Level Gauge

A level gauge is an instrument used to visually measure and monitor the liquid or solid levels in tanks, vessels, and pipelines. Common types of level gauges include sight glasses, magnetic level gauges, and float-based gauges. These gauges are crucial for industries such as oil and gas, chemical processing, water treatment, and food and beverage, providing reliable and accurate readings to ensure safe and efficient operations, prevent overflows, and optimize resource use.
