Install a reliable water gauge from Grainger to help monitor the presence or the quantity of water in a tank, reservoir, or boiler feed. Standard pattern water gauges help provide liquid level verification for a wide variety of liquids. Choose a heavy pattern for higher service ratings. Automatic gauges have ball checks that can restrain fluids in the event the glass breaks. Gages with side-mounted hand wheels provide easier access in hard-to-reach places.
