Abstract
A fluid dispenser for measuring precise volumes of a fluid for later mixing with other materials which has a pressure vessel for receiving a fluid supplied from a supply tank, a bubbler sensor communicating with the pressure vessel for correlating pressure within a bubbler tube with volume in the pressure vessel so that a controller in communication with the bubbler sensor can control the inflow and outflow of precise volumes of the fluid through the pressure vessel. The bubbler robe is received within the pressure vessel and is monitored by a pressure transducer which communicates with the controller so that a plurality of solenoid valves can control the inflow and outflow of the measured fluid.
