Abstract: A tube holder is disclosed for use in a system for transferring fluid products from a container via a continuous flexible tube. The tube holder is a lightweight, relatively rigid support having a length corresponding to the length of the container, and a substantially C-shaped cross section so that the tube easily snaps into the support. These supports can be produced using extruded PVC. The tube holder also preferably includes a sleeve member at one end for retaining the tube. To facilitate identification of which tubes are to be used with various different chemicals, a multiplicity of differently colored sleeve members may be provided.

Abstract: A low level indicator and warning device is provided wherein a diaphragm is provided directly in a line for drawing liquid from one container to another. Liquid flowing in the line washes directly across the diaphragm so that it remains clean and thus operative even in the presence of materials which might form a crust on the diaphragm.
