What does a sprayer pressure gauge do?

• A. Monitors spray system by telling how much pressure is being used
• B. Measures flow rate to determine tank capacity
• C. Calculates chemical concentration in mix
• D. Regulates nozzle angles

Answer: (A)

A sprayer pressure gauge shows the current pressure in the spray line, telling you how hard the liquid is being pushed through the system. Keeping that pressure within the recommended range matters because it directly affects how much liquid exits each nozzle and the droplet size you achieve, which in turn influences coverage and drift control. The gauge helps you spot when the pump, hoses, or fittings aren’t delivering the right pressure so you can adjust accordingly. This isn’t measuring flow rate (that’s a flow meter), it doesn’t calculate chemical concentration (that comes from mixing/calibration calculations), and it doesn’t set nozzle angles (that’s done by nozzle selection and boom adjustments).
