1. A transfer mechanism for transferring a fluid processing reservoir from a support so that the volume of liquids in the reservoir can be estimated in use, the mechanism comprising:
a weighing member comprising a hook and a load cell, wherein the hook is operationally supported by and positioned below the load cell; and
a front carriage comprising an extension moveable by an actuator, the extension pushing the front carriage in a forward direction toward the reservoir and pulling the front carriage in a rearward direction away from the reservoir, the front carriage collecting the entire reservoir in the forward direction and hanging the entire reservoir on the hook of the weighing member as a result of moving in the rearward direction;
wherein the weighing member is configured to allow the reservoir to hang freely below the hook, such that the weighing member is effective to measure an in-use weight of the reservoir via a force applied to the load cell when the reservoir is hanging freely below the hook.
