Where should a properly installed flow meter be located in a large volume sprayer system?

A flow meter in a large volume sprayer system is best located near the pressure regulator. This position is critical because it allows for accurate measurement of the flow rate of the liquid as it moves through the system at the point where the liquid is regulated for pressure.

By placing the flow meter after the pump and before the nozzles, you can ensure that the readings reflect the flow rate under the specific pressure conditions set by the regulator. This information is vital for maintaining the desired application rates and ensuring the effectiveness of the pesticide application.

Locating the flow meter near the pump could lead to fluctuations in the reading due to changes in pressure or pump output variability. Similarly, positioning it near the nozzles might result in inaccurate measurements caused by pressure losses in the system or variations due to nozzle characteristics. Therefore, positioning the flow meter near the pressure regulator provides the most reliable data for ensuring consistent application rates during operation.
