Quantitative control instrument is a flow measurement and control system based on ARM microprocessor, combined with various flow transmitters, sensors (such as turbine, vortex street, electromagnetic flow meters, etc.), and electromagnetic valve pump bodies. It can accumulate flow and control quantitative flow. The quantitative control instrument has a good human-machine interface and soft and hard protection measures, which is easy to operate, reliable in safety performance, excellent in anti-interference performance, and excellent in stability performance. It is mainly used in industries such as petroleum, chemical, pharmaceutical, and food that require quantitative packaging and control: quantitative feeding/feeding, loading, batching, discharging, dividing, and adding gas.
