Field of application

The Batch Controller RA33 is designed to record flow and control output signals for valves and pumps to ensure the exact dosing of predefined batch quantities. The measured volume can be corrected with the temperature/density compensation function. The filling process can be optimized with an automatic or fixed after-run correction. Mineral oils can be corrected according to the ASTM D1250-04 standard.

Recording and controlling of batch operations. Typical applications include:

  • Food industry

  • Chemical industry

  • Pharmaceutical industry

  • Oil & gas industry


  • Fixed and automatic after-run correction for constant, extremely accurate results

  • Higher quality through fast and exact dosing

  • Optional volume correction for mineral oils as per ASTM D1250-04

  • Detailed logging of protocols (preset counter, volume counter, batch name and number) as well as error messages and changes of operating parameters

  • Standard models are suitable for connecting and supplying all common flow transmitters, temperature sensors and density sensors

  • Remote control option to start and abort batch runs

  • Daily, monthly and annual statistics on the batch run size and quantity
