Liquid level gauge

Broad view level gauge provides verification of fluid level in reservoirs. Nylon viewing area is 1 in. across and 3 to 36 in. long. Mounting flush to tank gives view from three surfaces. Upper and lower entry points of tank equalize atmospheric conditions within internal chambers, ensuring liquid level is at height of liquid in tank. Interchangeable bolts allow it to be built with shut-off valves (for removal without emptying tank) or a dial thermometer to monitor temperature.
