Hydraulic Bench Unit

An integral weir tank is provided along with a volumetric measuring tank which is stepped to afford accurate measurement of both high and low flow rates. The Hydraulics Bench Unit range provides the basic services for pumping and volumetric measurement of the water supply with which all the additional accessories and experiments are used. The measuring tank discharges into a fiberglass sump tank by means of a quick acting ball valve. The working surface of all three units is molded in fiberglass and provides a recessed area on which to mount experiments.
