Calibrate Flowmeter—Liquid Catch Test

Always fill solution tank with clean water before performing a calibration test.

Ensure that control valve and rate sensor are configured before performing a calibration test.

Catch Test allows operator to collect product from up to seven samples and enter exact amounts collected to calibrate flowmeter. Place containers (such as calibration containers) under the nozzles to capture the product sprayed during test. If all the nozzles require testing, repeat the Flowmeter Calibration as many times as needed. By measuring these samples and entering the values into system, an accurate flowmeter calibration value is determined.
