A pulley assembly includes an elongate pulley hanger, supported at the upper end of a pillar rising from and dependently supported by a base bracket, and first and second pulleys slidingly supported by the pulley hanger. The base bracket securely mounts the pulley assembly to the top of a liquid storage tank. Each provided pulley implements, or is otherwise provided with, a clamp, whereby each pulley is readily positioned along the pulley hanger, and, when in a desired position, easily and securely fixed in the desired position.

A liquid level indicating device includes a moving member which is arranged in a liquid tank storing a cooling liquid and moves vertically in conjunction with variation in a liquid level of the cooling liquid, a string member having one end portion connected to the moving member, the string member being configured to be bendable and non-extendable in a longitudinal direction, an indicator connected to the other end portion of the string member and which indicates a height position of the moving member as a remaining amount of the cooling liquid by operating in conjunction with movement of the moving member through the string member, and a tube member which is configured to be bendable and non-extendable in the longitudinal direction, has the string member passed therethrough, and connects the liquid tank and the indicator.

A liquid level gauge has a scale, a first float, a second float, a first level indicator, and a second level indicator. The scale is positioned on a sidewall of a storage tank containing two liquids. The first float is positioned in the tank and weighted to maintain buoyancy on the surface of a first liquid. The second float positioned in the tank and weighted to maintain buoyancy on the surface of a second liquid. The first level indicator is suspended adjacent the scale and connected to the first float to be responsive to changes in the level of the surface of the first liquid. The second level indicator is suspended in the level indicator cover vertically below the first level indicator and connected to the second float to be responsive to changes in the level of the surface of the second liquid.

An assembly and method for the measuring of fluids in a tank. The assembly uses a fluid measuring system to measure and indicate the fluid levels inside the tank. The assembly creates a sealed unit that couples to the tank and external gauge so as to stop the venting of gas to the atmosphere. The assembly may include the tank and external gauge in selected embodiments. The assembly can function without the use of electronic measuring and reporting devices.
