Abstract
A fluid dispensing system for monitoring a weight of a fluid dispensed by a fluid dispenser. A first monitoring device determines a first flow characteristic, for example, pressure, of the pressurized fluid flowing through the fluid dispenser; and a second monitoring device determines a second flow characteristic, for example, viscosity, of the pressurized fluid flowing through the fluid dispenser. A monitor control produces an output representing a weight of the fluid dispensed by the fluid dispenser as a function of the first and second flow characteristics. The monitor control also stores values relating to a size of an orifice through which the pressurized fluid is dispensed and a density of the pressurized fluid. The weight value is determined as a function of the orifice size and the density values. The present invention also includes a method of monitoring a weight of a fluid being dispensed by a fluid dispenser.
