Abstract
A system can include a solenoid manifold including a plurality of solenoid valves to control fluid flow between a tube and a plurality of nozzles, wherein one end of the tube is connected to a pump and the other end of the tube is connected to an inlet of the solenoid manifold; and a controller programmed to determine whether at least one solenoid valve of the plurality of solenoid valves is incorrectly in an open position based on pressure measurements representing a fluid pressure within the tube.
Claims20
A system comprising:
- a solenoid manifold including a plurality of solenoid valves arranged to control fluid flow between a tube and a plurality of nozzles, wherein one end of the tube is connected to a pump and the other end of the tube is connected to an inlet of the solenoid manifold;
- and
- a controller programmed to determine whether at least one solenoid valve of the plurality of solenoid valves is incorrectly in an open position based on pressure measurements representing a fluid pressure within the tube.
A system comprising:
- a solenoid manifold including a plurality of solenoid valves arranged to control fluid flow between a tube and a plurality of nozzles, wherein one end of the tube is connected to a pump and the other end of the tube is connected to an inlet of the solenoid manifold;
- at least one sensor that measures fluid pressure within the tube;
- and
- a controller programmed to determine whether at least one solenoid valve of the plurality of solenoid valves is incorrectly in an open position based on pressure measurements representing a fluid pressure within the tube.
A system comprising:
- a solenoid manifold including a plurality of solenoid valves arranged to control fluid flow between a tube and a plurality of nozzles, wherein one end of the tube is connected to a pump and the other end of the tube is connected to an inlet of the solenoid manifold;
- an ultrasonic transducer mounted to an external surface of the tube that generates ultrasonic signals and measures reflected ultrasonic signals;
- and
- a controller programmed to determine whether at least one solenoid valve of the plurality of solenoid valves is incorrectly in an open position based on the reflected ultrasonic signals representing a fluid pressure within the tube.
