First Claim
1. A fluid dispensing nozzle, comprising:
- a body;
a spout coupled with said body;
at least one fluid flow path disposed within said body, said at least one fluid flow path configured for fluid communication with a fluid dispensing hose;
an ultrasonic transducer disposed within said body and operatively coupled with said at least one flow path; and
control electronics in electronic communication with said ultrasonic transducer;
wherein said control electronics are operative to cause said ultrasonic transducer to transmit ultrasonic waves into said at least one fluid flow path;
wherein said ultrasonic waves are modulated at the time of transmission with information representative of a desired fluid flow rate.

Abstract
Systems and methods for regulating the flow rate of fluid at a fluid dispensing nozzle. In one embodiment, a nozzle includes a body, a spout coupled with the body, and at least one fluid flow path disposed within the body. The at least one fluid flow path is configured for fluid communication with a fluid dispensing hose. An ultrasonic transducer is disposed within the body and operatively coupled with the at least one flow path. Control electronics are in electronic communication with the ultrasonic transducer. The control electronics are operative to cause the ultrasonic transducer to transmit ultrasonic waves into the at least one fluid flow path. The ultrasonic waves are modulated with information representative of a desired fluid flow rate.

18. A method of regulating the flow rate of fluid at a nozzle in fluid communication with a fluid dispenser, said method comprising the steps of:
-
transmitting, from an ultrasonic transducer located in said nozzle, ultrasonic waves modulated at the time of transmission with information representative of a desired fluid flow rate, said ultrasonic waves propagating along a fluid dispensing hose extending between said nozzle and said fluid dispenser; receiving, at an ultrasonic transducer located in said fluid dispenser, said ultrasonic waves modulated with information representative of said desired fluid flow rate; demodulating said ultrasonic waves to obtain said information representative of said desired fluid flow rate; and adjusting at least one flow control component disposed along a flow path in said fluid dispenser based on said information representative of said desired fluid flow rate. - View Dependent Claims (19, 20, 21, 22)
