Liquid Level Gauges and Sight Indicators

Help maintain liquid levels with liquid level gauges and sight indicators from Grainger. Choose from a selection of full-view and window sight flow indicators that let you view the presence or clarity of liquids in a piping system or liquid level in a tank. They allow you to monitor chemical processes occurring in your equipment, and help detect leaks, flow interruptions, and contaminants. The design provides a 360° viewing area with no corners to collect debris. Gauge cocks are valves designed for placement on either side of water gauges to isolate the gauge chamber from the liquid contents of the vessel. They help prevent rapid loss of fluid from accidental glass breakage and are for use where liquid level monitoring is required. Some gauge cocks have an automatic ball-check shutoff that helps prevent rapid fluid loss from accidental glass breakage. Water gauges are available in various pipe sizes, body materials, max. pressures, and max. temperatures for a variety of applications.
