6.2.6 Water Pump/Flowmeter Test
In order to achieve precise spray, the flowmeter and water pump should be
calibrated before use.
Before calibrating the water pump / flowmeter, check the spray system first. For
example, add 10L chemical into the chemical tank first, turn on the water pump, and
check whether the spray system works normally. If there is air bubble in the water
pipe, check whether the pipeline joint is loose. Then, check the exhausting function of
the solenoid valve. The pressure of spray system will be different if different
chemicals were sprayed. If the solenoid valve leaks water in the spraying process, it
can be solved by adjusting the regulator valve.
