A dispensing system includes a dispenser, a logic device, a nozzle, a diluent source, and a solid product. The logic device controls spray on and spray off cycles to pulse diluent supplied to the nozzle. The diluent contacts the solid product to dissolve a portion of the solid product and create a use solution. Pulsing the spray of diluent controls the concentration of the dispensed product in the use solution by limiting the amount of excess dilutant added to the dispensed product. The product is more consistently dispensed and the concentration of the dispensed product in the use solution is more consistent. Additionally, the concentration of the dispensed product in the use solution can be controlled by changing at least one of a volume of diluent dispensed through the nozzle, a pressure of diluent, a pulsed diluent spray frequency, and a pulsed diluent spray duration.

1. A dispenser comprising: a housing configured to hold a solid product;a timing device having an off state and an on state, the timing device configured to actuate supply of a diluent to the housing for a period of time when in the on state and thereby dissolve at least a portion of the solid produ
1. A dispenser comprising: a housing configured to hold a solid product;a timing device having an off state and an on state, the timing device configured to actuate supply of a diluent to the housing for a period of time when in the on state and thereby dissolve at least a portion of the solid product to form a solution;a reservoir in fluid communication with the housing and configured to hold the solution; anda measurement device configured to measure a condition at the dispenser and based on the condition measured at the dispenser cause the timing device to switch between the off state and the on state. 2. The dispenser of claim 1, wherein the measurement device comprises a level switch configured to measure a fluid level of the solution in the reservoir. 3. The dispenser of claim 2, wherein the level switch is configured to cause the timing device to switch from the on state to the off state when the fluid level of the solution in the reservoir is at a desired level. 4. The dispenser of claim 3, wherein the level switch is configured to cause the timing device to switch from the off state to the on state when the fluid level of the solution in the reservoir is at a lower level than the desired level. 5. The dispenser of claim 2, wherein the level switch comprises a float switch positioned in the reservoir. 6. The dispenser of claim 1, wherein the timing device is configured to prevent supply of the diluent to the housing when in the off state. 7. The dispenser of claim 1, further comprising a nozzle, and wherein the timing device is configured to actuate supply of the diluent to the housing for the period of time when in the on state by controlling the nozzle to pulse the diluent onto a surface of the solid product. 8. The dispenser of claim 1, wherein based on the condition measured at the dispenser the measurement device is further configured to cause the period of time that the timing device is configured to actuate supply of the diluent to the housing to change. 9. The dispenser of claim 1, wherein the measurement device comprises a load cell configured to measure weight loss of the solid product. 10. The dispenser of claim 1, wherein the measurement device comprises a conductivity cell configured to measure a concentration of the dissolved solid product in the solution. 11. The dispenser of claim 1, wherein the measurement device comprises a refractometer to measure a concentration of the dissolved solid product in the solution. 12. A dispenser comprising: a housing configured to hold a solid product;a timing device having an off state and an on state, the timing device configured to actuate supply of a diluent to the housing for a period of time when in the on state and thereby dissolve at least a portion of the solid product to form a solution;a reservoir in fluid communication with the housing and configured to hold the solution;a measurement device configured to measure a condition at the dispenser and based on the condition measured at the dispenser cause the timing device to switch between the off state and the on state; anda low product alarm device, the low product alarm device including an emitter, a receiver, and an indicator, the emitter configured to generate a beam, the receiver configured to receive the beam when the solid product no longer blocks the beam, and the indicator configured to output an indication when the receiver receives the beam. 13. A method of dispensing a solid product, the method comprising the steps of: supplying a diluent to a housing of a dispenser for a period of time, the housing holding a solid product such that supplying the diluent to the housing dissolves at least a portion of the solid product to form a solution;measuring a condition at the dispenser using a measurement device of the dispenser; andwherein based on the condition measured at the dispenser the measurement device causes a timing device to switch between an off state and an on state, and wherein the timing device controls diluent supplied to the housing for the period of time when the timing device is in the on state. 14. The method of claim 13, wherein measuring the condition at the dispenser comprises detecting a level of the solution in a reservoir that is in fluid communication with the housing. 15. The method of claim 14, wherein the timing device is switched from the on state to the off state when a desired level of the solution is detected in the reservoir. 16. The method of claim 15, wherein the timing device is switched from the off state to the on state when a lower level than the desired level of the solution is detected in the reservoir. 17. The method of claim 16, wherein the timing device prevents supply of the diluent to the housing when the timing device is turned off. 18. The method of claim 16, wherein the period of time that the timing device controls diluent supplied to the housing changes based on the detected level of the solution in the reservoir. 19. The method of claim 13, wherein the dispenser comprises a nozzle, and wherein the timing device controls diluent supplied to the housing for the period of time when the timing device is turned on by controlling the nozzle to pulse the diluent onto a surface of the solid product. 20. A method of dispensing a solid product, the method comprising the steps of: supplying a diluent to a housing of a dispenser for a period of time, the housing holding a solid product such that supplying the diluent to the housing dissolves at least a portion of the solid product to form a solution;measuring a condition at the dispenser;switching a timing device between an off state and an on state based on the condition measured at the dispenser, wherein the timing device controls diluent supplied to the housing for the period of time when the timing device is in the on state; andoutputting an indication at an indicator of a low product alarm device, wherein the low product alarm device is included at the dispenser and further comprises an emitter and a receiver, the emitter generating a beam and the receiver receiving the beam when the solid product no longer blocks the beam, and wherein the indication is output when the receiver receives the beam.
