A fluid flow indicator system for fluid-dispensing nozzles including a fluid passage, a sensor in communication with the fluid passage, a control in electrical communication with the sensor, a power source in electrical communication with the sensor and the control, and at least one indicator in electrical communication with the control and actuable under at least one predetermined fluid condition. The sensor measures a fluid condition in the inlet of the fluid passage and generates a corresponding output signal. The control processes the output signal from the sensor, compares the output signal with predetermined fluid condition threshold ranges, each predetermined fluid condition threshold range representing a corresponding level of fluid condition, determines the corresponding level of fluid condition, and actuates the indicator corresponding to the predetermined fluid condition to allow a user of the fluid-dispensing nozzle to perceive an indication of the level of fluid condition. |
