It is important to check nozzle output frequently even if you do not change the spray rate.

It is important to check nozzle output frequently even if you do not change the spray rate.

• A. True
• B. False
• C. Only When Changing Nozzles
• D. Only When Calibrating

Answer: (A)

Even with a fixed spray rate, nozzle output can drift over time due to wear, clogging, or changes in pressure. Nozzles wear at the orifice, tiny blocks can partially close a hole, and damaged seals or fittings can alter how much liquid is delivered. Pressure changes in the system can also change actual flow even if the rate setting remains the same. Checking nozzle output regularly, by measuring the actual volume each nozzle delivers over a set time at the operating speed and pressure, helps ensure every nozzle is producing the intended amount and pattern. If a nozzle is delivering too little or too much, it should be repaired or replaced to maintain uniform coverage and stay within label requirements. So the statement is true: frequent checks are important regardless of whether you change the spray rate.
