Abstract: A sensor mount is disclosed for use in a fluid volume measurement structure forming part of a fluid measurement system for feeding fluid in controlled amounts. The sensor mount includes a tubular body having first and second sensor mounting sockets whereby functionally different fluid sensors may be mounted to the tubular body. As fluid enters or exits the tubular body, a fluid sensor mounted in one or the other of the sensor sockets produces a signal to be used by a control portion of a fluid measurement system. The first sensor socket is provided as a through hole whereby a sensor may be mounted in fluid contact with the interior of the tubular body. The second sensor socket is provided as a blind hole for receiving a capacitance sensor out of fluid contact with fluids within the tubular body.

Abstract: A vertically mountable sight gauge is comprised of one or more serially connectable sections for visually determining the level or the volume, or both, of liquid stored in a container. Each section has an upper and lower housing. Each housing has a passage therethrough with a first end and second end, is surrounded by a flange, and is attached to the ends of a straight length of substantially transparent, flexible pipe. The pipe is surrounded by a cylindrical, substantial transparent, rigid shield and a cylindrical, substantially transparent, rigid sleeve. The bottom end of the sleeve is surrounded by a shoulder. The outer diameter of the top end of the sleeve is less than inner diameter of the shield, such that the sleeve telescopically engages the shield. Biasing means bears against the bottom end of the shield and the sleeve's shoulder, surrounds and overlaps the sleeve, and urges the shield against the upper housing and the sleeve against the lower housing.
