Application
The RA33 batch controller records flow rates and controls valves and pumps via output signals, ensuring that the preset batch quantities are dosed accurately. The measured volume can be temperature/density compensated. The filling process can be optimized by automatic or fixed post-run correction. Mineral oils can be corrected in accordance with the ASTM D1250-04 standard.
Used for recording and controlling slow batching operations with a duration of more than 10 seconds. Typical applications include the following industries:
Food industry
Chemical industry
Pharmaceutical industry
Oil and gas industry
Benefits
Automatic or fixed post-run correction for stable, high-precision measurement results
Fast and accurate batching for improved control quality
Optional correction of the mineral oil volume in accordance with the ASTM D1250-04 standard
Detailed job logging (preset counter, volume totalizer, batch name and number) as well as error messages and changes in operating parameters
Standard mode for connecting and servicing all common flow transmitters, temperature sensors and density sensors
Optional remote control for starting and terminating batch runs
Daily, monthly and annual statistics of batch run scale and quantity
