Level Gauges are essential instruments used to measure and monitor liquid levels in tanks, vessels, and other containers across industrial applications. These devices ensure accurate level detection, critical for process control, inventory management, and safety in industries like chemical processing, oil & gas, water treatment, and manufacturing. Common types include sight glasses, magnetic level gauges, and ultrasonic level sensors. Sight glasses provide visual confirmation, magnetic gauges offer reliable readings in harsh conditions, and ultrasonic sensors deliver non-contact measurements. Key features often include corrosion resistance, high-pressure tolerance, and compatibility with various fluids. Level gauges may integrate with automation systems for real-time data logging and alerts.
