AbstractA system is disclosed for independently attaining, monitoring, and dispensing a fluid mix or a plurality of fluid mixes of a desired temperature, flow rate, and volume, the fluid mixes each comprising two separate mixable fluids usually at different temperatures as they enter the system. The system comprises one microprocessor configuration connected with any number of fluid mixing apparatuses including their drive means, sensors, and an appropriate number of user command and system status feedback means. In one embodiment, as disclosed herein, a plurality of system users can independently and even simultaneously instruct, using a variety of means, a single microprocessor configuration to provide their desired fluid mixes. The microprocessor configuration compares the instructions with the system status data provided by the sensors and its own calculations. Whenever the data differs from the instructions, it causes the fluid mixing apparatuses' drive means to operate in such a way as to provide mixes which match the users' commands. Users are provided with system status information all the while.
