8750 flow controller system is compact, reliable and robust for hard-working applications.  The unit is stand-alone, and requires no connection with remote devices with direct-entered process automation using local digital-display inputs. 8750 flow controller 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 8750 flow controller system is a complete system for the calculation and control of flow rates. The 8750 FMR system 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 8750 flow controller 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 8750 flow controller system is suited to air and gases as standard (liquid and steam media on request). Operating at 0ºC - 80ºC and to 16 bar pressure, the FMR is precise to ±3% which is considerably higher than the precision achieved with conventional pneumatic valve lines.

The 8750 flow controller system has been applied to successful conveying applications for solid products including roasted beans, chips, granulates, capsules, cohesive powders, briquettes, plastics, small parts, nuts, beads, pigments, powders, redispersable agglomerates, carbon prill, abrasive powders, salts, sand, sprayed granules and tablets.

The 8750 flow controller system is designed to act independently, and incorporates an automatic process tune for self-regulation and functionality. The 8750 flow controller system may be also controlled via integration with industrial network systems, including Profibus and DeviceNet.
