Can be used for all types of liquids except for viscous and slurry-like substances. Simple installation and usage.<\/li>\n\n\n\n<li><strong>Disadvantage<\/strong>: Outdated technology. Prone to damage after a short period of use due to the float being prone to getting stuck, leading to incorrect signal readings.<\/li>\n<\/ul>\n\n<h4 class=\"wp-block-heading\"><strong>3.1.2 Capacitive Liquid Level Sensors:<\/strong><\/h4>\n\n<ul class=\"wp-block-list\">\n<li><strong>Advantages<\/strong>: Can be used in applications with high pressure and temperature. Low cost. Minimum liquid level measurement distance is 100mm. The sensor is suitable for harsh environments such as high temperature and pressure. Capable of measuring fuel, oil, integrated with explosion-proof features.
