A control system for controlling operation of a fluid delivery system that includes a first and second pumps for delivering first and second fluids for mixing. A controller includes a first pump map having a first pump flow rate mapped against a control output signal, and a second pump map having a second pump flow rate mapped against a control output signal. The controller determines the control output signal for the first pump to obtain a desired flow rate from the first pump, and the control output signal for the second pump to obtain a target flow rate and a target percentage of the second fluid relative to the first fluid or a target percentage of the second fluid relative to an overall fluid flow. The output signals for the first and second pumps are determined using the first and second pump maps.

A fluid circulation monitoring system includes a distributed processing system having a first processor located on-premises near a space filled with a circulating fluid and a second processor located off-premises.

A sensor is operatively connected to the first processor and senses at least one parameter associated with a flow rate of fluid through the circulation system. The distributed processing system is configured to process the at least one parameter and derive a volumetric fluid flow rate through a fluid pump which propels the fluid through the circulation system. Pattern recognition is applied to the at least one parameter to detect maintenance events and predict the need for maintenance events.

A system, method and device for mass airflow sensor signal processing includes a microcontroller, a mass airflow sensor and an engine PCM. An analog-to-digital converter (ADC) converts a first output signal from the mass airflow sensor to a first V.sub.DC value. A digital-to-analog converter (DAC) converts a second V.sub.DC value to a second output signal associated with the mass airflow sensor. Transfer functions are obtained from a flow bench using the mass airflow sensor, performance air intake components, and stock air intake components. The microcontroller determines, from the first V.sub.DC value, a corresponding actual flow rate. From the actual flow rate, a corresponding stock V.sub.DC value is determined. The stock V.sub.DC value is then output to the DAC for conversion to the output second signal associated with the mass airflow sensor for communication to the engine PCM.
