Linear Range		Smart electronics corrects for lower flow down to a Reynolds number of 5,000. The Reynolds
					number is calculated using the fluid’s actual temperature and pres-
					sure monitored by the meter. Rangeability depends on the fluid,
					process connections and pipe size. Consult factory for your applica-
					tion. Velocity rangeability under ideal conditions is as follows:
		Liquids 30:1			1 foot per second velocity minimum
						30 feet per second velocity maximum
		Gases 30:1			10 feet per second velocity minimum
						300 feet per second velocity maximum
