![]() After you put the fogger into service, use actual data on liquid consumption and fogging times to refine your calibration.įogmaster foggers can treat a large area very quickly 4-5,000 cubic feet per minute is fairly typical for a ULV (ultra low volume) application at a conventional dosage rate (1-2 oz/MCF). Instead, make an approximate calibration, using water (as a substitute for a water-based product) or light kerosene (for an oil-based one). Remember, first adjust the fogger for the desired particle size, then measure the liquid flow rate which produces that size output in your setting.ĭo not calibrate a fogger with a dangerous chemical (or an expensive one). Measure the time needed to discharge a known volume, then divide that volume by discharge time to compute the flow rate in ounces per minute (or cc/min).
