Level monitoring is a product category rather than a specific brand, encompassing various devices and systems used to measure and monitor liquid or solid levels in industrial applications. These products are offered by multiple companies across different countries. For instance, Siemens (Germany), Emerson (USA), and Endress+Hauser (Switzerland) are prominent manufacturers in this field. Level monitoring solutions serve industries such as oil and gas, chemical processing, water treatment, and food production. Key products include ultrasonic level sensors, radar level transmitters, capacitive probes, and float switches. These devices ensure accurate inventory management, process control, and safety compliance in industrial environments.
