In modern industrial production, level instrumentation has become a crucial component for ensuring safety management, production efficiency, and cost control. Whether monitoring liquids, slurries, powders, or bulk materials, precise and reliable level measurement is essential to maintain stable and safe operations. As a national high-tech enterprise, Jiwei Automations provides a complete range of level instrumentation solutions, from continuous measurement to point-level alarms, covering radar, vibrating rod, tuning fork, RF admittance, and rotary paddle technologies. Our solutions are independently developed by Jiwei Automations, delivering smart, high-reliability, and industrial-grade monitoring for complex applications.
Challenges in Industrial Level Instrumentation
Industrial environments often present extreme conditions, including high temperatures and pressures, heavy dust, corrosive liquids or slurries, steam, and foam interference. Additionally, variations in material types—liquids, slurries, powders, and bulk solids—affect continuous measurement accuracy and point-level alarm reliability. Continuous 24/7 production requires instruments that are highly stable, low-maintenance, and compliant with explosion-proof, corrosion-resistant, and other safety standards. Combining high-precision continuous level instrumentation with reliable point-level switches and intelligent monitoring systems is essential to ensure safe production, optimize efficiency, and reduce operational risks.
