Water Gauges and Liquid Level Gauges WHAT IS A WATER GAUGE? A water gauge is a device that allows the liquid level in a vessel to be visually inspected. Water gauges are required by the ASME Boiler and Pressure Code on steam boilers, and are also useful in many other applications, such as monitoring the amount of oil in an oil tank. THINGS TO REMEMBER Care must be given to ensure the proper selection of a water gauge. Special attention must be given to temperature/pressure requirements and to the service media (i.e. water, steam, oils, chemical agents, etc.). Some items to keep in mind: • PRESSURE...

Water Gauges and Liquid Level Gauges 2. Select Non-Automatic, Automatic, or ASME Automatic: • use automatic (horizontally seating) or ASME automatic (vertically rising to seat in lower valve body) ball checks where available to minimize the risk of personal injury and/or property damage in the event of gauge glass breakage. The sudden rush of steam and water seats the balls, thereby shutting off the escape of steam and water. There will however be slight leakage as required by certain codes. 3. Select a handwheel style: • use aluminum handwheels for durability. • use plastic (composition) handwheels...
