Liquid Level Gauges and Sight Indicators

42 products
Liquid level gauges and sight indicators let users see the level, flow, clarity, and color of liquids in a container or system. Full-view and window sight-flow indicators show the presence or clarity of liquids in a piping system or liquid level in a tank. They are used to monitor chemical processes occurring in equipment and to detect leaks, flow interruptions, and contaminants in a system. Gauge glasses and water gauges are used to monitor fluid levels. Gauge cocks are valves that are placed on either side of glass gauges to isolate the gauge chamber from the liquid contents of the vessel. They have an automatic ball-check shutoff valve that helps prevent rapid loss of fluid if the gauge glass accidentally breaks.
